1. Technical description.
1.1 General description.
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilised voltage of
12V DC
(+/-15%).
The PSU provides voltage of
U=13,8V DC.
Current efficiency:
1. Output current 18A + 2A battery charge
*
2. Output current 16A + 4A battery charge
*
3. Output current 12A + 8A battery charge
*
Total device c battery: 20A max
*
.
In case of power decay 230V, a battery back-up is activated immediately. The PSU is constructed based
on the switch mode PSU, with high energy efficiency. The PSU is housed in a metal enclosure (colour RAL 9003)
which can accommodate a 65Ah/12V battery.
The power supply is equipped with relay and the OC type technical outputs indicating power failure, the
failure of the power supply and low battery voltage.
A micro switch indicates door opening (front cover).
The power supply housing has space for additional modules (fuse blocks, voltage regulators and DC-DC
converters). Optional power supply configurations are available at the website:
