High Current Switch Mode Power Supply with Remote Sensing and Control
1. INTRODUCTION
This 900W switching mode DC regulated dual output power supply series provides high current with
constant current limiting protection, and variable output of 1.0 ~ 15VDC. It is designed with a highly efficient
Active Power Factor Corrector. The remote sensing terminal is used to compensate for long output line losses.
The output voltage level can be externally controlled via the remote control terminal.
2. PRECAUTIONS
● Never Short the Remote Sensing Terminal
● This power supply is for Indoor Use Only.
● Do not expose the power supply to sun, humid or dusty environment.
● Never remove the metal cover of the power supply while AC power is connected.
● Never touch the unit when your hands are wet.
● Never block the ventilation slots and cooling fan air intake window
● Never attempt to repair the power supply. Incorrect re-assembly may result in a risk of electric shock or
fire.
● Never use the power supply for the load requiring higher current than the designed value otherwise it
may damage the power supply.
● Place the power supply on a flat surface with sufficient clearance, dry, dust free surroundings for
ventilation.
