MEMORY
All data including energy registers, current
and voltage ratios and calibration data is
stored in a non volatile eeprom.

COMMUNICATIONS
PowerCom uses RS485 Modbus protocol.
This enables remote reading and programming of
the PowerCom via a host computer.
The RS485 allows up to 32 PowerComs to be
connected in parallel, allowing them to be used
with PC, PLC, RTU, Data loggers and Scada
programs.
The PowerCom’s communication port is
auto-configurable meaning that when connected
to an existing Modbus network it will
automatically set Baud rate, Parity and Stop bits.
A red LED is provided to indicate power is
present, and the unit is communicating correctly.

PULSED OUTPUT
An option of pulsed output via a relay is offered.
The pulsed output can be assigned to W.h, VAr.h,
(import or export), A.h or VA.h.

PROGRAMMING
CT and VT ratios, demand time, assigning relay
to different parameters, pulse duration etc. can all
be programmed via the RS485 port.
Set-up and monitoring software is available free
from your Multitek distributor or visit the
Multitek website www.multitek-ltd.com
