INTRODUCTION
All new Current Mode switching design offers increased power and reliability in a compact package.
Extra input and output filtering reduce EMI to extremely low levels. Reliability features include an
input fuse, thermal shutdown, current limiting and output short circuit shutdown with automatic
recovery. The output voltage is easily adjusted 0.5 volts above or below the standard output voltage.
The model PWS1000 Power Supply supplies either 12, 24 or 48 VDC from a 110 or 220 VAC power
source. 1 or 2 high quality analog meters can be added (factory option) to allow monitoring of
charging current and charging voltage. Other output voltages up to 72 volts are also available by
special order.
