The EPM 5350P offers the following features other than
in the series
• Ethernet TCP/IP
The 5000P/5200P/5300P/5350P device series offers the
following features:
• Measures Volts, Amps, Watts, Vars, VA, PF,
Frequency, Watt-Hour, VA/hour, VAR/hour
• Measure Harmonics to the 31st Order
• Provides Captured Waveform of Voltage and
Current Set Point
• Control With Logical Descriptors Relay Outputs
and Pulse Outputs Max and Min for
• Ten Channels of Analog Outputs
(0-1 or 4-20mA)
• KYZ-Pulse Outputs (For EPM 5200P)
MicroVersaTrip-C and -D and
Spectra MicroVersaTrip Trip Units
PMCS supports three varieties of this popular line of
electronic trip units: the Enhanced MicroVersaTrip-C,
Enhanced MicroVersaTrip-D, and the Spectra
MicroVersaTrip. MicroVersaTrip trip units act to trip
the circuit breaker when one of the following user-
defined parameters is exceeded (parameters identified
by an asterisk are optional features of the trip unit.):
Overcurrent
• Long-time
• Short-time*
• Instantaneous
• High-range instantaneous*
• Ground fault*
• Zone select*
Protective relays*
• Overvoltage
• Undervoltage
• Overcurrent
• Voltage unbalance
• Current unbalance
• Reverse power
The MicroVersaTrip trip unit is also capable of limited
metering functions. It can measure current and voltage
at a circuit breaker and use these to calculate other
electrical parameters. Information on current is
supplied by the breaker’s current sensors. Voltage
information is supplied by the equipment bus potential
transformers through voltage conditioners.
It can measure or calculate values of the following
parameters.
• RMS current: phases A, B, and C
• RMS voltage: phases A, B, and C
• Watts: phases A, B, and C
• Volt-amperes: phases A, B, and C
• Watt-hours: phases A, B, and C
• Frequency
• Power factor
Modbus Concentrator
The POWER LEADER Modbus Concentrator allows
PMCS to communicate with POWER LEADER
commnet IEDs. The Modbus Concentrator is an RS-
485-native IED that collects data from up to 32 attached
POWER LEADER commnet IEDs and communicates
this data to the PMCS across the POWER LEADER
Modbus communication network. In this respect, the
POWER LEADER Modbus Concentrator effectively
serves as the host IED on up to eight commnet networks
while acting as a slave to the master-slave Modbus
network.
The major functions provided by the POWER LEADER
Modbus Concentrator are:
• Configuration of commnet IEDs
• Data collection from commnet IEDs
• Processing of metering data
• Demand and Energy calculations
• Processing of events (trips and alarms)
• Executions of commands upon host request
Electronic Power Meter (PLEPM)
The POWER LEADER Electronic Power Meter
(PLEPM) is a full-function electronic meter with
optional pulse initiation. The PLEPM continuously
monitors specified line characteristics and shows the
desired functions and calculated values on a two-line,
back-lit liquid crystal display on the front panel.
The PLEPM monitors and stores values for each
current and voltage input. From these values it
calculates RMS voltage, RMS current, real and reactive
power, and other time-based functions. Data are then
sent automatically to the display.
The PLEPM monitors and displays the following
electrical parameters:
• RMS current (Phases A, B, C and neutral)
