NEW PRODUCT ANNOUCEMENT:
THE
POWERSCOUT 3 PLUS
POWERMETER - SUBMETER
DENT
Instruments is pleased to announce the introduction of the
PowerScout 3 Plus submeter. The
PowerScout™ 3 Plus is a single-point 3-phase monitors the voltage,
current, power, energy and many other electrical parameters and now is capable
of communicating via Modbus or BACnet data protocols. The PowerScout 3 submeter
was originally introduced in 2008 along with the PowerScout 18, and has been
sold successfully for permanent metering as part of a 3rd party Building
Automation & Control Systems or Energy Management Systems.
What is BACnet?
A major
application area for these meters is bundling with HVAC Controls. In this
market, BACnet is more commonly used as the data communications protocol.
BACnet is a standard developed under the auspices of the American Society of
Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) for building
automation and control systems.

The communications interface to the unit is an RS-485 serial connection that
uses the BACnet Master Slave Token Passing (MS/TP) protocol or Modbus protocol
for sending commands and retrieving data. A separate BACnet client (Data
Logger, or Building Management and Control System) is usually connected to the
PowerScout for BACnet. A separate remote terminal unit (RTU), Data Logger, or
Building Management and Control System is usually connected to the PowerScout
for Modbus mode. This separate unit provides data recording and trend logging
plus a human interface or display. BACnet or Modbus communications protocol is
selected using the rotary switches on the PowerScout 3 Plus.
Up to 127
PowerScout 3 Plus meters may be connected to
a single BACnet client for monitoring and recording power usage at multiple
locations within a single site. Up to 254 meters may be connected to
Modbus.
Digital I/O Ports Now Pulse
Output Only
The
PowerScout 3 Plus can also be used to
generate pulses for external devices such as data loggers that can accept
pulses but do not have BACnet or Modbus capability. The PowerScout 3 Plus can
generate pulses based on accumulated value(s) such as system kWh, system kVARh,
and system kVAh.
The pulse output is scaled by the same data scalar
register (44602) as are the Modbus registers. For example, when the data scalar
is set to 3, each pulse will represent .1 kWh, .1kVAh and .1kVARh.
