* 1,000 V DC is the maximum allowable voltage.
The rating is 400 V DC.

Safety cutoff (AC and DC)

For Safety Cutoff on the AC side
Relays are used for safety cutoff on the grid (power network). The relay must cutoff the circuit to prevent abnormal currents that occur from affecting the commercial power supply. Power relays are required as safety measures to protect the power supply system.
* When using HE-S relay.

*Use one 2a1b type
(creation of contact welding monitoring circuit is possible).

For Safety Cutoff on the DC Side
Power relays are required as safety measures in the event of a defect in or malfunction of the battery or system.

Insulation detection

For Insulation Detection
PhotoMOS are used for monitoring quick charger stations for insulation deterioration.
If the insulation in a station deteriorates, a ground-fault current passes when the relay is turned on, and a sensor detects the current. High load voltage type PhotoMOS are ideal for use with quick charger stations, which carry high voltage.

Section with deteriorated insulation

Inside of a storage battery unit

If insulation is deteriorated in a section, a current passes when the relay is turned on.

(When insulation of high voltage area and chassis is deteriorated)
1. PhotoMOS is turned on.
2. The current sensor detects a ground-fault current.
3. An alarm signal is output.
