DENT Instruments has responded to the growing needs of the energy and building automation control markets by introducing the PowerScout HD (PSHD) series of networked power meters. The HD moniker reflects a “High Definition” design by bringing more points into a single meter and increasing data fidelity. While the original PowerScout series and the new PSHD series share many of the same popular features such as: being self-powered from line voltage, multi-protocol in all models, and ease of configuration, there are some important distinctions of which integrators and end-users need to be aware.
This guide defines key differences between the PowerScout 3037 and the new PowerScout 3 HD power meters. If you have used PowerScout 3037 before, and are either replacing a PowerScout 3037 with a PowerScout 3 HD, or working in an environment with both meter types, please read on. For questions outside the scope of this guide, please refer to the PowerScout HD Manual or contact us.
Main Differences: PowerScout 3037 vs. PowerScout HD
- The Modbus register and BACnet Objects schemes are different between the PS 3037 and PS 3 HD meters. The PS3 HD meters report all data in a floating-point format which requires less manipulation (such as scaling) by the host RTU. Register organization has been improved by adopting the SunSpec three-phase net metering model as a basis. The PS3HD register/object list is shared by all PowerScout HD meter models and is available as an Excel® document. The PowerScout 3037 and PSHD register space is non-overlapping so that both meter types can exist within the same network allowing for expansion with minimal disruption of existing scripts and programs. BACnet object types in PSHD have been updated to include all the Standard Objects in BACnet version 135-2016 including organization of elements through Structured View.
- The Windows® configuration utility “ViewPoint HD” is not compatible with PowerScout 3037 and can only be used with PSHD meters. PowerScout 3037 devices must continue to use legacy ViewPoint 4 software. PSHD meters can utilize updated ViewPoint HD software, which includes new analysis and troubleshooting features such as waveform capture, phasor plotting, and harmonic analysis. The PSHD meter can also be configured via a smartphone or tablet via the meter’s built-in web server.
- New capabilities: The PowerScout HD Series has expanded upon the feature set of the PowerScout series by adding Alarms, Interval Data Recording, and Pulse Inputs. Along with new features comes new analytics such as THD, Theta, and installation diagnostics.
We have highlighted major differences between the product lines in a series of tables on the following pages. Please review this document, along with the PowerScout HD Manual, prior to working with or installing the meter.
