100 AC Digital LED Power Panel Meter Monitor Power Energy Voltmeter Ammeter

100 AC Digital LED Power Panel Meter Monitor Power Energy Voltmeter Ammeter Introduction: Active power is calculated as: P = U I cos; cos represents the power factor; purely resistive loads (such as incandescent; heater; etc.) the power factor is generally close to 1; inductive and capacitive load load power factor 0-1; therefore purely resistive load test time; P is substantially equal to or close to U I; test inductive or capacitive loads (such as refrigerators; washing machines; televisions; computers; etc.) when; P Less than U I As for the specific number to keep the power factor related to power factor different for each appliance; please show table prevail. Specification: Size: 90x50x25mm Apply to power grid voltage range: 110V-220V Working Voltage: 80 ~ 260VAC Test voltage: 80 ~ 260VAC Rated Power: 100A /22000W Working Frequency: 45-65Hz Measurement Accuracy 1.0 Feature: Network voltage direct power supply; no external power supply; measurement precision; large-screen LCD liquid crystal screen display clearly. Function 1. Electrical parameter measurement function (voltage; current; active power; power). 2. Overload alarm function (over power alarm threshold; the backlight and power flicker tips). 3. The power alarm threshold preset function (can set up their own power alarm threshold). The power button clear function. 5. Power-down data storage function. 6. Large-screen LCD screen full display function (display voltage; current; active power; power). 7. Backlight. B. display and key Display Interface Display voltage; current; power; energy parameters from the large-screen LCD screen simultaneously.
