Item Type: 3-Phase meter Model: DTS1891 Product Material: Pure copper + plastic Voltage: 3 x 230V/400V Current: 3 x 5 (100) A Power: 400imp/kwh 50Hz Insulation Performance: AC voltage 4kv for 1 minute, 1.2 / 50us waveform pulse voltage 6kv Functions and Features: 1. 35mm standard DIN rail installation, in line with standard DIN EN50022. 2. Ten widths (modulus 12.5mm), in line with standard DIN43880. 3. Standard configuration 6 + 1 (999999.1kWh) LCD display. 4. Standard configuration of passive pulse output (polarity), long-distance passive pulse output (no polarity) can be selected. It also complies with IEC 62053-31 and DIN 43864 standards, making it easy to contact with various AMR systems. 5. Two LEDs indicate power status (green) and energy pulse signal (red). 6. Direction measurement of AC active power consumption. The direction in which the load current flows does not matter. Meet the standard IEC62053-21. 7. Direct connection operation, two types of wiring can be selected. The standard configuration is S-type wiring, but U-type wiring is possible. 8. Extend the terminal cover to protect the safety of use.
