The meter fully complies with the relevant technical requirements for class 1 single-phase active energy meters in the international standard IEC 62053-21. It can accurately and directly measure 50Hz or 60Hz active power consumption in single-phase AC network. It has the characteristics of good reliability, small size, light weight, good looking and easy to install. Features and Specifications Standard 35mm DIN rail mounting in accordance with DIN EN50022. Bipolar width (17.5 mm module), conforming to DIN43880. Standard configuration 5+1 backlit LCD display (99999.1KWh). Function: display of electricity, voltage, current, frequency, power factor. The LED supplies the signal (red) for the pulse of energy. One-way measurement of single-phase two-wire active power consumption. It has nothing to do with load current flow. Comply with GB/T17245.321-2008. For direct connection operation, two wiring methods can be selected. Standard configuration S-type wiring, optional U-type wiring. DD15SD series: direct connection, high and low input and output, high and low input and output, can be installed, S-type wiring of standard configuration. DDM15SD series: integrated end cover, beautiful and elegant, protect the safety of the use of electricity.
