High Power 12V (13.6V) power supplies with very low noise for use with high end audio equipment.

1340 watt power supply for marine and commercial audio use These high-efficiency voltage-regulated power supplies have the unique ability to actively limit their current when put in an overload condition. They will reduce (fold back) the voltage in order to keep the current within safe limits without shutting off or hiccoughing. Among other things, this feature allows a lead acid battery to be operated in parallel with the load--the battery will be charged and maintained, and is available to supply extra current to the load under unusual spikes (such as audio bursts) or supply the load when the AC power fails. Useful for automobile showroom and indoor expositions. It prevents the car's battery from dying from opening the doors or demonstrating the car's electronics. When used in parallel with the car's battery it can also keep it topped-off without overcharging.

PST-APS-100


Suggested Applications: Audio Display, Demo & Show Vehicles Marine & Recreational Vehicles; Battery maintenance & storage Retail Store Displays, Industrial Applications (available in 24V output) Communications

High efficiency, switchmode power converters. These AC-DC power supplies have a nominal output voltage of 13.4 volts. They were originally designed to power automobile audio systems in demonstration rooms and trade shows. They have very low ripple and no audio noise. Other output voltages can be made upon request, or you can adjust the voltage in the field with a screwdriver.
These AC/DC Power Converters are ideally suited for the mobile environment. These power supplies feature regulated and filtered outputs which allow for clean audio demonstrations without the slightest hint of noise.
Their low profile design allows for convenient mounting under a display vehicle or behind a display board. APS series power supplies may be used with or without a battery. When combined with a high quality battery, APS units can supply transient surges up to 1000 amps. Can also be used in installations where use of a battery is not possible.
All models except the PST-APS-100 offer dual voltage output. (13.4VDC - 14.4VDC)
Virtually Silent Operation All APS Power Supplies utilize an advanced switching design. There is no low frequency transformer hum. Every unit is equipped with a cooling fan that is virtually silent, and only comes on as needed.
The PST-APS Power Supplies all feature thermal control circuitry that engages the fan only when internal temperatures require it (typically 75% of full load). They have small compact sizes compared to the transformer based power supplies. The switch mode technology utilized in APS Power Supplies boasts 86% efficiency. This superior design results in cooler operating temperatures and compact size.
Up to six of these lightweight power supplies (identical models only) can be connected in parallel for even greater current capability.
Adjustable from approximately 11.5 to 15 volts with internal potentiometer (adjustable through a hole from outside the box)

* The PST-APS90, PWS1503-110-12 and PST-ABP100 are designed to exceed UL requirements.

**The dual-voltage feature allows the voltage to change from 13.6 to 14.4 volts by inserting jumper into a socket.

Typical AC outlets are 1540VA, 14 amp service. To run the higher power units you will need higher power service. Please consult competent technical authorities to determine the total load on the circuit you intend to supply the power with, including other things plugged into the same line.
