# If 200V is applied to the AC100V terminal, what will happen?

Last Updated: September 19, 2018When the G3PX turns ON and a load current flows, a residual voltage is produced on the switching element.

The heating value will be obtained from the following formula.

Example:

Case of the G3PX-220EUN (with rated currents of 20A)

VRMS (residual voltage)=1.6V (output ON voltage drop in the brochure)

If the power consumption is indicated as P:

P=20Aร1.6V

P=32W

This is the power consumption of the G3PX.

In terms of calorie 1cal/s equals 4.19W, therefore:

32Wรท4.19 โ approx.7.6cal/s

The residual voltage means the voltage lost inside the semiconductor when it turns ON.
