Question
How much heating value flows from the Electrical Regulator "G3PX"?
Answer
When 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=20A×1.6V
P=32W
This is the power consumption of the G3PX.
In terms of calorie 1cal/s equals 4.19W, therefore:
32W÷4.19≒approx.7.6cal/s
The residual voltage means the voltage lost inside the semiconductor when it turns ON.
