Environmental calculations for high-capacity power relays for storage systems
Omron is to start providing carbon footprint data of products (PCF) calculations for high-capacity power relays for energy storage systems and other new equipment to customers from May 2024.
Omron will promote visualization of greenhouse gas (GHG) emissions throughout the supply chain in the electrical equipment industry for its latest relays.
For green procurement in the supply chain, the use of PCF disclosure as a policy for selecting suppliers has been increasing, and it is becoming necessary for companies to implement PCF calculations.
- Omron sealed power relays extend switching current
- Extended temperature rating boosts power relay PCB density
Omron has established its own calculation guidelines for PCF based on global standards for its G9KB series of high-capacity power relays for new energy devices such as power conditioners and storage systems.
The PCF for the relays is calculated based on ISO 14067 and has been certified by a third party and this will be extended to a wider range of high-capacity power relays. The G9KB-E is a high-capacity version of the G9KB series, which has the same size and weight as the G9KB reference model, but with a maximum opening and closing voltage of 800 V DC and a maximum current of 100 A. The rated value of 800 V DC 50 A and 600 V DC 100 A is especially suitable for 15~40 kW class battery related applications such as power storage systems and EV charger/V2X.
