            G9KB Series High Power PCB DC Relay
                    Omron's G9KB series supports high current applications with high capacity load ratings
    

Omron's G9KB and G9KB-E series SPST-NO relays support high current applications with high capacity load ratings. The relay's high capacity characteristics make the G9KB and G9KB-E relays ideal for energy storage systems, power conditioning, and electric vehicle charging applications. This product can switch up to 100 A at 600 V_DC or 50 A at 800 V_DC bidirectionally, eliminating the need for multiple switching components to alternate forward and reverse currents. The G9KB family has been developed with high-performing arc cut-off technology to combat contact arcing typical with large DC power applications.

G9KB - Features and Benefits

50 A at 600 V_DC (2,000 operations)

Capable of supporting high capacity DC loads

Holding voltage required is 45% to 60% of rated voltage

Reduces power consumption to 560 mW from 3.4 W when held at 45% of rated V

Bidirectional switching with arc cut-off

Eliminates the need for two relays in the case of DC forward/reverse currents
Swift extinguishing of arc provides a safer switching of high DC voltage loads

G9KB-E - Features and Benefits

100 A at 600 V_DC (100 operations) UL certified
