40KA 110V DC Power Lightning Arrester

A Power Surge Protector (SPD), also known as a lightning arrester or surge protector, is essential in the information age. As computer networks and communication equipment become increasingly sophisticated, they require stable working environments. Lightning and transient overvoltage from large electrical equipment can invade indoor electrical and network systems through power supplies and antennas. This can cause severe damage to components, data loss, system crashes, and significant economic impact. The power lightning arrester utilizes modern electrical technology to effectively prevent lightning strike damage.

• The lightning arrester is connected in parallel with the DC power supply line.
• During installation, connect the "+" and "-" signs on the arrester terminals to the "positive" and "negative" lines of the DC power supply.
• The "PE" sign terminal must be connected to the grounding wire.
• The wiring method uses a secure screw fastening type.
• Status Indicator: The green window indicates normal working status, while the red color indicates a fault status, meaning the module needs to be replaced.
