Functions and Features:
1. Measuring electricity parameters, such as: bi-directional active/reactive energy consumption, current, three phase voltage, power, and power factor.
2. Data display and storage: current, last 10 days, last 2 months, and total group.
3. Load curve: Keep the data of last 96 data points (default interval of 15 minutes, settable via main station), mainly containing totalgroup data (active/reactive power/energy curve) and point data (three phase total active/reactive power curve, active/reactive energy value-indicated curve, phase energy value-indicated curve, total and three phase power factor curve, three phase voltage/current curve).
4. Voltage passing rate statistics: according to the upper and lower limit voltage for equipment daily voltage statistics, max and vain voltage with occurrence time can be recorded (memory size: 10 items).
5. Channel: GPRS, CDMA.
6. Data transmission:
   Active: report relevant data and abnormal alarm information at regular time.
   Passive: take orders of detection (real-time data or historical data) and set up, etc.
7. Equipment self-inspection, reporting running state and fault information.
8. Parameters can be settable via local port, infrared and 485 ports.
9. Adapt itself to hi-low temperature, high humidity and other harsh operating environment.
10. Remote control functions.

Specifications and Parameters:
1. Voltage measuring scope: (50% Un ~ 120% Un), not less than accuracy class 1 <Error:±(1% Rd +1)V>
2. Current measuring scope: 0.1A ~ 6A, not less than accuracy class 1 <Error:± (2% Rd +0.01) A>
3. Supply mode: Three phase power supply. The terminal still works normally even if power cut happens to one phase (3 phase 3 wire) or two phase (3 phase 4 phase)
4. Standard voltage:±20% X rated voltage (3X100V, 3X57/100V, 3X220W380V)
5. Power consumption: 1VA/Phase in the waiting state (no communication with the front end processor)
6. Standby power supply: communicate with the main station at least one time (report the date, time, active/reactive power), keep data and maintain the clock chip (battery life: >=5 years) under the conditions of AC power failure
7. Local interface: Set up and read data via infrared or RS485
8. Outside size: 277Lx 171Wx 77H mm.
