Product Description

Product Description

Dry Type Transformer Temperature Controller

A dry-type transformer temperature controller is a critical device designed to monitor and regulate the temperature of dry-type transformers, ensuring their safe and reliable operation.

Based on the input measurement data and various preset control parameters, the single-chip microcomputer performs calculation and processing, thereby displaying the winding temperature value and outputting corresponding control signals to realize functions such as cooling fan start-stop control, over-temperature alarm, and tripping protection.
