Output Specification

Stability 0.05%

Efficiency

< 80% Minimum

Transient Response 250 microseconds for load change from 40% to 90%

Mode Of Operation

Local Mode Through front panel potentiometer for voltage, current and

over voltage and Push switch for Output ON/ OFF control.

Remote Mode Interface Analog programming of voltage

and current.Voltage: 0 - 5 volts or 0 – 10 volts for output

voltage and current, selection through DIP-switch.

Resistance: 0 – 4.85k ohms from 0 to full-scale level.

Digital Interface RS-232 / GPIB

* = Specification also apply to corresponding GPIB model

F.S = Full Scale. Full scale will be different for each model. Example: If you have a VSP2050

and you are measuring the voltage meter accuracy, the meter can not off more than 0.3V

(20V + 0.2% +3 digit). Note: 3 digits refferes to the power supply displays least significant digit.
