Application

Thermal stability test equipment is mainly used to apply DC supply between constant current 2mA~20A for SPD and varistors through continuously monitoring the current and surface temperature. The equipment can check whether it reaches thermal equilibrium and the disconnector is in operation or not.

Standard

IEC61643.1-2005, GB18802.1-2011

Advantages and Features

1. The voltage and current value and real-time curve are displayed automatically on the computer interface.
2. Automatic product test
3. High accuracy
4. K-series electrical coupling measures the temperature precisely
5. High voltage protection: red and green lights indicating the status, scramming button, the door interlock.
6. Plexiglass covering and safety interlock on the test area
7. Over current protection on the main loop
8. The casting of control cabinet is grounding and test circuit always grounds at one end.
