Energy Meter:

Main features

1 Measurement Function

1.1 Measure forward and reverse active energy

1.2 Measure forward and reverse reactive energy 1.3 Measure maximum demand and real time of forward and reverse active and reactive energy

1.4 Measure 4 -quadrant reactive energy1.5 Measure forward active energy  of split phase of  A, B, C phase 2  Multi-tariff function2.1 Be programmable for 4 tariffs, 20 time periods, 13 daytime periods table, 4 time zones and 30 public holidays;2.2 Built-in clock with calendar and time functions3  Display function3.1  LCD display, shows clearly In -20 ~ +50 temperature range3.2  Parameters displayed by turn with parameters, time and order settable function3.3  Set parameters of key pressing3.4  Display power cut4  Communication Function

4.1 The energy meter has two RS485 interface and an infrared communication interface

4.2  Electrical isolated from RS485 interface and inner of the meter with design of avoiding lightning struck4.3 Communications refer to the DL/T 645-1997

5  Output function5.1  Active and reactive pulse testing port output

Forward and reverse active and reactive remote pulse output 5.2With 1 Hz clock output5.3With testing port of demand circle6  Real-time measurement and event record function6.1  Real-time metering of voltage, current and virtual value, and active power, reactive power, power factor and the current frequency of A, B, C three phase

6.2  With event record function of voltage failure, current failure, lose of phase, power cut, programming, energy resetting, meter electrifying etc.6.3  With load curve record function.
