High-capacity Power Relays for Storage Systems G9KB Series

Technology / Service Summary

A high-capacity hydrogen gas-free relay that supports a contact voltage of DC800V and a contact current of 100A. By using a PCB type terminal without using screws, the man-hours required for mounting on a printed circuit board have been reduced.

Purpose

A DC bidirectional relay developed for 15 to 45 kW devices and systems, such as energy storage systems and EV chargers that help realize a carbon-free society.

Feature

A gas-less type that does not contain hydrogen gas inside the product, this high-capacity DC relay is suitable for applications such as storage batteries and power distributors that require safety and reliability. The advantage of the gasless type is that it can open and close in both directions simultaneously, allowing charging and discharging at the same time, so there is no need to use multiple relays in equipment or systems, reducing the number of relays used and the number of parts. In addition, by using PCB terminals instead of terminal screws, it is possible to reduce the labor required for printed circuit board assembly, improving not only design freedom but also manufacturing productivity.

Effect

This technology will facilitate the visualization of GHG emissions throughout the entire supply chain in the electrical equipment industry, and contribute to the realization of a decarbonized society globally.
