Overview:
Input 110/220 V AC
Output 12V DC.8channels
20 Amp Supply Current
Integral Surge Protection
Individual LED Power Indication
Individual PTC Output Protection
Max. Amp: 2.5Amp/ch
1.2U rack mount
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 duty
2.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
3.Convenient installation, save a lot of time and labor
4.Packing with color box

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, individual PTC fuse will break the circuit, when clearing of fault, it switch back to normal automatically. |
