SDM320Y Single Phase Smart Modbus Remote Control Din Rail Prepayment Energy Meter

Product Overview

Description

 

SDM320Y prepaid energy meter is EASTRON’s latest model of single phase electronic prepaid energy meter. It is in full compliance with technical requirements of IEC62053-22 standard for Class 0.5S energy meter. It has a complete prepaid management system, which is convenient for power purchase. The system automatically deducts fees according to electricity consumption. Recharging operation can be done through network remotely, no need any medium such as IC card. The meter has two-level balance alarm function and an emergency amount function. It will automatically stop power supply when tenant in arrears or credit become zero or reaching the pre-set value and the real-time monitoring the look whether there is any abnormal situation.

The meter is with excellent reliability that can display remaining capacity, available remaining, total power consumption/ purchase of electricity, credit line, overdraft consumption, load threshold, pay model, voltage, current, active power, active energy, import energy, export energy, power factor and frequency. The reactive power, apparent power can be read by Modbus.
