Signaling

For signaling and the functional monitoring of the power

supply two LEDs and an active signal output are available.

Using the rotary selector select the required functional

monitoring. The monitoring of the output voltage (DC OK) or

the exceedance of the output power threshold are available

(P

12.1

Rotary selector switch in position DC OK:

In this switch position the output voltage (U

If the DC OK threshold is exceeded (U

green DC OK LED turns on. Additionally, the signal output

(SIG) "active high" is active. If the output voltage drops

below the DC OK threshold value (U

DC OK LED flashes. The signal output is switched to "active

low".

12.2

Rotary selector switch in position >50 %, >75 %

or boost >100 %:

In each of these switch positions the output power (P

monitored. When the set threshold is exceeded the yellow

LED lights up (P

switches to "active low".
