Description

The SSRQ electronic relay is an electronic module with a built-in powerful triac controlled at the “zero” point and is designed to switch single-phase powerful AC loads. Due to the absence of moving parts, vibration and contact wear, the life and reliability of the SSR module is greater than that of electromechanical relays. Thanks to the special Snubberless ™ triak technology, SSRQ can switch both active and inductive loads up to 16 A at up to 400 VAC. The control signal is optically separated from the output and can be DC or AC voltage.
