Efficient PWM controlled power relays available now

11-06-2021 | Omron | Connectors, Switches & EMECH

Omron Electronic Components Europe has released PWM controlled versions of three of its most popular power relays, providing coil power levels 75-90% lower than similar standard versions.

Its G2RL, G5Q and G5NB relays are now offered in types supporting PWM of the coil holding current, decreasing the duty cycle and the average current. This reduces the power consumption and the heat developed in the relay, increasing efficiency and decreasing thermal load, particularly in applications where banks of relays are used.

The high capacity 16A G2RL-PW1, a low-profile power relay, only 15.7mm in height, provides a coil power consumption of just 120mW, compared to 400mW for the standard version. The SPDT G5Q-PW, a miniature power relay with a 10A switching capacity, offers a coil power consumption of only 36mW in PWM form, compared to 400mW for the standard version. The G5NB-PW, an efficient single-pole, 3A/5A relay with a 10kV impulse withstand voltage, provides the lowest coil power consumption of only 32mW, compared to an already efficient 200mW for the standard model. All three families are optionally available in IEC/EN 60335-1 conformant version.
