Overview of RXDC-3 On-Load Winding Temperature Rise Tester:

Main applications:  Measures temperature rise in coils of motors, compressors, transformers, etc.,

supporting on-load temperature rise testing.  It measures cold resistance using the four-wire method and

calculates the real-time temperature rise under load using a built-in algorithm. This method is more accurate and

effective than traditional thermocouple methods and does not damage the sample. Supports both frequency-controlled

and fixed-frequency compressor temperature rise testing.

(Available in single-channel and dual-channel versions; single-channel tests one winding, dual-channel tests both

primary and secondary windings simultaneously)
