Product Overview
The Automatic High-Current Temperature Rise Test Equipment is a dedicated testing solution for evaluating the thermal performance of electrical equipment under high-current operating conditions.
The system combines a high-current AC/DC power source, digital measurement unit, temperature acquisition system and intelligent control functions to create a complete platform for temperature rise testing.
Product Advantages
- High-Current Loading Capability
The system delivers adjustable high current for electrical components that require substantial load conditions during thermal testing. The output can be regulated smoothly according to the requirements of the test specimen.
- Stable Test Conditions
A controlled current source helps maintain consistent loading throughout the test, providing a more reliable basis for evaluating temperature rise and thermal performance.
- Simultaneous Temperature Monitoring
Multiple temperature points can be monitored during one test. With configurations of 12, 24, 48 or 64 channels, engineers can track temperature distribution across different parts of the specimen.
- Automated Test Operation
The automatic control mode simplifies repetitive testing tasks such as current adjustment, timing, measurement and data recording.
- Digital Data Processing
Measured electrical and temperature data can be collected digitally and used to generate test curves and standardized reports.
- Protection Against Abnormal Conditions
Built-in overcurrent, overvoltage and overtemperature protection helps minimize risks caused by abnormal operating conditions.

FAQ
What is high-current temperature rise testing?
High-current temperature rise testing evaluates how much an electrical component heats up when subjected to a specified current for a defined period. It is commonly used to assess thermal performance, electrical connections and current-carrying capability.
Which products can be tested?
Typical test objects include circuit breakers, switchgear, contactors, thermal relays, motor protection devices, busbars, cables and other current-carrying electrical assemblies.
