LN Series

The LN Series of panel mounted Solid State Relays offer reliable back-to-back SCR switching up to 75 Amps at 528 VAC, coupled with a patented trigger circuit design which allows the SSR to switch resistive loads with minimal electromagnetic noise generated, ideal for use in commercial, residential and medical applications.

UL recognized and TUV certified, the LN series offers superior performance in applications that demand reliable switching and low emitted noise.

Additional features include:

Rating up to 75A @48-528 VAC
Zero Voltage Turn-On Switching
Conformance with IEC60947-4-3 Environment B for low voltage domestic, commercial and light industrial locations/installations
Patented Low Noise trigger circuit
IP20 touch-safe housing is available
Built-in Input/Output over-voltage protection
LED Input Status Indicator
3500 VAC Optical isolation
EMC Compliant to level III
