V
ADJ
potentiometer, voltage adjustment DC
[5]
Connectors:
+BAT-
DC supply output of the battery
(+BAT= red, -BAT=black)
+AUX-
DC supply output
(+AUX= +U, -AUX=GND)
FAC -
AC absence technical output – OC type (open collector)
level hi-Z = state: AC power supply failure
level L = state: AC power supply
FPS
- technical output of power supply operation status – OC type (open collector)
level hi-Z = state: failure
level L = state: correct operation

Optical signaling of operation LED:
AC
- LED diode that indicates the presence of AC voltage
LB
- LED diode that indicates battery charging
AUX
– LED signaling presence of output voltage
