Feature:1. Better Visual Experience: Color LCD HD display, 178 wide viewing angle, no dead angle, with backlight function, this AC power meter single phase can be clearly seen no matter day or night.2. ABS Material: This single phase power consumption meter is made of ABS flame retardant material and sensitive chip to ensure the safety of use.3. 6 in 1: The DIN rail digital multifunction meter is a meter that displays 6 parameters such as AC voltage, AC current, active power, power factor, frequency, and electrical energy on the meter.4. Easy to Use: If you need to reset the meter measurement (when measuring from zero), long press the RESET button on the right side of the meter panel for 5 seconds until the meter displays 0, then release the button, at which time the meter starts measuring from zero.5. Auto Save Data Function: When the measurement voltage is disconnected or power failure, the meter will automatically save the current test data, when reconnecting the measurement power supply, the meter will continue to accumulate on the original saved data.6. Wide Applications: Suitable for industry, power plants, automation equipment, DOS systems, electromechanical equipment, etc.Specification:Specifications:Type: External transformer Model: D52-2066Material: ABSMeasurement Accuracy: 1%2 wordsAlternating Current: AC 0-100A, current display resolution is 0.01APower Frequency: 45.0Hz-65.0HzPower Fator: 0.00-1.00PFActive Power: Measuring range is 0-45000W, the display resolution between 0-9999.9W is 0.1W, the rest is 1WElectricity: Measurement range is 0-99999kwh, 0-999.99kwh minimum display resolution is 0.01kwhMeasuring Speed: About 2 times per secondMounting Method: Rail typeItem Size: 80 * 54 * 64mm / 3.15 * 2.12 * 2.51inItem Weight: 122g / 4.30ozPackage Weight: 143g / 5.04ozPackage Size: 9 * 7 * 6cm / 3.54 * 2.75 * 2.36in.Package List:Package List:1 * Watt-Hour Meter1 * User Manual (English)
