12VDC 25Amp 18 Channel Battery Backup CCTV Power Supply (12VDC25A18P/B)
12VDC 25Amp 18 Channel Battery Backup CCTV Power Supply (12VDC25A18P/B)Descrition:12VDC25A18P/B: 12VDC 25Amp 18 Channel Battery Back-up CCTV Power SupplyThe CCTV power supply is primarily designed for WUF-GV,Website:, 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:1. 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 duty2. 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 other3. 12 Volt DC 25Amp switch mode power supply 4. 18 individually PTC auto-reset fuses protected outputs with LED5. Backup battery: 12V 7AH6. Charging Current: 350mA7. Switch mode power supply (regulated voltage)8. Integral surge protection9. Individual LED power indication10. Individual PTC reset-able fuses 11. Internal On/off safety power switch with LED indicator12.
