The New PowerScout 3 HD from Dent Instruments is the latest model in the HD family replacing the PowerScout 3037 as DENT Instruments’ 3-channel 3-phase meter. DENT's single-point meter boats features like increased measurement performance, industry-standard communications, and two form factors. It can utilize any of DENT’s internally-shunted, 333 mV output split-core or RōCoil CTs. Users can monitor a single three phase load or network with other PowerScout HD meters to monitor several loads across facilities.
The high speed continuous sampling enables data updates at a rate of 1 Hz and ANSI C12.20-2015 Class 0.2 revenue grade accuracy (depending on CT), the PowerScout 3 HD is ideal for accountability metering in commercial, retail, and industrial facilities including demand response and tenant submetering.
The PS3HD are line-powered with an internal wide-range power supply, allowing line-to-line voltages from 90-600 VAC. For convenience, the PS3HD also includes a USB (Type C) connector which allows the meter to be powered from a host PC or laptop computer during configuration.
The PowerScout 3 HD supports both Modbus (based on SunSpec IEEE-754) and BACnet communications protocols. Communications interface can be accomplished through serial RS-485 or Ethernet using either Modbus RTU, BACnet MS/TP, Modbus TCP, or BACnet IP protocols.
The PowerScout 3 HD can be quickly configured using one of two interfaces: ViewPoint HD PC Application or through a Web Browser. Configurations can be saved to a template for re-use. Use the on-board LCD and thumb wheel to verify setup.
The PowerScout 3 HD meter features DENT’s patented* PhaseChek™ circuitry for detecting mis-phased and backwards CTs. When used in conjunction with ViewPoint HD, advanced analytics are available including waveform visualization, vector polar plotting and harmonic distortion analysis.
The PS3HD is equipped with several safety features to ensure the protection of all users. Some of the features include:
- • When the high-voltage (TouchSāf™) cover* is installed on the PowerScout HD meter, the NFPA70E-compliant USB interface is safe to use without the use of additional PPE or shutting off the electrical panel.
- • The 200 KAIC fuse that is standard on all PowerScout HD meters exceeds most regulatory requirements to make it the safest meter on the market.
- • The PowerScout HD meters have been evaluated to withstand 6kV line surges.
Always follow all local electrical codes and employer guidance regarding the use of PPE and other safety requirements.
* High-voltage (TouchSāf™) cover is standard on all PowerScout HD instruments except plate versions of the PowerScout 12 HD (PS12HD-P-D-N & PS12HD-P-N-N). Contact the factory for details.
The PowerScout Series meters are not meant to be standalone energy recorders. They are designed to connect as a slave device to a data logger, Remote Terminal Unit (RTU), or building management host network.
