PS3FX-C-D-N — PowerScout FLEX 3 Multi-Circuit Power Submeter
The Dent Instruments PS3FX-C-D-N is part of the PowerScout™ FLEX 3 family, DENT's next-generation three-channel multi-circuit submeter that replaces the PowerScout™ HD. The PS3FX-C-D-N 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-C-D-N 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-C-D-N — 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.
Housed in a self-contained wall-mounted ABS enclosure (UL 94-V0 ABS), the PS3FX-C-D-N is delivered in the Wall Mount Enclosure form factor. Like all PowerScout meters, the PS3FX-C-D-N is designed to operate as an endpoint that reports to a building management system, RTU, or data acquisition device 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-C-D-N's three channels by load
- Hospitals, data centers, and government projects requiring BAA / TAA compliant equipment
Key Features
FLEXPoint™ + FLEXPoint™ GO
Configure the PS3FX-C-D-N 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-C-D-N with consistent load labels across software, register exports, and cloud systems.
Dual-Protocol, Serial + Ethernet
The PS3FX-C-D-N 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-C-D-N 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-C-D-N.
BAA & TAA Compliant
DENT Instruments marks the PowerScout FLEX 3 Buy American Act (BAA) and TAA compliant, supporting procurement requirements common to government, healthcare, and institutional projects.
