OMRON G9KB Power Relay for Renewable Energy Systems

Main models

·G9KB-1A series: This series of relays may include multiple voltage versions, such as DC12V and DC24V, suitable for applications with different control voltage requirements.

·G9KB-E series: As a high-capacity version of the G9KB series, the G9KB-E series has higher open close voltage ratings and higher current ratings, such as a maximum switching voltage of 800V (DC) and a maximum switching current of 100A. It is particularly suitable for battery related applications ranging from 15KW to 40kW, including fixed power storage systems, uninterruptible power supplies (UPS), and fast chargers for electric vehicles (EV).

Technical features

1.High capacity bidirectional opening and closing

The G9KB series relays support bidirectional opening and closing of high voltage and high current, which can meet the complex and demanding power control requirements in power systems.

2.High quality materials

Made with high-quality materials to ensure the durability and long-term stability of the relay.

3.Low Contact Resistance

Realize low contact resistance, reduce energy loss when current passes through, and improve equipment efficiency.

4.Safety certification

We have obtained international safety certifications such as UL60947-4-1 and EN61810-10 to ensure the safety and reliability of our products.

5.Miniaturization design

Compared with unidirectional relays with equivalent performance, the circuit board area has been reduced by about 75%, and the coil power consumption has been reduced by about 60%, which helps to achieve miniaturization and lightweighting of the equipment.

6.Arc blocking technology

By configuring a permanent magnet near the contact to extend the length of the discharge arc generated between the relay contacts during DC current blocking, high-capacity DC current can be effectively and safely blocked.

7.3D arc simulation technology

By collaborating with industry institutions on 3D arc simulation technology, the speed and quality of design and technical inspection are improved. Through the visualization of arc phenomena, the efficiency of the internal arc blocking process of relays and the miniaturization of component bodies are achieved.
