Din Rail 3 Phase Energy Meter

Brief Introduction

DTZ1737 is a din rail 3 phase 4 wire smart energy meter with 1~4 channel, designed with advanced energy metering chip and SMT technology. With RS485 port, the meter can communicate with the computer to exchange the data. This 3 phase 4 wire smart energy meter can be widely applied in industrial and commercial field.

Main Functions

1. Supporting 1~4 loop metering function.

2. Each loop meter has import/export active and combined active data.

3. Each channel meter can measure the current, voltage, frequency, power factor, active power, reactive power, apparent power.

4. Can record and alarm of undervoltage, overvoltage, supervoltage and phase loss events.

5. On the meter reading day of every month, the electric quantity will be settled automatically.

6. Timed data freeze, hourly data freeze and daily data freeze. Meter can freeze data of energy, etc. There are 30 timed freeze, 254 hourly freeze, 62 daily freeze.

7. LCD digital display, rotate display energy meter parameters.

8. The data inside the meter can be read through the RS485 and infrared interface.

9. The electricity meter is installed with standard 35mm din rail.
