Drei-Phasen-Multifunktions-Elektro-Energie-Messinstrument

Three-phase Multifunction Electricity Power Meter,Electric Energy Meter,kWh Meter,Watt-hour Meter KN3410B-B2000-DC(LT) Three-phase multifunction meter meets the IEC 62053-21 * (Class 1) standard for multifunction energy meters. The main features include none physical adjustment components, digital signal processing, digital filters, digital error correction, digital calibration, immunity to temperature fluctuation, and excellent stability. Due to its 12 times overload multiplier, Meter can record energy usage of extreme low load. The basic functions include active, reactive & apparent bidirectional (import and export) and up to 4 tariff energy metering and maximum demand indications. Data communication protocol meets IEC 62056-21 / IEC 1107(C mode). User can configure meters parameters and read meters data using PC.

Error at 23±2: ±0.5 seconds/day 4.Delay of Time Block Switch Less than 0.1 second 5.Back-up Battery One long-lifetime super lithium battery is provided to be used for power-down protection for clock, data and time block settings. Lifetime of the super lithium battery: ≥20 years. 6.Data Output Interface Optical communication port baud rate can be set to 300, 1200, RS485 port can be set to 300,1200,2400,4800,9600. Protocol meets IEC 62056-21. Through this port, user can configure parameters and read energy data. 7.Terminal The meter terminal cover is of the long type with cable entry knock-offs. For directed connected type meters, B2000-DC has 10mm diameter hole for cables. B2000-DC has a sealed cover on the IP links so that to reach these links a seal has to be broken to avoid fraud and electricity theft. When the meter is issued for installation after testing and sealing in the customer lab, the installation technician in the fielddoes NOT have access to these links without breaking this seal.
