Elotek SSR – DIN-Rail Heatsink Solid State Relay
25 A single-phase, zero-cross, varistor-protected SSR for plastic injection temperature control.
- 25 A load current
- Zero-cross switching
- Varistor surge protection
- LED status indicator
About the product
Developed by Elotek with 100% local production, this DIN-rail heatsink 25 A single-phase solid state relay is a high-performance switching solution for temperature control in plastic injection systems. It switches 24–240 V AC loads at zero crossing from a 5–30 V AC/DC input; an LED status indicator and varistor surge protection keep your equipment safe. It can also be applied to three-phase loads.
Key features
- Robust build, large heatsink and reliability for applications requiring precise temperature management.
- Operates from a 5–30 V AC/DC input; handles 24–240 V AC load voltage.
- Zero-cross AC load switching for precise, stable temperature control.
- LED indicators for easy monitoring of relay status.
- Varistor protection against voltage peaks.
- Applicable to three-phase loads.
- DIN-rail mounting; easy integration into injection machine panels.

Frequently asked questions
Is this the same relay used in EHRTC controllers?
Yes. It is the same product family as the 25 A solid state relay in the EHRTC-PM1 external power stage and is available as a spare part.
Why does zero-cross switching matter?
The load is switched at the zero point of the mains voltage, which reduces electrical noise and inrush stress on the heater; control is more stable and heater life is longer.
