The BSSRP solid state relay is a zero-cross operating electronic module designed to switch single-phase AC power loads. Thanks to its higher switching frequency and practically complete absence of electromagnetic interference, the SSR module is a non-contact and convenient substitute of power contact relays. The life and reliability of the SSR module, compared to these of the contact relays, are much higher because there are no moving parts, noise, shocks, and vibration during the operation. BSSRP can switch active or small inductive loads from 10 to 40 A at power voltage up to 275 VAC. The control input is optically isolated from the output and accepts AC or DC voltage signals. An operating LED indicates ON/OFF device status. Heatsinks are available as accessory.
