5.5 Control inputs

The internal switches S8, S9 and S104 are used to adapt the converter to the

available control signal (controller output signal).

The voltage and current inputs are separated from one another. The current

inputs (+,-) are arranged as differential inputs, i.e. they can have a maximum

common mode voltage of 7V with respect to the common ground potential (⊥).

If the current and voltage inputs are used at the same time, their effect will be

cumulative.

control inputs

The converter can be controlled through the following signals

(continuous power control):

- voltage signal (terminals 3, 4)

- current signal (terminals 1, 2)

-5-kΩ potentiometer (terminals 3, 4, 5)

For this purpose, a 10 V source is provided on terminal 5.

(switch settings are as for a 0 ... 10 V signal)
