"EM513082/83/84" series meters are designed for DIN-Rail installation, suitable for grid-connected PV solar energy metering projects and EV charging metering solutions, the meters can measure and display various important power parameters, and can be connected through the RS485 communication port Real-time reading of meter data, the meter has passed MID approval, bi-directional energy metering makes this meter an excellent choice for solar energy metering.

Product Details

1.Brief Introduction

Three-phase Net Meter for V2G enabled charging stations of electric vehicles, Vehicle-to-Grid (V2G) technology has emerged as an effective solution to support the grid that operates EV in charging and discharging mode. V2G establishment involves three elements amongst the bidirectional metering plays a significant role. This paper aims to design and develop a cost-effective three-phase Net Meter. It allows the bi-directional flow of current and generate bills at an associated subsidize rates.

2.Key Features

Advanced design: this three-phase meter can be easily and securely snapped onto a 35 mm DIN rail. with low power consumption, high accuracy and good reliability. The small size, light weight and beautiful and safe design make it a good choice for testing the electrical 3 phase values.
3-phase electricity meter, not just an energy meter: press the M button. The three-phase counter can display active/reactive energy, three-phase voltage, current, positive/negative active power, power factor, frequency and other information
【With Blue LCD Backlight】The rated voltage is 3 x 230V/400V, 50/60Hz, the power consumption is <2W/10VA per phase, accuracy of class 1. 15 seconds until the LCD backlight is energy-saving and clearly visible.
Auto save: The meter reading is retained even in the event of a power failure. The values cannot be reset.
Easy to install and widely used: can be easily and securely snapped onto a DIN rail. AC watt meter DIN rail can be used for energy saving testing in offices, industrial electricity, hospitals, schools, apartments and shopping malls, etc
