12VDC 25Amp 18 Channel Battery Back-up CCTV power store / power station12VDC25A18P/B
Description:
12VDC25A18P/B: 12VDC 25Amp 18 Channel Battery Back-up CCTV Power Supply
The CCTV power supply is primarily designed for WUF-GV, PTZ and camera of CCTV system. It’s also used for access, building/house control, intrude alarm and other light-current. It is for desktop or wall-mounted installation.
Features:
ￚ Soft starting current, effectively reduce the impact of AC input, independent short-circuit protection and surge protection, resume automatically after clearing of fault, EMI filter, minimum ripple, 100% load test, quality guarantee, high efficiency, low T-rise, continuous duty
ￚ Input with a switch, LED indicators lighten when the power supply operates normally, and each output contains independent PTC, LED indicator, which is not interfere with each other
ￚ 12 Volt DC 25Amp switch mode power supply
ￚ 18 individually PTC auto-reset fuses protected outputs with LED
ￚ Backup battery: 12V 7AH
ￚ Charging Current: 350mA

Protection |
Over voltage protection |
When over voltage occurs, it will be switch to self-protection status to protect the load. |
|
Over current protection |
When over current occurs, the corresponding channel output will automatically switch to self-protection status, and the other channels output work normally, when clearing of fault, then switch back to normal. |
|
|
Short-circuit Protection |
When short-circuit occurs, the individual PTC fuse will break the circuit. When the fault is cleared, it will switch back to normal automatically. |
|
|
Charge |
The power supply will automatically switch to storage battery if there is outage. |
