POWERCOM
The M550
PowerCom is a complete 1 phase or 3 phase multifunction AC power transducer
packaged in a standard 100mm DIN enclosure.
The M550 is fully programmable
through the communication port.

ACCURACY
The accuracy of the M550 is Class 0.2 to IEC 688 over the range
10% to 120%. For Active and Reactive energy the accuracy is 1% of reading to
IEC 1036.
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.
