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 supports both BACnet and Modbus, 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 Made in USA / BAA / TAA 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.
Dual-Protocol, Serial + Ethernet
The PS3FX-R-D-N-D speaks both BACnet and Modbus and includes RS-485 serial and 10/100 Ethernet on every model, with an IEEE-754 floating-point register map that eliminates scaling factors and flattens Virtual Meters to a single address.
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.
