Cctv&dvr Network Switch Power Supply /300W Switching Power
Supply
Actual Power: 300W
Input Voltage:AC110V~240V 47~63Hz
Output Voltage:DC12V 25A
N.W:1120G
Size (mm) 261*104*65mm
Stable circuit design, wide input voltage,precisely stable voltage,
to have the multiple protecions for over-voltage, overload, short
circuit and overheat; Output ripple is small; to pass the 100% long
time aging test, and own high efficiency, long lifespan and high
reliability; the outward appearance is exquisite, easy to use.
