EM733 3 Phase 4 Wire Kwh Meter Din Rail Mounted Energy Meter With s0 Output

     EM733 3 phase 4 wire kwh meter  din rail mounted energy meter with s0 output

                                                     current: 10(100)A

Main Functions and features:

   three phase enery meter 

   Standard DIN rail Format (DIN43880)

   CI.1 Accuracy (EN50470)

   Energy consumption LED

   Pulse output for remote energy management 

   Direct metering up to 100A

   7 DIN modules

Measuring function:

On the EM733’S front panel, there are five LED, respectively, for the Active energy pulse light, current reverse ,Phase L1/L2/L3 . The constant of the impulse is shown on the nameplate of the meter.
The energy meter is equipped with 6 digits electromechanical counter, which is used as recording consumption and can’t be reset to zero.
The  reverse LED will flicker when Current wiring is reversed in order to remind users to revise the wiring. The meter will work normally under this condition

Pulse output:

    EM7333 din rail energy meter is equipped with a pulse output which is fully separated from the inside circuit.
  The test pulse output is a polarity dependant, passive transistor output requiring an external voltage source for correct operation. For this external voltage source, the voltage (Ui) should be 5-27V DC, and the maximum input current (Imax) should be 27mA DC. To connect the impulse output, connect 5-27V DC to connector 23 (anode), and the signal wire (S) to connector 24 (cathode). The meter pulses is indicated on the front panel.
