Product Description

    Intelligent Dry-Type Transformer Monitor is designed for the safe operation of dry-type transformer. It can automatically operates the fan's relay according to the temperature. By comparing the current temperature to a pre-selected temperature, the monitor operates an alarm and the relay trips to keep the transformer running safely.
