Programming the Output

When the power supply is first turned on, it may take about 30 seconds or so to initialize the unit

before it is ready for use.

Set the Output Voltage

Set the Output Current

Enable the Output

Set the Output Voltage

You can set the output voltage when the output is either disabled (OFF) or enabled (ON). When enabled, the output

voltage will rise to the programmed setting. This assumes that a minimum output current has been programmed, that

the output has not reached its current limit or power limit boundary.

Front Panel SCPI Command

Turn the Voltage knob while observing the

voltage setting; or

Press the Voltage key, enter a value.

Then press Select.

To set the output voltage to 90 volts:

VOLT 90

When the unit is operating in constant voltage mode, CV status is displayed on the front panel.

Set the Output Current

You can set the output current when the output is either disabled (OFF) or enabled (ON). When enabled, the output cur-

rent will be limited at its programmed setting.

Front Panel SCPI Command

Turn the Current knob while observing

the current setting; or

Press the Current key, enter a Value.

Then press Select.

To set the output current to 100 amps:

CURR 100

When the unit is operating in constant current mode, CC status is displayed on the front panel.

Enable the Output

HAZARDOUS VOLTAGES All models generate voltages in excess of 60 VDC, with some

models rated at up to 1,500 VDC! Ensure that all instrument connections, load wiring,

and load connections are either insulated or covered so that no accidental contact

with lethal output voltages can occur.

Front Panel SCPI Command

Press the On/Off key. To turn the output on or off:

OUTP ON|OFF
