1. Technical description.
1.1 General description.
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilised voltage of
24V DC (+/-15%).
The PSU provides voltage of
U=27,6V DC.
Current efficiency:
1. Output current 9A + 1A battery charge
*
2. Output current 8A + 2A battery charge
*
3. Output current 6A + 4A battery charge
*
Total device c battery: 10A 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 2x17Ah/12V battery. 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:
