Item Type: Single Phase Meter <br>Rated Voltage: 230V <br>Rated Current: 10 (40) A <br>Frequency: 50Hz <br>Pulse Constant: 1000imp/kwh <br>Insulation Performance: AC voltage 4kv for 1 minute, 1.2 / 50us waveform pulse voltage 6kv <br>Product Description: <br>DDS1891 single-phase electronic DIN track active energy meter is a new type of single-phase two-wire active energy meter, which uses microelectronics technology, and introduces large-scale integrated circuits, and uses advanced digital technology and SMT technology. Its completely independent intellectual property rights and minimum size. <br>The meter full complies with the relevant technical requirements of the class 1 single-phase active meter specified by the international standard IEC62053-21. It can accurately and directly measure the 50Hz active power consumption from the single-phase AC grid, and can display the total power consumption through the stepper motor type pulse register. <br>It has the characteristics of good reliability, small size, light weight, beautiful appearance and convenient installation. <br>Features: <br>1.35mm standard DIN rail installation, in line with standard DIN EN50022. <br>2. Unipolar width (module 17.5mm), in line with standard DIN43880. <br>3. Display the standard configuration 5 + 1 number (99999.1kWh) through the stepper motor type pulse register. <br>4. Standard configuration of passive pulse output (polarity), long-distance pulse output passive (polarity) can be selected. And easily contact with various AMR systems, in line with standards IEC 62053-31 and DIN 43864. <br>5. When the meter starts measuring, the pulse indicator flashes. <br>6. One-way measurement of single-phase two-wire active power, independent of the direction of the load current trend. Comply with standard IEC 62053-21. <br>7. Standard configuration S type connection, U type connection can be selected. <br>8. Extend the terminal cover to protect the safety of use.<br>1、With excellent long?term reliability, small size, light weight and easy installation, etc. <br>2、Can directly and accurately measure the active power consumption of the load in a single?phase AC network with a rated frequency of 50 Hz <br>3、Adopt microelectronics technology, and large?scale integrated circuits, and adopt advanced digital technology and SMT technology. <br>4、Direct connection operation, you can choose two types of wiring, the standard configuration is S?type wiring, and it can be U?type wiring. <br>5、One&#8209;way measurement of single&#8209;phase two&#8209;wire active power has nothing to do with the direction of the load current trend.1 x Single Phase Meter<div>1 x User Manual&nbsp; &nbsp;</div>
