The WSZ14DRS-32AWSZ12DM-32A is a single phase two wire smart energy meter with white back-lighted screen for perfect reading.It measures voltage,current,frequency,power,active energy,etc.One communication port(RS485 Modbus/M-bus)are provided for remote monitoring and setting,suitable for monitoring energy consumption in residental,EV Charging system,industrial andutility applications. With modular design,the energy meter has achieved as 1-Din(1module 18mm width)structure with the advantages of small size, high accuracy,high reliability and easy installation.The energy meter has been MID approved to meet the requirements of EU Directive 2014/32/EU.MID Certificate number is 0120/SGS⁰207.
◎ RS485 Modbus/M-bus communication ◎ Din-rail mounting,1 Module 18mm Width ◎ LCD with backlight ◎ Multi-measurement:kWh,W,V,A,Hz,etc ◎ With supper capacitor,the LCD is also legible twice within a period of 2 weeks without power supply. ◎ When the phase conductor is missing or the current direction is wrong ‘false’and the corresponding phase conductor are indicated on the display.
