SPS-3

3/1.5A Switching Power Supply with Charger

12/24 VDC Selectable Output

The SPS-3 are heavy duty self contained, efficient clean with linear performance off-line switching power supplies that are selectable between 12 VDC at 3A, and 24 VDC at 1.5A. With the universal AC input, these supplies may be connected anywhere in the world with no plug-in transformer or any alterations. These power supplies have exceptional brown out capability with operation down to 60 VAC. The extensive filtering system provides a very clean DC output with linear performance. All of the supplies are power limited and thermally protected. All output faults are self restoring.

The SPS-3 has a precision lead acid battery(s) charger that obtains maximum battery life while providing a 12 or 24 VDC uninterruptible power supply. The SPS-3 are protected against Battery(s) reversal, shorting or overloading.

Before connecting load and battery(s), set 12/24V selector jumpers to the desired voltage. Caution, damage will occur if jumpers are moved with DC output load or Battery connected. Confirm proper voltage before connecting devices.

The SPS-3 has the additional supervisory features of a set of form “C” relay contacts that indicates AC power status, and a special electronic circuit that limits the output current to provide class II power limiting and load disconnect when battery(s) is depleted.
