Product Description

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:

 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

 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

 12 Volt DC 25Amp switch mode power supply 

 18 individually PTC auto-reset fuses protected outputs with LED

 Backup battery: 12V 7AH

 Charging Current: 350mA

 Switch mode power supply (regulated voltage)

 Integral surge protection

 Individual LED power indication

 Individual PTC reset-able fuses

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.
