RS237(DR1-1) Three phase din rail electronic energy meter is the newest smart type energy metering product developed by our company depending on high technology. It is designed and manufactured by adopting the latest integrated circuit technology at present, using the advanced software algoriyhm and conforming to the relevant international IEC standards. It has various functions,such as metering,control, alarm, display and communication, etc. It is with the small size, easy to be installed and connected with the grid for realizing the measuring of energy. It can be directly installed together with the air switch,circuit breaker and contactor,and it acts as the signal collection unit of the places that have the electric power split-phase managing needs, such as at factories, schools hospitals and shopping malls, etc.

General introduction:

RS237(DR1-1) Three phase din rail electronic energy meter is the newest smart type energy metering product developed by our company depending on high technology. It is designed and manufactured by adopting the latest integrated circuit technology at present, using the advanced software algoriyhm and conforming to the relevant international IEC standards. It has various functions,such as metering,control, alarm, display and communication, etc.

It is with the small size, easy to be installed and connected with the grid for realizing the measuring of energy. It can be directly installed together with the air switch,circuit breaker and contactor,and it acts as the signal collection unit of the places that have the electric power split-phase managing needs, such as at factories, schools hospitals and shopping malls, etc.

Main functions:

1. Measuring function: It can measure the positive and negative active and reactive energy and the time-sharing energy, and also can measure various parameters in real time, such as voltage,current,active power, reactive power,grid frequency and other parameters of each phase and combined phase.

2. Impulse output: It is with 2 standard passive energy impukse outputs, which is convenient for users to carry out the inspection and calibration.

3. Communication: It is with RS485 communication function, and the communication protocal is MODBUS-RTU and GB/T 19582-2008.
