High Power 12V (13.8V) Battery Chargers for Electric Vehicle Auxiliary Systems

1340 watt power supply for marine and commercial audio use line drawing of the high power low noise audio power supplies 800 watt power supply for electric vehicle auxiliary systems
800 Watt DC converters for electric cars that need no fan for cooling
PST-APS-30  

Suggested Applications: Charging 12 volt batteries from 120V, 128V, and 144V, 240V, 288V, 360V electric car batteries.

High efficiency, switchmode power converters. These DC-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.
These DC/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.
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. 24V output versions are also available.

* Full power operation with 130-190VDC operation. The charger works at lower voltages 100-129, but at reduced charge current. Under 100 volts there is virtually no charging current available, but the charger will not be damaged.

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