Description

Product manual

Lefedi power surge protector refers to the national standard GB/T18802.21-2004/IEC61643-21:2000 to design DC power surge protector, specially used for DC power surge protection, it adopts series protection mode, built-in overcurrent The overvoltage suppression unit makes the protected DC power supply safer and work stably. DC power surge protectors are divided into four specifications: 12V, 24V, and 220V, corresponding to different voltages, to protect the power supply.


Product advantages

◆ Installed at the power port of the equipment, used for lightning protection and anti-surge protection of power lines

◆ 3 voltage levels 12V, 24V, 220V, to meet different power equipment;

◆ Series installation, lower residual voltage, load current 10A;

◆ Temperature control protection, immediately interrupt the power line after the product fails.
