POWER SUPPLY UNIT - [ Type : PS 401H ]  
Technical Data

Power Supply PS401H has been exclusively designed for delivering higher power outputs upto a maximum of 200 Watts. This has additionally +/-6V DC at 7.5A in addition to the other low voltage outputs as given by PS401. It is designed to mate with the Standard Instrumentation Bin IB401. Both rack mounting and table top arrangements are possible. The LV supplies given out by this power supply are highly stable, with good regulation and low ripple.


  • Output rating 200 watts
  • Generates +/-6V D.C @7.5 amps, +/-12V D.C @3 amps and +/-24V D.C @1.5 amp
  • Noise & ripple : 10mV for +/-6V, +/-12V & +/-24V
  • Regulation better than +/-0.05% for +/-12V & +/-24V and +/-0.1% for +/-6V
