Gefran - GTS-25/48-D-0 - 25A 480V AC Solid State Relay

The Gefran GTS-25/48-D-0 is a single-phase solid state relay (SSR) designed for industrial applications requiring reliable and rapid switching of AC loads. With a rated current of 25A and a maximum load voltage of 480V AC, this relay is suitable for controlling resistive and inductive loads. It features zero-crossing switching, which minimizes electrical noise and extends the lifespan of connected equipment. The relay is equipped with an integrated heatsink for efficient thermal management and is designed for DIN rail mounting, facilitating easy installation in control panels.  

Key Features:

• Zero-Crossing Switching: Ensures that the relay switches at the point where the AC voltage crosses zero, reducing electromagnetic interference and electrical noise.

• Integrated Heatsink: Provides effective heat dissipation, allowing the relay to operate at full rated current without external cooling.

• DIN Rail Mounting: Simplifies installation and integration into standard industrial control panels. 

• LED Status Indicator: Offers a visual indication of the relay’s operational status, aiding in troubleshooting and maintenance.

• Built-in Protection: Includes metal oxide varistor (MOV) protection to safeguard against voltage transients and surges.
