Dent Instruments PowerScout 3 Plus Networked Modbus Power Meter
The PowerScout 3 Plus networked power meter is a submeter designed to provide timely and accurate consumption data
necessary to gain the upper hand on electrical costs in today’s
escalating energy market. These meters can capture kWh/kW energy and
demand data as well as virtually all relevant energy parameters for
diagnostics and monitoring on three-phase or single-phase circuit
installations. The PowerScout’s flexibility, size, and ease-of-use make
them ideal tools for gathering detailed consumption information in
commercial, industrial, government and retail environments.
The new PowerScout 3 Plus includes BACNET protocol compatibility and was released December 2011 replacing the first generation PowerScout 3.
The PowerScout 3 Plus uses direct connections to each phase of the voltage and various pre-wired CT options such as split-core current transformers or flexible Rogowski coils (for large loads or large cables and busbars) to monitor current on each phase. All split-core CTs are internally shunted with ETL and CE mark for intrinsically safe operation on energized conductors. Special high-accuracy CTs are available for existing CT secondary monitoring. Also use on high voltage applications with PTs
The PowerScout 3 makes over 50 total electrical measurements which are derived from the voltage and current inputs. Electrical load diagnostic parameters such as power factor (both Apparent and Displacement) and line frequency are captured in addition to energy and demand values. A 4-wire 3-phase version is available for monitoring and Neutral phase on potentially unbalanced loads.
Communications interface to the PowerScout is through an RS-485 serial connection using the industry standard Modbus protocol. Up to 254 PowerScout meters may be connected to a single RTU or datalogger for monitoring and recording power usage at multiple locations within a single site.
The PowerScout 3 requires no external power and its power supply can accommodate service voltages ranging from 60-600V (phase to phase). The simple installation is accomplished by connecting the color-coded voltage leads and clearly labeled CTs. DENT’s patent pending PhaseChek™ circuitry includes a 3 LED indicator display that confirms proper CT to phase installation. The PowerScout automatically adjusts for CT orientation—greatly reducing set-up time and all but eliminating installation errors.
NOTE: PowerScout Meters require the purchase of factory-matched CTs. A wide range of CTs is available under the accessories tab or by adding this product to your shopping cart.
