About This Product

■For measures against abnormal voltages such as potential rise due to lightning surges

This is a power supply safety device that protects equipment from abnormal voltages such as potential increases caused by lightning surges, using the excellent protection effect of a high-voltage shield transformer. The electrostatic shield suppresses lightning surge voltage, so it can be used even if it does not coordinate with the voltage protection device inside the device. Types can be selected depending on the scale of lightning surge, purpose, and surrounding environment.

■Features

・Equipped with class I and II compatible SPD, can be used as a discharge type ・Performance evaluation is possible by conducting various tests using lightning impulse voltage and current testing equipment. ・Voltage-guaranteed discharge type (with SPD that operates close to the transformer's withstand voltage) reduces discharge frequency

■Ultra high withstand voltage 60kV (special performance type)

Demonstrates performance in environments where you do not want water to be discharged near power transmission towers or nearby areas.

■High performance dustproof and waterproof (special performance type)

Can be used under conditions that require high performance such as IP55

■Outdoor louver (special performance type)

Filter can be replaced from the outside

■Main locations of use

Communications, Broadcasting, Electricity, Computers, Disaster Prevention, Railways, Finance

■Others

For outdoor use, it is equipped with ventilation louvers (with filter).
