SSR-120A Solid State Relay (DA)

Description

The Kampa HHG1 series DC-to-DC solid state relay (SSR) is a high-performance, contactless switching device designed for reliable control of DC loads. With a 40A current rating and wide operating range, it is ideal for industrial automation, power distribution, and DC system control applications.

Key Features:

DC-to-DC Switching: Specifically designed for DC load control, with 12–250VDC output range and 40A continuous current rating.
Wide Control Voltage: 5–32VDC input, compatible with PLCs, microcontrollers, and standard DC control circuits.
Contactless Operation: No moving parts or mechanical contacts, eliminating arcing, noise, and wear for long service life.
Transparent Cover Design: Clear protective cover shields terminals while allowing visual inspection of wiring status.
DIN Rail Mount: Standard package with screw terminals for easy installation in control panels.
High Reliability: Built for fast switching speeds and resistance to vibration, shock, and electromagnetic interference.

Applications:

DC motor control and soft-start systems
Industrial heating and temperature control (DC-powered elements)
Power distribution and battery charging systems
Automation equipment and PLC-controlled circuits
