AC 80-260V 100A LCD Display Digital Panel (Current, Voltage, Power & Energy) Meter.

This meter can only be used with one-phase AC power. And it can only measure the active power (real power consumed from your load). It doesn't show apparent power (For more information about the difference, please search AC POWER on Wikipedia). 

• The meter can only measure the active power (real power) , It doesn't show apparent power.
• Overload alarm threshold preset function (can set power alarm threshold)
• Voltage test range: One-Phase 80~260V AC Power, 50/60HZ; Current test range: 0~100A;
• Store energy data when power off (can be reset).
• Large-screen LCD (display voltage, current, active power, and energy at the same time).
• The blue backlight can be turned on/off manually. The CT can be either on Live line or Neutral Line.

Precautions 

1. Please make sure the AC input is a Pure Sine Wave.(Municipal electric power is pure sine wave). Please don't use the meter to measure AC power converted from a DC-AC inverter UNLESS you can make sure the output from your DC-AC inverter is Pure Sine Wave. This is very importatnt.
2.  Applied load should not exceed the rated power.
3. Wiring order can not be wrong.
4. This module is suitable for indoor, please do not use outdoor.
