Single-phase Two-wire Electronic LCD type super capacitor short long terminal cover Watt-hour Kilowatt hour kWh Meter
Single-phase Two-wire Electronic Watt-hour Meter/Kilowatt hour Meter
Product Overview
This single-phase two-wire electronic watt-hour meter adopts the advanced LSI circuit, SMT manufacturing technology, with high accuracy, good linearity, wide working voltage range and high reliability, low power consumption, wide load etc. Suitable for rated voltage 120V, rated frequency 50Hz(60Hz optional), measure single phase active energy of AC.
It is complying with the requirement of single phase energy meter of IEC62053-21/IEC62052-11 standard.
Function and Features
- 5 digits large easy-to-read display, the smallest error reading.
- This electronic energy meter adopts exclusive use LSI and advanced SMT surface fixing technique, simple structure and few periphery components, high reliability, do not need calibrate for long-term operation.
- With greatly improved dynamic working range of meter, making 10 multiple actual overload.
- With reverse direction metering function, when meter happens reverse current, the light of reverse direction will be turn on, if remove the reverse, the light will on turn off.
