DescriptionAs a single-phase configuration electric energy meter suitable for AC low-voltage system, our Single Phase Din Rail Kwh Meter can complete the installation work with the guide rail, and the loading and unloading is very easy. It is widely used in residential buildings, commercial buildings, distribution boxes and other facilities. It has an energy pulse output function for remote monitoring, which can identify all precise changes in current with a level of 1.0 accuracy, find the most energy-efficient solution and automatically adjust it. So it can be used to monitor power consumption in each department, unit or workshop and manage electrical installations for building management. FeaturesOur Single Phase Din Rail Kwh Meters provide sensitive and accurate testing of voltage, current, power and other power parameters. They are equipped with RS485 communication ports and have various control systems, SCADA systems and energy management systems built in to help you easily monitor, collect and manage current. They are also compact and take up very little space when installed so that you can quickly and easily complete the installation.

Check whether the wiring of the auxiliary power supply is consistent with the wiring diagram of the instrument, and whether the wiring is loose or falling off; 2. Use a multi-meter to measure whether the input voltage value of the auxiliary power supply is within the normal working voltage range of the instrument. Signal input failure鈼廎ailure performance: After the energy meter is powered on, the display power or energy count is not accurate. 鈼廡roubleshooting: 1. Switch the display interface of the energy meter to the power (active P, power factor 位) interface, check whether the power display is negative and whether the power factor is between 0.9-0.95, and then check whether the input and output of the current signal line are reversed ( That is, the incoming line of the current must be consistent with the incoming end of the instrument), And consistent with the wiring on the energy meter. Communication failure鈼廎ailure performance: After the energy meter is powered on, it cannot communicate with the host computer normally. 鈼廡roubleshooting: 1. The voltage value between the communication output A and B of the measuring instrument should be between +(4.4-4.5)V; 2. Check whether the communication wiring method is correctly wired according to the wiring diagram (that is, the communication terminal A/B of the instrument should correspond to the communication serial port A/B).
