PS12HD-C-N-N — PowerScout 12 HD Multi-Circuit Power Submeter
The Dent Instruments PS12HD-C-N-N is the PowerScout™ 12 HD, DENT's networked 12-channel, three-phase submeter. The PS12HD-C-N-N measures voltage, current, power, energy, and many other electrical parameters on any combination of single- and three-phase loads — up to 4 three-phase or 12 single-phase circuits — and can network with other PowerScout HD meters to cover multiple loads across a facility.
Looking ahead? The PowerScout FLEX 12 is DENT's next-generation replacement for the PowerScout HD — faster commissioning with FLEXPoint™, browser-based FLEXPoint™ GO, flexible Virtual Meters, and 7.2 kHz sampling.
See the PowerScout FLEX 12 →The PS12HD-C-N-N delivers revenue-grade performance with 1.8 kHz sampling, a 1-second update rate, and ANSI C12.20-2010 Class 0.2 accuracy (depending on CT). It supports both Modbus (SunSpec IEEE-754) and BACnet over RS-485 or Ethernet, includes four digital pulse inputs, and provides a 12 VDC auxiliary output. DENT's patented PhaseChek™ circuitry (U.S. Patent 7,612,552) confirms correct CT orientation during commissioning.
The PS12HD-C-N-N is the no-display configuration, commissioned and read through ViewPoint HD or the network — a good fit for panel and enclosure builds where a local screen is not required.
Built as a UL-Listed ABS enclosure, the PS12HD-C-N-N is delivered in the Enclosure (Case), No Display configuration with a high-voltage cover and is configured through ViewPoint HD PC software or a web browser. It operates as an endpoint reporting to a building management system, RTU, or data acquisition device.
Best for

- Bi-directional metering and demand-response monitoring
- Real-time power monitoring of building mains and equipment loads
- Networked metering of several loads alongside other PowerScout HD meters
- Projects requiring BAA / TAA compliant equipment
Key Features
Revenue-Grade Accuracy + PhaseChek™
The PS12HD-C-N-N meets ANSI C12.20-2010 Class 0.2 revenue-grade accuracy (dependent on CT) with NIST-traceable calibration, and patented PhaseChek™ circuitry (U.S. Patent 7,612,552) flags mis-phased or backwards CTs during commissioning.
Dual-Protocol + 4 Pulse Inputs
The PS12HD-C-N-N communicates over Modbus (SunSpec IEEE-754) or BACnet using RS-485 or Ethernet (Modbus RTU, BACnet MS/TP, Modbus TCP, or BACnet IP) and adds four digital pulse inputs for gas, water, or other meters.
12 Channels, One Device
Meter up to 4 three-phase or 12 single-phase circuits across two voltage references from a single PS12HD-C-N-N, reducing hardware and panel space versus single-circuit meters.
ViewPoint HD Setup
Configure the PS12HD-C-N-N from ViewPoint HD or a web browser, scan the network to find and name every PowerScout HD meter, and pre-build configuration templates — even without the meter on hand — for fast, repeatable deployment.
Universal CT Compatibility
Use the PS12HD-C-N-N with DENT 333 mV Split Core or RōCoil™ (Rogowski) CTs, including revenue-grade options, measuring up to 4000 A depending on the CT selected.
BAA & TAA Compliant
DENT Instruments marks the PowerScout 12 HD Buy American Act (BAA) and TAA compliant, supporting government, healthcare, and institutional procurement requirements.
