1. Technical description.
1.1 General description.
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilised voltage of
12 V DC (+/-15 %).
The PSU provides voltage of
U=13,8 V DC.
Current efficiency:
1. Output current 6 A + 1 A battery charge
*
2. Output current 5 A + 2 A battery charge
*
Total device c battery: 7 A max
*
.
In case of power decay, 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 9005) which can
accommodate a 17 Ah/12 V battery. A micro switch indicates door opening (front cover). TH35 rail, length of 185 mm, for
mounting the controller was installed inside. The PSU has been equipped with a LB4 fuse module to protect the controller
outputs.
