Unit Power Capacity

The H15 Power Conditioner is rated for 1440 Watts (continuous). It has been designed, however, to support component inrush currents that are much higher than its continuous power rating. The H15 is capable of supplying the dynamic peak current draws required by any component designed to work on a 15 amp circuit. Despite their nameplate power ratings, high performance AV equipment draw much less than their listed power ratings. The H15 can inform the user how much of the power capacity is available as equipment is connected to the unit

Features

Automatic Voltage Regulation (AVR)

The H15 is unique in that it provides AVR, which is engaged to correct low and high voltage conditions. In doing so, all equipment connected to the H15 are protected against these undesired voltage fluctuations, thus, prolonging the life of the equipment.

Surge Protection

The H15 Power Conditioner provides a high level of surge protection for the voltage going into the unit, thus protecting the devices connected to the unit. Additionally, surge protected coax/radio frequency (RF) connectors are protected against surges traveling over coaxial lines to protect your digital satellite system (DSS), CATV box, or cable modem. Similarly, the telephone line surge protection feature provides a protected splitter to allow output to a phone, modem, fax, digital video recorder (DVR), WebTV system, or pay-per-view cable TV function.

Isolated Noise Filter Banks (INFB)

The H15 also provides INFB technology to eliminate electromagnetic and radio frequency interference that can negatively impact sound and video quality.

DC Trigger

This feature works only with receivers that have DC triggering capabilities. For more information on how this works, or to find out if your system has this capability, please refer to the user’s manual for your receiver.

CAUTION: When connecting to the DC Trigger jacks, connect the source of the DC trigger to the IN jack. The OUT jack should be used only as a pass-through. The DC Trigger signal can be short circuited if the input and output cables are reversed. The maximum input voltage for the DC Trigger is 30VDC. Do not apply an AC voltage to the DC trigger jacks. Failure to comply with this statement may result in equipment damage.

Sequenced Turn ON/OFF

Ensures that connected equipment is powered up or down in the proper order and with the right amount of delay between the stages. This feature helps you to eliminate any “popping” sounds coming from your speakers when you turn on your system. It allows you to program a delay into the sequence between 0 and 12 seconds. Please refer to the user’s manual of your amplifier or receiver for more information on how much delay is required.

LCD Display and Unit Customization

The LCD displays important information including voltage in (line voltage) and voltage out, frequency, and load. Additionally, the LCD is used to program features such as the delay or dimmer settings. For convenience, all information provided in the display can be set to English, French, or Spanish.

Overload

The overload feature is designed to proactively notify the user if the unit and corresponding circuit are overloaded.

Removable Support Feet

Feet can be unscrewed and removed to save space when rack mounting.

The rear panel connectors for the H15 Power Conditioner are detailed in Figure 3. Each numbered callout refers to the numbered description found in the following pages.

Figure 3. H15 Rear Panel ConnectorsNote: All outlets provide surge protection, voltage regulation, and noise filtering.

  1. AC-Powered OutletsThe H15 Power Conditioner provides for connection of up to twelve (12) AC-powered devices. The outlets are arranged according to the type of filtering protection provided for a given application. These Isolated Noise Filter Banks eliminate electromagnetic and radio frequency interference that can negatively impact sound and video quality. APC recommends you plug your devices into the outlets as marked, in order to assure optimum protection for your equipment. The outlets are further defined in the following:Digital Filter Outlets provides filtering of the incoming AC power to protected your most sensitive digital devices (CD, DVD, DVR, CATV/SAT, Monitor, and AUX (one auxiliary digital device).Note: Any digital device can be plugged into the digital outlets, any video device can be plugged into either of the video outlets, etc. Example, if you have a cable box and a satellite receiver, but no monitor, you can plug the cable box into the “CATV/ SAT” outlet, and the satellite receiver into the “Monitor” outlet. Video Filter Outlets provide filtering for your video devices (TV and VCR).Analog Filter Outlets provide filtering for your analog-based equipment (Tuner/AUX and Preamp/Receiver).High Current Filter Outlets provide filtering for your high current devices (Subwoofer and Amplifier).
  2. Surge Protected COAX/RF ConnectorsThe H15 provides a cable splitter for your CATV system or Cable Modem. The surge protection feature prevents surges traveling over Coaxial data lines from damaging the system. Connect the coaxial cable from the CATV or Cable Modem provider to the connector marked “IN”, connect other cables from the connectors marked “OUT” to the device being protected (CATV box or Cable Modem).
  3. System Ground TerminalThe H15 provides for the connection of grounding wires from all of your equipment to a central terminal lug. This ground connection eliminates ground loop problems; tie all component grounds to this screw to break any possible ground loops that can cause an audible ‘hum’.
  4. Circuit BreakerThe H15 also provides a “press-to-reset” circuit breaker. When this breaker is “tripped” due to an electrical surge or overload, the device pops out and shuts down output power to the outlets. To reset the circuit breaker, push it straight inward.Caution: When resetting the Circuit Breaker, push the button in quickly, and release the button. Do not hold the button inward. Failure to comply may result in equipment damage.
  5. Input Power ConnectorConnect one end of the supplied AC power cord to the H15 Input Power Connector, connect the other end to the AC utility power source (12 Amp, 120 Vac, 50-60 Hz).
  6. DC Trigger jacksWhen connected to a component acting as a DC trigger, that component controls turn on/off of the ‘delayed’ outlet banks. The H15 also allows that DC signal to pass through to another connected component.CAUTION: When connecting to the DC Trigger jacks, connect the source of the DC trigger to the IN jack. The OUT jack should be used only as a pass-through. The DC Trigger signal can be short circuited if the input and output cables are reversed. The maximum input voltage for the DC Trigger is 30VDC. Do not apply an AC voltage to the DC trigger jacks. Failure to comply with this statement may result in equipment damage.
  7. Surge Protected Telephone JacksThe H15 provides a telephone line splitter with surge protection to protects components connected via telephone line. Connect the supplied RJ11 Telephone cable from the wall jack (source) to the telephone line connector marked “IN”. Connect other telephone cables to the connectors marked “OUT A” and/or “OUT B” and then to the equipment to be protected (Telephone, DVR, DSS, or DSL).
  8. Additional Surge Protected COAX/RF ConnectorsThe H15 also provides a surge protection for your DSS system or RF Antenna system. The surge protection feature prevents surges traveling over Coaxial cable from damaging the equipment. Connect the coaxial cable from the DSS or Antenna system to the connector marked “IN”, connect another coaxial cable from the connector marked “OUT” to the device being protected (DSS or Antenna).

