3.6. Running PSU on battery backup.
Power supply allows you to run on battery backup when necessary. To do this, press the START button on PCB.
4. Operation and use.
4.1. Overload or short circuit of the PSU output (SCP on).
The AUX output is equipped with an electronic protection. If power supply is loaded with current exceeding
IMAX. (load 110% ÷ 150% of PSU power), current and voltage are automatically limited. Voltage at output is restored
automatically after overload is removed.
In case of of the short-circuit to the AUX, BAT output, or incorrect connection of the battery, the fuse F
BAT
in the
battery circuit becomes permanently damaged and the restoration of the voltage at the BAT output requires the
replacement of the fuse.
4.2. Dynamic battery test.
The PSU runs a battery test every 5 minutes. It is done by a momentary output voltage reduction and voltage
measurement at the battery terminals. A failure is indicated when voltage drops below approx.12,2 (24,4) V
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 the case of
significant dust rate, its interior is recommended to be cleaned with compressed air. In the case of a fuse replacement,
use a replacement of the same parameters.
WEEE LABEL
Waste electrical and electronic equipment must not be disposed of with normal household waste.
According to the European Union WEEE Directive, waste electrical and electronic equipment
should be disposed of separately from normal household waste.
CAUTION!
The power supply unit is adapted for cooperation with the sealed lead-acid batteries (SLA). After the operation period they must
not be thrown but recycled according to the applicable law.
