AC 20A/100A Digital Voltage Meters indicator Power Energy current Amps Volt wattmeter detector

Dear customers friends, please read our website carefully We have Two models of 20A and 100A When buy it please pay attention products model , so as not to buy wrong! Thank you Descrtion 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 hines, televisions, computers, etc.) when, P Le 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: 90x54.5x28mm Apply to power grid voltage range 110V-220V Working voltage: 85 ~ 250VAC Test voltage: 85 ~ 250VAC Rated power: 0-100A / 0-20000W OR 0-20A/0-4400W（Two products model ） 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. A. Function 1. electrical parameter measurement function (voltage, current, active power, power). 2. overload alarm function (over power alarm threshold, the balight and power flier ts). 3. The power alarm threshold preset function (can set up their own power alarm threshold). The power on clear function. 5. Power-down data storage function. 6. Large-screen LCD screen full display function (display voltage, current, active power, power). 7. Balight. B. display and key Display Interface Display voltage, current, power, energy parameters from the large-screen LCD screen simultaneously. Paing List
