Product Description:
The SO8 series relays are Celduc's premier range of single-phase panel mount solid state relays. Housed in an IP20 touch-safe package with removable flaps over both the input and output terminals, the SO843970 solid-state relay is capable of switching 35 amp resistive and inductive loads at line voltages between 12Vac and 275Vac. Designed for endurance and reliability in harsh industrial applications, the SO843970 utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads. This significantly reduces the total power dissipation of the SO843970 in comparison to similar triac output solid state relays, in addition to enhancing the relay’s ability to withstand heavy surge currents.
Over voltage protection is standard on both the input and output circuit of the SO843970. A green LED provides visual indication that the input/control signal is applied to the relay.
Typical applications for the SO843970 solid state relay include; resistive heating, motor control and inductive applications with a power factor ≥0.5.
A heat sink and thermal compound are normally required to prevent a solid state relay from overheating during normal operation. HBControls offers a wide range of thermally efficient, DIN and panel mount heat sinks suitable for use with Celduc solid-state relays.
