3 Operating the Power Supply Locally

Set the programming sources to the desired levels and turn the power supply on. Adjust the programming sources to change the power supply output.

The analog control circuits let you set the output voltage and current limit up to 5% over the model-rated maximum value. The power supply will operate within the extended range, however it is not recommended to operate the power supply over its voltage and current rating, and performance in this region is not guaranteed.

Resistance Programming of Output Voltage and Current

Resistances of 0 - 5 kor 0 - 10 kcan be selected to program the output voltage and current limit from zero to full scale. Internal current sources supply a 1mA current through the external resistors. The voltage drop across the resistors is used as the programming voltage for the power supply. To maintain the temperature stability specification of the power supply, only use resistors that are stable and low noise, with a temperature coefficient less than 50ppm.

Set the power supply to resistance programming as follows:

Make sure that the power supply is turned off.

Set SW1 setup switch 1 (for voltage) and 2 (for current) to the UP position.

Set SW1 setup switch 3 to select programming resistance range according to the following table.

Set SW1 setup switch 7 (for voltage) and 8 (for current) to the Up position to enable resistance programming.

Connect a short between J1 pin 8 and J1 pin 12 (see figure).

Connect the programming resistors to the mating plug of J1 as shown in the following figure. A variable resistor can control the output over its entire range, or a combination of variable resistor and series/parallel resistors can control the output over a restricted portion of its range.
