Temperature Rise Tester for Transformer Live Winding

The LSTMR-103 Temperature Rise Tester for Transformer Live Winding is an important instrument for measuring the performance of small power motors and electronic transformers. It is a live winding temperature rise measuring instrument for windings of motors, compressors, etc. used in various household appliances (such as air conditioners, refrigerators, freezers, electric fans, range hoods, etc.). LSTMR-103 is also suitable for measuring the winding temperature rise of electronic transformers such as power transformers, AC/DC converters (ADAPT), AC/AC, AC/DC, chargers, etc. under 50Hz/60Hz conditions, and has complete functions.

Winding temperature rise is an important indicator for measuring the performance of small power motors and electronic transformers. According to the national and international standards for small power motors and transformers, small power motors are required to accurately measure the temperature rise under rated load or stall conditions; while for electronic transformers, not only the temperature rise under rated load or stall conditions is required to be accurately measured, but also the temperature rise under secondary short circuit or overload conditions is required to be measured.

Specification:
• The color LCD screen can display the cold resistance, hot resistance, temperature rise, and temperature rise test time of two groups of windings. You can select one group of windings or two groups of windings to detect the temperature rise at the same time.
• Automatic range switching, wide linear range, good reading repeatability, stable performance.
• Equipped with RS232/485 interface, connected to the computer, read and save the measurement data, so as to facilitate the tracking of original data and quality statistical analysis.
• You can set the U disk storage time, store data in the U disk at a fixed time.

Typical application of LSTMR-103 Temperature Rise Tester:
i. Applicable to the temperature rise measurement of windings of motors, water pumps, compressors, small power motors, etc. for various household appliances (such as air conditioners, refrigerators, freezers, electric fans, range hoods, etc.).
ii. Applicable to the research and development, quality control and temperature rise life test of electronic transformers such as power transformers, AC/DC converters (ADAPT), AC/AC, AC/DC, chargers, etc. under 50/60Hz conditions
