Introduction of composite power supply anti-lightning products:
Oumuleidun(OMRDON) composite series AC power supply anti-mine device(SPD/surge protector) for the protection of lightning protection of AC/DC power distribution equipment, such as program-controlled switches, security monitoring systems, background broadcasting systems, communications, fire control, industrial control systems, etc.. Prevent damage to the system or equipment caused by induced overvoltage and overcurrent caused by lightning strikes or surges. The product is beautiful in appearance, easy to install and connect, simple to maintain, and can work steadily for a long time in a relatively harsh environment.
The working principle of composite power supply anti-lightning device:
The surge protector(SPD) is an indispensable device in the lightning protection of electronic equipment. Its principle of action is that under normal circumstances, the surge protector is in a very high resistance state, thus ensuring the normal operation of the power supply system; When an overvoltage or overcurrent appears on the system line, the resistance of the SPD mutates or continues to drop to a low impedance, and the SPD immediately switches on within nanosecond time, releasing the surge energy through the SPD into the earth; After the surge, the surge protector quickly returns to high resistance,
Function characteristics of composite power supply anti-lightning device:
1, the maximum flow capacity: 20 KA(8/20 μS), using a two-stage composite balance of the safest circuit, differential mode(line to line), common mode(line to ground) full-mode protection, residual pressure, especially suitable for outdoor equipment, The lightning strike energy is large, and the residual pressure value requires a relatively harsh installation site.
2, no leakage, more stable performance, longer service life;
3, it has two levels of discharge, filtering, and clamping, so that the overvoltage and overcurrent can be effectively suppressed;
4, integration, small size, simple wiring, easy to install;
5, with LED lightning failure indicator light, normal(green) / failure(not light).

Application and installation position of composite power supply anti-mine device:
This series of surge protectors are suitable for Class D lightning protection and are used for lightning strikes at the junction of LPZO 1 or LPZO 2 and LPZ 03. It is usually installed on AC or DC power terminal equipment such as program-controlled switch, security monitoring system, background broadcast system, communication, fire control, industrial control system.
Attention to the installation of composite power supply anti-lightning device:
1 All ports at the anti-mine device output(OUT) are connected to the protected device.
The closer the anti-mine device is to the front end of the protected device, the better.
3, equipment needs to be regularly inspected, the product must be replaced immediately after deterioration.
Remember not to work live.
Grounding must be good and the grounding resistance is not greater than 4oumu.
