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
F3,15A 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 19V 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.
