G9KA-1A DC12 BY OMZ

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

Features & Benefits

• 800 VAC; 50 A switch on, 200 A carry current, 50 A switch off at 85°C (30,000 Ops N.O.)
• Low Initial Contact Resistance (0.2mΩ max)
• Holding Voltage Required is 45-60% of Rated Voltage
• Capable of supporting high capacity switching and carry currents
• Reduces heat generation due to contact resistance
• Lower heat generation results in a lesser need for materials such as heat sinks
• Reduces power consumption to 1W from 5W, when held at 45% of rated V

Applications

• Power conditioner systems
• UPS
• PV inverters
• Industrial inverters
