1. INTRODUCTION

1.1 The APC (APL) Non-Standby Power Supply

Product Description:

Alpha APC (APL) Series non-standby power supplies provide conditioned power to

signal amplifiers in Cable Television and Broadband distribution systems. The

modular design, which consists of a baseplate, transformer assembly and enclosure

cover, supplies the load with current-limited, regulated AC power that is free from

disturbances caused by spikes, surges and other forms of power line transients.

AC power enters the module where it is converted to a “quasi” square wave and

regulated (at the required output voltage). It is then passed on to the load via the

VSF fitting located on the baseplate assembly. The modular design of the APC and

APL Series of non-standby power supplies allow for easy upgrades (or downgrades)

depending on the particular power application simply by replacing the transformer

assembly, thus saving time and money.

The versatile APC (APL) Series non-standby power supply is designed to be pole-

mounted (wooden or concrete), wall mounted, rack mounted, shelf mounted, or

pedestal mounted. Operator controls are located inside the enclosure on the main

transformer assembly. The APC (APL) includes an AC input circuit breaker, output

fuse, *output receptacle, VSF fitting, and external grounding clamp. The APC (APL)

can also be equipped with various options including: a *Time Delay Relay (TDR-M)

to suspend power to the output from 10-60 seconds during utility start-up after an

AC outage has occurred; a Plug-in Lightning Arrestor (LA-M) to provide additional

protection from voltages spikes caused by lightning or other power line disturbances;

a Status Indicator LED (SIL-C) to indicate acceptable output power is being supplied

to the load; a plug-in *Amp-Clamp (ACAT-3P) to provide “Crowbar” clamping

protection from voltage spikes in excess of 104 volts; an *Ammeter (AMM-C) to

display output current to the load; and an Enclosure Security Lock (GLK) for

additional security in accessible areas.

The APL is a low cost, compact version of the APC non-standby power supply and

features all of the transient and spike protection found in the APC. Options include;

SIL-C; LA-L; and GLK, described above.

The APC (APL) series, along with the entire line of Alpha power products, are

designed to be one of the most rugged, reliable, and versatile power supplies

available. Alpha Technologies, recognized as an international market leader in the

field of backup power, offers complete technical support and prompt, reliable service

to ensure that your power supplies continue to provide you with years of trouble-free

operation.

* These options are not available for APL Series non-standby power supplies.
