Hoofddorp, Netherlands– Omron Electronic Components Europe has extended its AC relay portfolio. It will provide its highest ever current and voltage capacity for AC PCB relay. The new G9KA-E operates with voltage capacity up to 1000VAC, and current up to 300A. It is one of the highest specifications in the current PCB relay market.
Omron’s G9KA high-power relay series guarantees a mechanical lifetime of 100,000 operations. The ultra-low contact resistance of 0.2mOhm maximum minimises contact terminal heating allowing it to carry high current loads. The plunger-type relay structure provides high endurance and lower power consumption. Whilst well-designed terminals improve heat dissipation, further enhancing safety and longevity.
Applications include grid-tie inverters and uninterruptible power supplies. The G9KA series can be applied to inverters for photovoltaic and energy storage systems. Specifically, the G9KA-E is suitable for use in 200-400kVA / 600-800VAC inverters. Omron’s G9KA-E AC PCB relay is also ideal for UPS input and output lines, providing disconnect from the grid and the load. A particular advantage here is G9KA-E’s suitability for power supplies that incorporate 100-200kVA, 3-phase 400VAC input/output circuits.
Replacing conventional contactors in all applications, these new PCB high-power relays reduce system weight and size whilst enabling simpler manual or automated assembly.
