Voltage and Current Programming of the E3614A/15A/16A/
17A with a Voltage and Current Source
Remote analog voltage programming permits control of the regulated output voltage
or current by means of a remotely varied voltage or current. The stability of the
programming voltages directly affects the stability of the output. The voltage control
or current control on the front panel are disabled during analog programming.
NOTE The CV(-) terminal on the rear panel is internally connected to the plus output
terminal. In following connections, it is recommended to use Figure 2, Figure 4, or
Figure 6 if the negative terminal of the “Programming Voltage” is not floted from
its circuits.
Constant Voltage Mode
The programming voltage is not isolated from the power supply output. The power
supply may be programmed with a voltage that is common to either the plus output,
or the minus output.
