Description

ZVT2-50-IF 50A Flicker-Inhibited Temperature Controller

The ZVT2-50-IF is a microprocessor-based, closed-loop temperature controller engineered for precise control of high-power single-phase resistive heating loads. Using burst-fire control with flicker inhibition, it delivers smooth power regulation while minimising RFI and mains flicker—ideal for sensitive industrial environments.

Housed in a durable, panel-mount enclosure with an integral heatsink and built-in high-speed semiconductor fuses, this unit is designed for long-term reliability in high ambient temperatures. It is supplied complete with a control knob and clearly scaled 0–40°C dial for simple and accurate operation.
