Multifunctional AC40-300V 100A AC Voltage and Current Meter with Color LCD Digital Display Power Monitor

General Description: The multifunctional AC40-300V 100A voltage and current meter is a digital power monitor with a high-definition color LCD screen. It allows simultaneous display of AC voltage, AC current, active power, electricity quantity, and electrical energy measured. With a wide 178° viewing angle, this device is designed for easy and efficient use. Technical Specifications: Measurement Accuracy: 1% ± 2 digits; Measurement Range: AC Voltage: AC 40.0-300.0 V; AC Current: AC 0-99.99 A (display resolution: 0.01 A, maximum display: 100.0 A); Active Power: 40-300 V, display range 0-30,000 W, 200-450 V, display range 0-45,000 W (display resolution: 0.1 W between 0 and 9,999.9 W, 1 W above); Power: Display Range: 0-10,000 kWh (displays 9,999.99 kWh, above 10 kWh displays 0,000.99 kWh, maximum display 9999999 kWh) Measurement speed: 2 times per second Dimensions: 79*43*48 mm Installation size: 76*39 mm Backup/memory function: retains data in case of power failure Transformer hole diameter: 15.5 mm Secondary conductor wire: extension possible from 0.5 to 3.5 meters Installation Connect the secondary end (green wire) of the current transformer to the blue terminal of the instrument. Pass the measuring loop wire through the central round hole of the current transformer. Connect the voltage measuring cable to the green terminal of the meter. Press the reset button for 5 seconds to reset the accumulated power value. Operation Once the device is powered on, the instrument displays the measured value. To measure mains voltage, check the appropriate voltage range (40-300 V AC or 200-450 V AC). Avoid incorrectly connecting the Voltage input terminals and current transformer to prevent damage to the instrument. Other information
