AVAILABLE MODELS
EMC-D3b: 3-phase energy counter with 7+1 digit display. 1 digital
input and two digital pulse output for kWhr and kVArhr.
EMC-D3b-485: 3-phase energy counter with 7+1 digit display, 1
digital input, two digital pulse output for kWhr and kVArhr, EIA-
RS485 serial communication port, Modbus RTU protocol.
Both are manufactured in DIN rail mounting case 6 modules 17.5
mm.
INTRODUCTION
The EMC-D3b models allows the local or remote counting of the
energy, with the help of a serial interface.
It is possible to set the instrument to count in 3 differents mode
(Normal / Total and partial / Timeband).
Also the instrument is equipped with a digital input which can cover differents function. See the
more information.
The auxiliary power supply is taken from same Voltage inputs (VL1 and VL2), used for measuring.
It's available as option the instrument for single phase networks.
OPTIONS and ACCESSORIES
options: - internal CT's ( not for direct line insertion) (order with -t suffix)
- current inputs for ... /1A current transformer (order with /1A suffix)
- current sensor for low current measures (Max 15 Amp) (specify when ordering)
- power supply and measuring voltages other than the standard (specify when ordering)
- power supply separated from measuring voltage (specify when ordering)
- single phase network ( power supply is taken from VL1 and neutral) (specify when ordering)
