PSDCB09129C Buffer power supply 13,8 V DC for up to 9 HD cameras
The indicated price is valid ordering till 19.04.2026.
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 9x1 A + 1 A battery charge
2. Output current 9x0,66 A + 4A battery charge Total device current + battery: 10 A max.
In case of power decay, a battery back-up is activated immediately. The approximate backup time is given assuming that all output ports are used (using typical devices and 17Ah batteria). The electricity consumption for own needs and the energy efficiency of the power intake track were taken into account. The exact description of how to perform the calculations can be found at: .
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 17Ah/12V battery. A micro switch indicates door opening (front cover).
