CAUTION!
In the Fig.2. the set of contacts shows a potential-free status of the relay which
corresponds to a state with no DC power (PSU failure).
FLB
– technical output indicating battery voltage
:
- OC type output. Under normal status (U
BAT
> 11,5V) the output is connected to ground (L level
– 0V). In case
of decrease of battery voltage (U
BAT
< 11,5V) the output is switched into high impedance state
– hi-Z.
- relay output. In case of a battery voltage drop U
BAT
< 11,5V, the contacts of the relay change over.
CAUTION!
In the Fig.2. the set of contacts shows a potential-free status of the relay which
corresponds to a state with low battery level (U
BAT
<11,5V).

4. Operation and use.
4.1 Overload or short circuit of the PSU output (SCP on).
In case of overload, the output voltage is automatically shut off, and so is the LED indicator. The restoration
of the voltage takes place immediately after the failure (overload) is over.
4.2 Battery-assisted operation.
In case of a main power outage, the device is immediately switched into a battery-assisted operation.
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.
