PS48FX-P-D-N — PowerScout FLEX 48 Multi-Circuit Power Submeter
The Dent Instruments PS48FX-P-D-N is part of the PowerScout FLEX 48 family, DENT's next-generation 48-channel multi-circuit submeter that replaces the PowerScout™ HD. The PS48FX-P-D-N measures voltage, current, power, energy, and many other electrical parameters on any combination of single- and three-phase loads — up to 16 three-phase or 48 single-phase circuits across two voltage references — making it well suited to high-density tenant submetering, bi-directional metering, and real-time monitoring across commercial and industrial facilities.
The PS48FX-P-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, includes four digital pulse inputs and a 12 VDC auxiliary output, and provides RS-485 serial and Ethernet as standard. Setup is handled through FLEXPoint™ PC software or the browser-based FLEXPoint™ GO web server, and DENT's patented PhaseChek™ circuitry (U.S. Patent 7,612,552) confirms correct CT orientation during commissioning.
Built as a UL-Recognized circuit board on a mounting plate, the PS48FX-P-D-N is delivered in the Mounting Plate configuration. Like all PowerScout meters, the PS48FX-P-D-N operates as an endpoint that reports to a building management system, RTU, or data acquisition device rather than as a standalone recorder.
Best for
- High-density tenant and accountability submetering — up to 48 circuits from one device
- 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 PS48FX-P-D-N's 48 channels by load
- Hospitals, data centers, and government projects requiring BAA / TAA compliant equipment
Key Features
FLEXPoint™ + FLEXPoint™ GO
Configure the PS48FX-P-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 48 CT channels to any load in any combination — single-phase, split-phase, or three-phase groupings — and meter multiple loads from a single PS48FX-P-D-N with consistent load labels across software, the LCD, register exports, and cloud systems.
Dual-Protocol + 4 Pulse Inputs
The PS48FX-P-D-N speaks both BACnet and Modbus over RS-485 and Ethernet, adds four digital pulse inputs for gas, water, or other meters, and uses an IEEE-754 floating-point register map that flattens all 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 PS48FX-P-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 PS48FX-P-D-N.
BAA & TAA Compliant
DENT Instruments marks the PowerScout FLEX 48 Buy American Act (BAA) and TAA compliant, supporting procurement requirements common to government, healthcare, and institutional projects.
