Product Overview
This three-phase electronic active energy meter is designed for precise AC energy measurement in power utilities, factories, enterprises, commercial installations, and agricultural power systems. It uses a dedicated large-scale integrated circuit, 16-bit A/D conversion, digital multiplication, digital sampling processing, and SMT manufacturing technology to deliver stable and reliable metering performance.
The product supports three-phase active energy measurement at 50Hz and uses a clear LCD display for convenient on-site reading. According to the supplied specification, it can accurately measure forward and reverse active energy, while offering strong electromagnetic interference resistance, low power consumption, anti-tamper performance, wide load range, and long service life.
Key Features
- Three-phase active energy measurement for utility, industrial, commercial, and agricultural applications.
- Supports bidirectional active energy metering with accurate and stable digital processing.
- LCD energy display provides clear readings for inspection and billing support.
- One-phase or two-phase power loss does not affect measurement accuracy under three-phase supply conditions.
- Low power consumption, good electromagnetic interference resistance, and anti-tamper design.
- Optically isolated passive pulse output supports external metering and data acquisition.
- Three LED phase indicators help identify A, B, and C phase loss conditions.
- Designed in line with GB/T 17215.321-2008 and IEC 61036:2000 reference standards.
