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.
Set-up and monitoring software is available
free from your Multitek distributor or visit the Multitek website
