This type of three phase electric digital energy meter is the active energy metering meter with the data exchange method of numeric medium. The user can load the amount (quantity of electricity) which purchase in advance, make the statement by amout. This meter is equipped with numeric keyboard interface used to active energy metering and prepayment control.
| Meter Category | Three-phase four-wire |
| Accuracy class | Active energy: 1 class Reactive energy: 2 class |
| Rated current | 10(100) A |
| Impulse constant | 500 imp/kWh |
| Reference voltage | 3*230/400 V |
| Buzzer: |
| The energy meter have the function of Sound Warning, the ringing time can be set. When following events of the meter appear, the buzzer will emit tones discontinuously: |
| 1) Battery with low power 2) Current reverse 3) Open keypad cover 4) Open the upper cover 5) Open the terminal cover 6) Magnetic tamper 7) Hardware error 8) Reversal phase sequence 9) Phase loss 10) Over voltage 11) Three phase imbalance 12) Over current 13) The credit less than credit threshold |
| Load control and protection function: Energy meter can program and set user's electrical load threshold. And when energy meter detected that the current total power more than or the same as user's electrical load threshold, last to test time (default time is 1 minute), energy meter will disconnect user load. When the load threshold is zero, this function has no effect. |
