Celduc SK Series Solid State Relay PCB Mount, 4 A Load, 275 V AC Load, 30 V DC Control SKA20420

Celduc SKA20420 Solid State Relay series is a PCB-mount vertical type relay designed for industrial and automation applications. It supports a maximum load current of 4 amperes with AC load voltages up to 275 volts and DC control voltages ranging from 4 to 30 volts. The relay features a triac output, zero cross switching function which reduces interference and enhances durability by minimizing switching stresses.

This relay is constructed with a PCB terminal type mount, having compact dimensions of 43.2 mm in length, 22.5 mm in width, and 25 mm in height. It provides high immunity to external interference and operates reliably over a temperature range from -40°C to 80°C, with an IP20 ingress protection rating.

The device exhibits an extremely low off-state leakage current of 0.1 mA and a low on-state resistance of 40 milliohms, contributing to efficient circuit operation. It is certified for use as a component in Canada, meeting stringent quality and safety standards.

These features make the SKA20420 relay an excellent choice for applications in industrial machinery, automation systems, electrical panels, HVAC controls, and manufacturing equipment where precise and reliable solid state switching is required.

The relay supports a maximum load current of 4 amperes for moderate power switching. It is designed for PCB mounting with standardized terminal connections for easy integration. Zero cross switching function minimizes electrical noise and prolongs relay life.

Wide operating temperature range from -40°C to 80°C ensures flexibility in harsh environments. Compact dimensions facilitate use in space-limited control circuit designs. Low off-state leakage current improves system efficiency by reducing power loss.

Certified for Canada, assuring compliance with relevant industrial standards. Triac output allows control of AC loads with enhanced switching stability. Explore more products in the Electronics & Electricals category under Relays & Contactors at EnvMart for reliable industrial automation solutions.
