Many buyers are response:
Why test data is wrong? Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?
Answer: There are three types of power:
Active Power (P represents / unit W)
Reactive power (Q represents / unit Var)
Apparent power (S represents / unit VA)
Here that We only talk about Active Power, others please google it:
P = U * I * cosφ, cosφ it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time, P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.) P<U*I, As for how much to keep the power factor related to the specific, Different for each appliance power factor.
Note:
1. This module is suitable for indoor, not outdoor use.
2. applied load can not exceed the rated power.
3. The wiring order can not be wrong.
