Relays for High Power Applications

Series ST - Teledyne Relays

Series ST relays are designed for high-power applications. The design incorporates an SCR or triac output. The relays utilize optical isolation to protect the control from load transients. A control LED is available on certain models. Internal MOV is also available on ST24D 25A and 50A models.​ All Series ST relays are Zero-Cross switching.

Available options include:
ST24D12 12A, 12-280Vrms, 600Vpeak Load; 4-30Vdc Control​
ST24D25 25A, 12-280Vrms, 600Vpeak Load; 4-30Vdc Control
ST48D50 50A, 24-600Vrms, 1200Vpeak Load; 5-30Vdc Control
