DTS866 type DIN rail mounted three-phase four-wire electronic watthour meter line I microelectronics technology with a dedicated LSI, the sampling process of the application of digital technology and SMT process research and development of advanced technologies such as three-phase four-wire energy meters . The technical performance of the table in full compliance with the technical requirements of a three-phase active energy in the international standard IEC 62053-21, directly and accurately measure the rated frequency of 50Hz or 60Hz three-phase, four-wire AC grid load active energy consumption. The table by the stepper motor pulse counter function of power, has good reliability, small size, light weight, beautiful appearance, easy installation. Standard 35mm DIN rail mounting to DIN EN 50022 standard, or in front of the board installed (mounting holes center distance 63 mm), users can choose any of two installation methods. ● 10 pole width (Modulus 12.5mm), complying GB/T7121-1993 standard. ● 7 digit LCD display. ● equipped with a the polarity of passive close-energy pulse output port is compliant with IEC 62053-31 and DIN 43864 standard. ● 5-LED indication per phase power status and close electrical energy pulse signal and power telecontrol pulse signal. ● automatically detect the load current direction of the trend, and instructions (work close energy pulse signal indicating the green, on behalf of the current reverse). ● Single direction three components measure three phase four wire active energy consumption, independent of the load current direction of the trend, according to IEC 62053-21 standard. ● Choose two components measuring active energy of three-phase three-wire or two-phase three-wire active energy ● Standard configuration type S wiring (Inlet from bottom, outlet from top) for direct connect use option 5 +1 bit pulse counter display, CT access-use and PT & CT access type sales hotline :0577 -6,298,677,113,757,772,139 Contact: Zhu micro
