Constant Current Operation

To set up the power supply for constant current operation:

a.With power supply turned off, connect the load to the output terminals.

b.Turn on the power supply. Hold in DISPLAY OVP pushbutton switch and set OVP ADJUST potentiometer for the desired OVP trip voltage. In CC mode the voltage setting will limit output voltage under quiescent conditions, and the OVP circuit provides added protection against hardware faults.

c.Hold the DISPLAY SETTINGS pushbutton switch in, and rotate the VOLTAGE control to set desired voltage limit.

d.Adjust the output current to the desired level. The CC indicator should be on.

e.If a load change causes the voltage limit to be exceeded, the power supply automatically crosses over to constant voltage operation and the output current drops proportionately. In setting the voltage limit, make adequate allowance for voltage peaks that could cause unwanted mode crossover.

Remote Voltage Sensing

The remote sensing connections shown in Figure 3-6 improve the voltage regulation at the load by monitoring the voltage there instead of at the supply’s output terminals. Remote sensing allows the power supply to automatically increase the output voltage and compensate for the voltage drops in the load leads. This improves the voltage regulation at the load, and is especially useful for CV operation with loads that vary and have significant load-lead resistance. Note that with remote sensing, the internal voltmeter is connected at the load. Remote sensing has no effect during CC operation. When using remote sensing, turn off the power supply before changing the rear-panel straps, sense leads, or load leads. Connect the unit for remote voltage sensing by connecting load leads from + OUT and - OUT terminals to the load, disconnecting straps between + Out and + S and between - Out and - S, and connecting sense leads from the + S and - S terminals to the load as shown in Figure 3-6.

Note: Sensing is independent of other power supply functions; either local or remote sensing can be used regardless of how the power supply is programmed.

The load leads should be of the heaviest practical wire gauge, at least heavy enough to limit the voltage drop in each load lead to 0.5 volts. The power supply has been designed to minimize the effects of long load-lead inductance, but best results will be obtained by using the shortest load leads practical.

Note: The OV circuit senses the voltage at + Out and at the output side of the internal current sampling resistor in the – output lead. Remote voltage sensing compensates for a voltage drop of up to 0.5 V in each load lead, and there may be up to 0.12 V drop between the – output and the internal sensing resistor at the point the OVP circuit is connected. Therefore, the voltage sensed by the OVP circuit could be as much as

1.12V more than the voltage being regulated at the load. It may be necessary to readjust the OVP trip voltage to compensate for these drops when remote sensing.
