Potentiometer for the output voltage

Designation (C)

Description

Potentiometer cover

Open the flap to adjust the output voltage. Factory setting: 24.1 V

DC-OK LED

Designation (D)

Description

LED green

Lights when the output voltage has reached 90% of the set output voltage.

DC-OK relay contact

Designation (E)

Description

Push-in terminals
13 / 14

Monitors the output voltage of the active power supply.
See chapter on DC OK relay contact for more information.

"Parallel Use" "Single Use" connection

Designation (F)

Description

Push-in terminals
"Link for parallel use"

Connect the two terminals when power supplies are connected in parallel. In order to achieve a distribution of the load current to the individual power supplies, the output voltage is regulated in parallel connection mode such that the voltage at no load is approx. 4% higher than at nominal load. See also chapter on Parallel use for power increase.
