ZVT1-25-IF: 25A Burst Fired Temperature Controller for 110V Heating Systems

The ZVT1-25-IF (0–40°C, 110V) is a compact, high-accuracy temperature controller designed for low-voltage heating applications requiring precise thermal management. With burst fire zero-cross switching and flicker inhibition, it provides smooth, proportional temperature control without introducing electrical interference. The 25A capacity, durable heatsink, and microprocessor regulation make it an excellent solution for 110V heating and environmental systems.

⚠️ Note: The temperature sensor (NTC type) is ordered separately and must be properly earthed for safe operation.
