RED LED:
on – the PSU is supplied with 230V AC
off – no 230V AC supply
GREEN LED:
on – DC voltage in the AUX output switch mode PSU 27,6V DC
off – no DC voltage in the AUX output output switch mode
PSU 27,6V DC
3. Operating status indication.
3.1 LED indication of operating status.
The is equipped with two diodes on the front panel:
4. Operation and use.
4.1 Overload or short circuit of the PSU output (SCP on)
The converter output is protected with a PTC polymer fuse. If the load of the PSU exceeds Imax. (Load
110% ÷ 150% @ 25ºC of the PSU power), the output voltage is automatically disconnected. The voltage restoration
at the output requires disconnecting the output load for the period of approx. 1 minute.
In the case of short circuit of the PSU output, the F
AUX
F1,5A fuse becomes permanently damaged.
Restoration of voltage at the AUX output requires fuse replacement.
4.2 Disconnection of discharged battery.
The PSU is equipped with the discharged battery disconnection system. During the battery-assisted
operation, reducing voltage below 9,5V at the battery terminals will cause battery disconnection.
4.3 Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU from the
power supply network. The PSU does not require performing any specific maintenance measures, however, in
case of significant dust rate, its interior is recommended to be cleaned with compressed air. In case of fuse
replacement, use a replacement of the same parameters.
