2.1 INTRODUCTION
The VSP SERIES power supplies are designed to deliver power in constant
voltage and constant current mode by switch mode conversion in sleek 1U high
cabinet and in a 19’’ rack construction.
This series comprises the two device soft switching technology that yields
very high efficiency of conversion for dc-to-dc converter part. Also it comprises
power factor correction circuity, which shapes the input current to follow the voltage
to maintain almost unity power factor at full load, and limits the current harmonics in
the input line.
It provides the user the option of isolated analog voltage, current and resis-
tance programming with built-in isolation amplifiers. It gives the option to monitor the
isolated signals with the option to change either from 0 to 5 Volts or from 0 to 10
Volts, for output voltage and current from 0 to full-scale level. It provides the display of
the output voltage, over voltage set level and current with 3-digit LED displays.
Piggyback series pass device ensures the ripple and noise levels to very low values.
Current sharing facility in the module gives the advantage to increase the power with
ease and the vents in the front and the rear enables it with absolutely zero stacking.
The module can be switched on/off through the front panel ON/OFF switch or re-
mote switch on rear panel.
VSP series provides digital interface options for remote programming from
PC. The digital interface provides 12-bit resolution for control as well as monitoring
the output.
