no.
Description
START button (launching from battery)
V
ADJ
potentiometer, adjustable output voltage
F
BAT
fuse in the battery circuit
Terminals:
~AC~ – AC power input
EPS – technical output of AC power loss indication
hi-Z state = AC power failure
0V state = AC power - O.K.
APS – technical output of battery failure
hi-Z state = failure
0V state = PSU status O.K.
+BAT- – terminals for battery connection
+AUX- – DC power supply output, (+AUX= +U, -AUX=GND)
Description: hi-Z – high impedance, 0V – connection to the ground GND
LEDs – AC – indication of presence of main power
LEDs – AUX – power supply output voltage indication
LEDs – LB – battery charging indication
Connector to the external LED indicators
