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. Features ● 35mm DIN standard rail mounting, to DIN EN 50022 standard, or the front 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
