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 model PWS1510MS-26.0-SRC Power Supply supplies
either 26, or 28 VDC from a 110 or 220 VAC power source.
Features
In a DC UPS ( Un-interruptible Power Supply ) , the charger simultaneously powers the DC load
as well as the battery. As long as the AC power to the charger is available and the charger is
working normally, the charger will supply the DC load as well as charge / float the battery. In
case the AC power fails or if the charger stops working, the battery will automatically power
the DC load. As soon as the AC power to the charger is restored, the DC load will once again
be fed by the charger and at the same time the battery will be recharged. CAUTION! Please
ensure that the sum of the current drawn by the DC load and the current desired for charging
the battery is less than the maximum current capacity of the charger. To use as a DC UPS, first
switch off the DC load and connect it to the battery. Now connect the battery. Switch on the
charger and then switch on the DC load.
