PANELTRACK
The PanelTrack energy management instrument is a panel mount energy recorder designed to provide detailed information of a specific electrical feed. Extensive communications capabilities (local & remote) enable fast and accurate information retrieval and the software provides a graphical interface for quick and easy analysis of recorded data.
Product summary
PRODUCT SUMMARY
The digital display and RS485 communications port of the PanelTrack enables it to be used in a stand-alone mode or as a remote kWh/kVA meter in a distributed sub-metering or energy management system. The unit has the following main functions:
- Complete kWh and kVA demand metering (Thermal & Block) with 12 month history.
- Extensive load profiling, recording per phase and summated parameters.
- Panel meter, displaying instantaneous values on the graphical screen.
- Setpoint Control with 4 relays for switching loads.
ENERGY MEASUREMENT
The PanelTrack is suitable for any three-phase metering applications.
Energy consumption is accumulated into an internal grand total non-resetable counter and the kVA demand is registered and saved in month-end blocks.
There are up to 13 energy blocks (current + 12 history) stored in memory and the demand can be calculated over 15, 30 or 60 minute intervals. These demand blocks can then be reset using the keypad, via remote communications or via the onboard clock.

General information
GENERAL INFORMATION
VOLTAGE AND CURRENT INPUTS
The PanelTrack is connected in the standard four-wire or three-wire configuration. The voltage inputs of the instrument can be factory set for input voltages of either 380V or 110V AC. The current inputs interface to the supply system through external 5A current, but can also be manufactured to accommodate flexible coils allowing for easy installation.
RS485 COMMUNICATIONS PORT
The PanelTrack features a RS232 and RS485 serial communications port using the ModBus RTU protocol. The RS232 port can be used for local communications to a portable computer for on site configuration. It also serves as a communications interface for remote metering applications. The RS485 port is utilised in distributed systems where each PanelTrack is ModBus addressable in the range 1-255.
RATE INDICATOR
The PanelTrack employs a 2 rate indicators in the form of flashing light emitting diodes. These indicators flash once for every 1Wh and 1Varh (multiplication factor of unity) of energy consumed. The rate indicators are also used for on-site verification of meter accuracy.
LOAD PROFILE RECORDING
The PanelTrack records all power parameters, per phase as well as summed, at selectable intervals of 1, 2, 5, 10, 15, 30 or 60 minutes/seconds. These recorded values can be viewed analyzed via the PanelTrack or PowerServe Software.
SETPOINT CONTROL
The PanelTrack comes equiped with 4 relay outputs and 4 digital inputs which can be utilized for setpoint control. The setpoint control switches the relays when a pre-programmed condition occurs. The condition connected to a specific relay can be selected from a list of power parameters (kVA, kW etc.) where a threshold value is pre-programmed or the 4 digital inputs and power parameters can be used in conjunction with various boolean equations (and gates, or gates, invertors, delay timers and periodic timers).
