Choose PS3FX-R-D-N-D when you need direct DENTCloud connectivity with Modbus RTU/TCP. Choose PS3FX-R-D-N instead when the project requires BACnet MS/TP or BACnet/IP.

PS3FX-R-D-N-D — PowerScout FLEX 3 Multi-Circuit Power Submeter

The Dent Instruments PS3FX-R-D-N-D is part of the PowerScout™ FLEX 3 family, DENT's next-generation three-channel multi-circuit submeter that replaces the PowerScout™ HD. The PS3FX-R-D-N-D measures voltage, current, power, energy, and a wide range of electrical parameters on any combination of single- and three-phase loads, making it well suited to tenant submetering, bi-directional (import/export) metering, and real-time energy monitoring across commercial and industrial facilities.

The PS3FX-R-D-N-D delivers revenue-grade performance with continuous 7.2 kHz sampling (no blind cycles), a 1-second parameter update rate, and ANSI C12.1-2024 Class 0.2 accuracy when paired with an appropriate CT. It communicates over Modbus and streams data to DENTCloud simultaneously (BACnet is not available on DENTCloud-enabled models), and every FLEX 3 model — including this PS3FX-R-D-N-D — provides RS-485 serial and 10/100 Ethernet as standard. Setup is handled through FLEXPoint™ PC software or the browser-based FLEXPoint™ GO web server, and DENT's patented PhaseChek™ circuitry confirms correct CT orientation during commissioning.

This model ships as a DENTCloud™-enabled unit: the PS3FX-R-D-N-D is factory-provisioned for direct connectivity to the subscription-free DENTCloud™ platform, giving authorized users remote access to real-time and historical metering data through any web browser without adding a separate gateway.

Housed in a compact DIN rail enclosure that drops into the external enclosure of your choice (UL 94-V0 ABS), the PS3FX-R-D-N-D is delivered in the DIN Rail Mount Enclosure form factor. Like all PowerScout meters, the PS3FX-R-D-N-D is designed to operate as an endpoint that reports to a building management system, RTU, data acquisition device, or DENTCloud™ host rather than as a standalone recorder.

Best for

  • Tenant and accountability submetering in commercial, retail, and mixed-use buildings
  • Bi-directional metering for solar, wind, and other renewable or storage interconnections
  • Monitoring building mains, HVAC, pumps, motors, and equipment loads
  • Multi-circuit measurement using Virtual Meters to group the PS3FX-R-D-N-D's three channels by load
  • Hospitals, data centers, and government projects requiring BAA / TAA compliant equipment

Key Features

DENTCloud™ Enabled

The PS3FX-R-D-N-D is factory-enabled for direct connectivity to the subscription-free DENTCloud™ platform, giving authorized users remote access to real-time and historical metering data from any web browser without a separate gateway.

FLEXPoint™ + FLEXPoint™ GO

Configure the PS3FX-R-D-N-D from a rebuilt PC application or directly from any web browser with FLEXPoint GO — no software install required for on-site changes, validation, and field troubleshooting.

Flexible Virtual Meters

Assign any of the three CT channels to any load in any combination — single-phase, split-phase, or three-phase groupings — and meter multiple loads from a single PS3FX-R-D-N-D with consistent load labels across software, register exports, and cloud systems.

Modbus + DENTCloud, Serial + Ethernet

This meter communicates over Modbus (Modbus RTU or Modbus TCP) via RS-485 serial or 10/100 Ethernet while streaming data to DENTCloud simultaneously, with an IEEE-754 floating-point register map that eliminates scaling factors and flattens Virtual Meters to a single address. BACnet is not available on DENTCloud-enabled meters.

PhaseChek™ + Revenue-Grade Accuracy

Built-in PhaseChek verification confirms correct CT orientation and phase matching to reduce installation errors, while the PS3FX-R-D-N-D meets ANSI C12.1-2024 Class 0.2 revenue-grade accuracy (dependent on CT selection).

Universal CT Compatibility

Mix and match a full range of 333.3 mV CTs — Solid Core, Split Core, or RōCoil™ (Rogowski) — including revenue-grade options, measuring up to 4000+ A depending on the CT used with the PS3FX-R-D-N-D.
