Product Description
The DC thermal stability tester is applicable for the thermal stability test of SPDs. It is for indoor operation. One DC power source with a constant current between 2mA ~5A is applied on the SPD. The current through the SPD and the surface temperature of the SPD are continuously monitored to check if it reaches thermal equilibrium, and the disconnectors act.
