            G9KA High Power PCB AC Relay
                    Omron's G9KA relay supports high current applications with high capacity load ratings
    

Omron's SPST-NO relay supports high current applications with high capacity load ratings. The high capacity and low contact resistance characteristics make the G9KA ideal for PV inverters/power conditioners and industrial inverters, as well as UPS systems. This 200 A high power relay reduces the necessity for complex temperature designs and inclusion of heat transfer devices due to low contact resistance compared to similar relays. It can support designs with high voltage requirements of up to 800 V_AC.

Features and Benefits

800 V_AC; 50 A switch on, 200 A carry current, 50 A switch off at +85°C (30,000 ops N.O.)

Capable of supporting high capacity switching and carry currents

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

Reduces power consumption to 1 W from 5 W when held at 45% of rated V

Low initial contact resistance (0.2 mΩ max)

Reduces heat generation due to contact resistance
Lower heat generation results in a lesser need for materials such as heat sinks

Applications

Power conditioner inverter
Industrial inverter

Uninterruptable power supply (UPS)
High voltage designs

Dimensions and PCB Layout

Power Saving Due to 45% to 60% Holding Voltage

Precautions for G9KA Use

Do not connect to individual relays by probes or by socket; abnormal heat may be experienced by insufficient connections
Install and use relays with the recommended soldering conditions; avoiding recommendations may also lead to abnormal heat generation
Do not use dropped relays as the shock may cause improper relay operation
