Manson Engineering Industrial SPS-9620 User Manual

High Current Switching Mode Power Supply with Remote Sensing User Manual

1. INTRODUCTION

This switching mode DC regulated power supply provides high current with constant current limiting
protection. It has a fixed 13.8V output with rated current up to 120A. It is designed with a high efficient
Active Power Factor Corrector. The remote sensing terminal is used to compensate for long output line
losses.

2. PRECAUTIONS

● Never Short the Remote Sensing Terminal
● Do not expose the power supply to sun, high humid and 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.
● The power cord provided is only for 230Vac input. If the input source voltage is below 190Vac, the
power cord should be replaced by a 1.0mm

3. INSTALLATION

● This power supply is for Indoor Use Only.
● Place the power supply on a flat surface with sufficient clearance, dry, dust free surroundings for
ventilation.
