Solid state and PhotoMOSFET relays for extreme efficiency

Solid state relays (SSR) allow you to control high-current AC loads from lower voltage DC control circuitry. Solid state relays have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there is no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.​

 

A MOSFET relay offers superior performance to an electromechanical relay in many applications. It is a solid-state device that replaces a coil-activated mechanical switch with an optically isolated input stage driving a MOSFET. Internally, a MOSFET relay includes an input-side LED and an output side with a photodiode dome array (PDA), a control circuit, and an output FET block.​

 

Our main partners for solid state relays and PhotoMOSFET relays are internationally acknowledged manufacturers i-Autoc (Xiamen Kudom) and Bright TOWARD (Taiwan).
