INTRODUCTION
PowerScout™ Meters
PowerScout meters monitor the voltage, current, power, energy, and many other electrical parameters
on single and three-phase electrical systems. A PowerScout meter uses direct connections to each phase
of the voltage, and uses current transformers to monitor each phase of the current. Information on
energy use, demand, power factor, line frequency, and more are derived from the voltage and current
inputs.
The communications interface to the meters is an RS-485 serial or Ethernet connection (PS3 Plus
Ethernet only) that uses the BACnet Master Slave Token Passing (MS/TP) protocol or Modbus protocol
for sending commands and retrieving data. A separate remote terminal unit (RTU), Data Logger, or
Building Management and Control System is usually connected to the PowerScout to provide data
recording and trend logging plus a human interface or display.

The PowerScout 3 Plus is light-weight and compact enough to mount within an electrical
panel. It is typically used for quick in-and-out monitoring of electrical systems.
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 247
meters may be connected to Modbus.
There are two configurable digital pulse output ports on the PS3. The ports can be used to
output kWh, kVARh, or kVAh pulses to external devices, or to toggle on and off to control a
remote device or relay.

24
The PowerScout 24 is capable of reading eight elements at a time and is
mounted near the breakers. It is typically used for long-term monitoring of
electrical systems.
Up to 127 PowerScout 24 meters may be connected to a single BACnet client
for monitoring and recording power usage at multiple locations within a
single site. Up to 30 meters may be connected to Modbus. There are eight
configurable digital pulse output ports on the PS24. The ports can be used to output kWh, kVARh, or
kVAh pulses to external devices, or to toggle on and off to control a remote device or relay. There are
also two digital pulse input ports. Pulse input is used to count, accumulate and scale pulses received
from non-DENT external pulse-initiating meters such as gas, water, or other electrical meters. The
PowerScout 24 can be purchased either in an enclosure (PS24-D) that is UL-listed or as a standalone PC
board (PS24-N) that is UL recognized and must be installed in a user-supplied enclosure.
