Omron expands compact power relay range with improved high inrush variant
Omron has launched the G5Q-HR, the latest addition to the G5Q family of 10A PCB power relays. The new relays can achieve reduced power consumption and heat, and are 45 percent smaller than equivalent 16A relays. For applications which require high inrush current such as lighting controllers, smart plugs, home appliances and power supplies, this can contribute to downsized equipment design, while opening up new printed circuit board configurations.
First launched in 2001, the G5Q series has sold more than 500 million units worldwide. Considered one of the industry’s leading compact power relay products, the G5Q portfolio now boasts a wide range of variants covering many diverse applications, from home appliances to industrial motor loads. In response to customer demand for compact design and improved energy performance for 10A applications, Omron has now expanded its high inrush offering with the addition of the G5Q-HR, which is available in both single stable and latching variants.
As the only device in the G5Q portfolio that meets the TV-8 standard at 10A class, the G5Q-HR compliments the existing high inrush offering, while offering new possibilities for more powerful and compact end product applications. At 20.3 mm (L) x 10.3 mm (W) x 15.8 mm (H), it is Omron’s smallest TV-8 product.
The G5Q-HR is compatible with a wide range of capacitive loads as well as ramp loads of up to AC 120V, Inrush 117A. In accordance with its TV-8 certification, the G5Q-HR has been rigorously tested to last a minimum of 25,000 cycles, ensuring maximum longevity and reliability. The device also meets the UL Electronic Ballast Rating at 3A 277VAC and 5A 277VAC over 6,000 cycles, and meets IEC60669-1 at 3A 250VAC over 5,000 cycles. The G5Q-HR achieves a high inrush current resistance and supports multiple inrush loads. It is compliant with high input load standards exceeding 100A, such as lighting and power supplies.
The latching type (G5Q—U/K-HR) variant achieves extremely low power consumption by maintaining the contact “on” state with only one pulse of current. This reduces coil power consumption by approximately 99.9 percent compared to standard single-side stable relays. As well as reducing the power consumption of the relay itself, this can also help to reduce the amount of heat generated, contributing to greater efficiency and longevity of related components and systems.
