ZVT2-25-IF: 25A Burst Fired Temperature Controller for Low-Temperature Systems

The ZVT2-25-IF (0–40°C, 230V) is a precision-engineered burst fired flicker inhibited temperature controller designed for high-accuracy temperature regulation in OEM and industrial heating systems. Capable of handling up to 25A at 230V, this controller ensures stable, proportional temperature control through zero-voltage switching, effectively minimising RFI and power flicker. Ideal for low-to-moderate temperature applications such as heating mats and environmental control systems, it delivers reliable performance in a compact, easy-to-install enclosure.

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