THREE PHASE FOUR WIRE MULTI-FUNCTION STATIC WATT-HOUR METER

MEASUREMENT FUNCTION:

  Can be recording the energy (kWh/kvarh) with time-scales in 11 months and current, time-measuring positive and negative active electric power and four-quadrant reactive electric energy, and store their data in the designated meter reading, go on date dump.

  If the electric energy meter power down cross the time of freezing, after power on carry out the electricity and the demand freeze, the time across to several freeze times, they are dump several freeze data(electricity/demand synchronization)

COMMUNICATION FUNCTION:

  By remote infrared, RS485 or GPRS wireless communications for meter reading meter program or data in support of the statute of ministry of electric power

  Remote infrared, RS485 communication and GPRS wireless communications independence at the physical layer, the damage of a communication channel to each other channel does not affect

  Remote infrared communication interface: communication rate 1200 bps~9600ps(can be choose)

  GPRS communication: CPU of wireless communication module is uses of the mainstream 32 bits RISC microprocessor and plus the embedded operating system design scheme to meet the data forwarding, terminal communication, data management , and other complex functional requirement.

Multi-rate function:

  14 tariff, 12 time zone sheet, 8 sets of time-period sheets, 13 public holidays

  Within watt-hour according to the user set rates for electricity accumulation, when the load period of the conversion, the rate automatically switches into a new load period rates. This feature can be easily satisfied for the user, such as the rates switch of the wet period, dry season as well as the seasonal.
