Product Details

GDZ09 DC high current solid state relay

Electromagnetic optocoupler isolation between input and output circuits.

Control signal compatible with PLC, TTL, PWM logic interfaces.

LED indicator for working status.

Built-in input under-voltage protection and output transient over-voltage absorption protection.

Solid-state, contactless output with fast switching speed, no sparks or arcing.

Encapsulated in epoxy resin, providing corrosion and shock resistance, ensuring stable and reliable switch operation.

The product is mainly used for controlling high-power DC power supply equipment such as PTC DC heaters, new energy conversion, battery charging and discharging, capacitors, etc.
