Product Introduction

This single-phase two-wire AC active energy meter is designed for residential, utility, and industrial applications. It offers long service life with high stability, excellent overload capability, low power loss, and a compact form factor. The meter features a 6+1 LCD display for clear energy readouts and supports bidirectional total active energy measurement, with reverse active energy accumulated into the total. Energy data is retained in the memory chip for over 15 years after power failure. Visual indicators include power-on and reverse LEDs, while a pulse LED provides real-time operational status. The meter also includes a passive pulse output with optical coupling isolation for external monitoring. With flexible installation options—35mm DIN rail or wall mounting—this meter delivers reliable and accurate energy measurement for a wide range of applications.
