Remote control of output voltage
The output voltage of the power supply can be remote-controlled with an external voltage; the connection required is
shown in Fig. 4-4.

A.
Set the power supply INT-SLAVE switch to “SER-SLAVE” position.
B.
The “+” line of control voltage source is connected to the “SER” input terminal and the “-” line of control
voltage source is connected to the power supply output “+” terminal.
C.
The output voltage Eo is calculated as follows:
Eo: Output voltage of the power supply.
Er: Rated voltage of the power supply.
Ec: Remote control voltage.

For the remote voltage source Ec, use a device which provides a stable, low-noise voltage source
(an RS IPS series power supply or an equivalent device).