Installation

The installation of the H15 consists of the following steps:

  1. Making Connections
  2. Applying Power
  3. Setting Up the H15

Making ConnectionsNote: Whenever the H15 is plugged into a utility AC power source, the microprocessor is active and the unit monitors the input power (standby mode).

Prior to connecting equipment to the H15 Power Conditioner, ensure the unit is functional by connecting the AC Power Cord (provided) at the rear panel ( 5, Figure 3). Once power is applied to the unit, the display provides the following messages:

  • If the unit was in the ON state before the AC input went off, the unit will automatically turn on the outlets again when the input power is restored. The display menu will also be restored.
  • If the unit was in the STANDBY state before the AC input went off, theunit will remain in the STANDBY state and there will be no LED or LCD display.

Note: Due to the unique filtering and surge protection provided by the H15, APC recommends connecting AV components as noted on the rear panel of the unit (Figure 3).

Connect your AV components as noted on the rear panel, and as defined in the section “REAR PANEL CONNECTORS”. To ensure ground loops are eliminated, thus eliminating an audible hum through your speaker system, ground all AV components to the Ground System terminal located on the rear panel of the unit ( 3 , Figure 3).

Applying Power

Apply power to the H15 by pressing the front panel Power Switch ( 9, Figure 1) fully inward, then releasing the switch. Once power is applied to the unit, the display shown in Figure 4 is illuminated.

Figure 4. Voltage In/Voltage Out Display.

Note: In the display shown in Figure 4, the input and output voltages are the same. (The actual voltage may vary depending on the power supplied by your utility.) In this case, both voltages are within acceptable ranges, thus, the H15 does not have to “clean up” the output voltage.

Setting Up the H15

Using the front panel Setup and Select push buttons ( 12 and 8 in Figure 1) you can configure various functions provided by the H15 (Dimmer, AVR Range, Delay Time, Beeper, or Language (English, French, or Spanish)), as defined in the following paragraphs:

Troubleshooting

This section describes possible causes and solutions for the following problems:

  1. Unit will not turn on.
  2. The overload LED is lit.
  3. “Wiring OK Indicator” LED is not illuminated.
  4. The Line Boost and Line Trim LEDs are flashing.

Unit will not turn on.Probable Cause: Input power cord is not connected properly.Solution: Ensure supplied power cord is connected firmly at both ends.Probable Cause: No power or insufficient power available at the wall outlet.Solution: Ensure the wall outlet has good power by using a voltmeter, or by plugging in another device.Note: The unit will not turn on and accept incoming utility power if the power is out of range.

Probable Cause: Circuit Breaker has tripped.Solution: Check both home and unit circuit breakers. If the circuit breaker located on the rear of the H10 has tripped, the center post will be extended outwards about a quarter to half inch. Push it back in to reset it. If the trip occurs again, reduce the amount of equipment plugged into the unit and try again. While the unit’s breaker is rated for 15 Amps, National Electric Code (NEC) dictates that any particular home circuit should not be loaded more than 80% of its rating.

The overload LED is lit.Probable Cause: Unit was overloaded.Solution: There is an “Overload” LED on the front display panel which will light ‘red’ if the unit is overloaded. If the unit is overloaded or nearly overloaded (>95%), it is recommended that the load be reduced by unplugging one or more components.

“Wiring OK Indicator” LED is not illuminated.Probable Cause: There are 3 reasons why this LED would not be illuminated:

  1. Reversed polarity exists at the wall outlet.
  2. Neutral wire is overloaded.
  3. Earth ground is missing at the wall outlet.

Solution: Operating the unit under such conditions may impact its surge protection performance. Contact an electrician to have them inspect the building or home wiring to fix the problem.

Probable Cause: Unit is on but LEDs are turned off.Solution: Push the Setup button, push the Select button two or three times. The LEDs should illuminate. Choose the dimmer setting (see the sections on “Front and Rear Panels” and “Setup the H10”).

The Line Boost and Line Trim LEDs are flashing.Probable Cause: One of the inner relays is welded.Solution: Remove the input cord and then plug it in again. If the problem remains, contact APC.
