If you need only the CT, please check this: >>> Here 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.
