GENERAL DESCRIPTION
BM100 multifunctional power meter adopts the latest 32-bit ARM microprocessor and DSP, integrated with the full three-phase energy metering/display, energy accumulation, digital input and network communications. Large-size high resolutions LCD can meet with your demand completely and its elegant and bright backlit display can make you watch data clearly even at dark, HMI can let user operate it very easily. BM100 meter display the content in multiple rows, show several parameters at one time without pushing key.
SCADA
BM100 multifunctional power meter can work independently, to replace a lot of traditional analog meters. Also it can be used as the ending unit of SCADA, to perform the remote acquisition of data and control. Provided with RS-485 and MODBUS communication protocol, make it to form a network very easily, which is an ideal choice for SCADA system.
Energy Management
BM100 multifunctional power meter can measure and accumulate the bidirectional four-quadrant KWH and KWHr, and provide high level electricity data, which is a key factor for feeder statistics.
Remote Power Supervision
Though BM100 multifunctional power meter is mainly used to measure the data, also it provides full I/O functions, able to work as separate RTU, to perform remote signaling and remote measurement.
The follows are the main functions of this meter.
