Feature:1. STANDARD INSTALLATION: The single phase energy meter is mounted on a 35mm standard DIN rail, conforming to DIN EN50022. single pole width(modulus 18mm), conforming to DIN438802. LCD DISPLAY: Single phase din rail energy meter standard configuration 5+1 digit display(99999.1 KWH), by the stepper motor pulse counter display and LCD display3. WITH INDICATOR LIGHT: Digital single phase energy meter use two color LED indicator to indicate power status(green) and power pulse signal(red)4. AUTOMATIC DETECTION: Din rail power meter automatically detect the flow direction of the load current and indicate(only the red power pulse signal is working, if there is no green indicating power supply, this is the flow direction of the load current is opposite)5. MEASURING OBJECT: Din rail volt meter can measure active power, voltage, current, power, power factor, frequency and other data, useful and practicalSpecification:Item Type: Single Phase Energy MeterRated Voltage: 230VRated Current: 5(50)A.Package List:1 x Din Rail Meter1 x User Manual Have a great time shopping!
