The PowerScout’s flexibility, size, and ease-of-use make them ideal tools for gathering detailed consumption data in commercial, industrial, government and retail environments.
New models – PowerScout Series
PowerScout 3037 – Replaces the PS3 series
The PowerScout 3037 comes in four basic configurations depending on whether a display or Ethernet port are desired. Instead of having one specific meter for a single job, the PowerScout 3037 can adapt to nearly any project requirement.
All PowerScout 3037 models have a broadband power supply (80-600VAC) and can be paired with a variety of current transformers, from split cores that measure <1A up to large RoCoils designed for measuring 4000A. Please see below for the available current transformers.
In addition, communication protocols are field-selectable. Easily toggle between Modbus or BACnet using ViewPoint software.
STANDARD PULSE OUTPUT
Send kWh or other pulses to an external device. The pulse output is used to generate system kWh pulses for devices, such as data loggers, that can accept pulses, but do not have BACnet or Modbus capability.

DENT’s PowerScout series networked power meters are submetering devices 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 PowerScout uses direct connections to each phase of the voltage and various interchangeable CT options such as split-core current transformers or flexible RoCoils (for large loads or large cables and bussbars) to monitor current on each phase.
Every PowerScout has embedded Rogowski coil CT amplifier/integrator circuitry—no need to provide external power to the CTs.
- All DENT CTs are internally shunted and carry UL or ETL certification and CE Mark for intrinsically safe operation on energized conductors.
- Special highaccuracy CTs are available for existing CT secondary monitoring.
- The PowerScout makes over 50 total electrical measurements which are derived from the voltage and current inputs, including energy and demand values.

Powerscout™ Current Transformers
Each CT type offers its own particular advantages depending on your application.
DENT CTs are interchangeable to meet your varying project requirements.
Current Transformers for PowerScouts (pdf) Note that the PowerScout 3037 has a higher accuracy rating than the ElitePro XC, so the CT specifications are better in this data sheet. See below for more details on this.
The CT models and prices are the same as the ElitePro XC Current Transformers:
Prices do not include GST and may change without notice. (11/15)
Choosing Current Transformers
As a general rule of thumb, you should choose a CT where the average measured current is about 75% of the CT’s max range.
This not only provides best accuracy, but best resolution. Using a large CT to measure a small current provides poor resolution and accuracy.
The bottom end range, or turn down of CTs, can be a “can of worms”, and can change depending on what equipment the CTs are connected to. Contractors hook CTs up to all sorts of things.
The general spec. for the “small” split core CTs, is therefore:
5-65A for the 50A CT, & 10-130A for the 100A CT.
However the same CTs when used with a PowerScout 3037, which has high input sensitivity, can be:
1-65A for the 50A CT, & 2-130A for the 100A CT, as depicted & stated on the PowerScout 3037 brochure.
However, the separate spec sheet for all the CTs, has just used the general spec without adjusting ranges at the bottom end to account for the extra PS 3037 sensitivity.
If you require split core CTs with good turn down & bottom end sensitivity, look at the Mini & Midi hinged split core CTs with their ferrite cores. The Mini & Midi hinged split core CTs are cheaper than the iron cored SCS 50 & 100A CTs and have a better turn down. The only reason a client might choose an iron cored SCS-050 or SCS-100 CT, is if the larger cable opening was required.
As an example: “The RoCoil CTs when used with the ElitePro SP energy logger (top of this page) have been rated safely, as 50 – 5000A, although I have always been able to read them accurately to 20A, at which point the ElitePro SP would cut the readings off.
However, greater sensitivity with the latest ElitePro XC, has resulted in a cut off point for the RoCoils of just 5A.
ie: useful range of 5-5000A, which is a turn down ratio of 1000:1, which is remarkable.
However, there is no guarantee that a measurement of 5A can be made if the RoCoil is connected to some other piece of equipment.”

Dent TCA-5 Module: You can now use the flexible Dent RoCoil current transformers with legacy equipment that requires a 0-5A current input, with the TCA-5 high accuracy converter module.
TCA-5 5-Amp Converter Module for use with DENT Instruments RoCoil
Flexible Current Transformers (CTs) give a clear-cut advantage over conventional split-core or clamp-on CTs, but they do not provide the 0-5A outputs required by many applications.
The new TCA-5 from Dent Instruments fulfils this 5 amp output requirement in the marketplace.
The Dent Rocoil TCA-5 delivers the flexibility and ease of installation of the RoCoil current sensors to applications using power meters with 5A current transformer input.
Those who use 5 amp current input power meters will now be able to take advantage of the easy installation, high accuracy and broad current range coverage offered by RoCoil flex probe CTs.
The RoCoil TCA-5 is factory-calibrated to work with DENT RoCoil CTs (131mV/1000A). It is a DIN rail or panel mounted device requiring an external 48 VDC power supply. The RōCoil TCA-5 has four selectable current ranges:
500, 1K, 2.5K, and 5K amps and selectable frequency for both 50 and 60 Hz systems.
AC/DC 48V Power Supply (at the right side of the picture)
The RoCoil TCA-5 requires an external 48 VDC power supply for operation.
Two versions of the power supply are available:
a 120/240VAC “low voltage” version and a 200/500VAC “high voltage” version.
The power supply is provided as part of the RoCoil TCA-5 kit or may be ordered separately.
Selectable Current Ranges and Frequency
The RoCoil TCA-5 has four selectable current ranges: 500, 1000, 2500, and 5000A.
The range is changed using a switch on the front of the device. See Current Ranges table (left) for current range information.
A separate switch on the front is used to change the frequency between 50 and 60 Hz.
The wire that connects the RoCoil TCA-5 to the power meter is supplied by the user. Linearity and precision are maintained by using the correct output wire size.
The maximum allowable output impedance (or burden) of 70 m-ohm plays a critical role in the selection of output wire size and the allowable distance between the power meter and the RoCoil TCA-5.
The voltage drop allowed by the output circuitry (i.e., the voltage drop due to current flowing through the sum of the wire resistance and meter burden) is 350 mV RMS or 1.75 VA.
The RoCoil TCA-5 is intended to be wall mounted with the output terminals facing up.
Three RoCoil current sensors will typically be installed inside the service panel at the feeder or around the branch circuit of interest.
The RoCoil TCA-5 can be mounted as a panel unit using slide-out tabs on the back or mounted on a 35 mm width DIN rail (a 10″ section of DIN rail is included when ordered as a kit).
The TCA-5 module only comes in a 3 phase version. There is no single phase version.
It will only work with DENT Instruments RoCoil CTs.
It comes into it’s own with the new CT-RXX-4A-U series of RoCoils,
with accuracy of <0.6% over the range 10% to 100% of FSD.
The linearity is also <0.1% over the range of 10% to 100%.
All RoCoils are individually tested at the factory, at 10% & 100% FSD, prior to shipment, to ensure they comply.
The TCA-5 comes complete with DIN rail mounting strip, which also mounts the external power supply.
The 48Vdc power supply comes in two versions, for single phase (A-N) & three phase for (phase-phase) delta supplies.
The great feature is that it has a mechanical range switch on the front cover, which can set the 0-5A output to represent an input range of 500A, 1000A, 2500A, & 5000A, with full resolution.
There is also a switch to select 50Hz or 60Hz supply frequency.
No software or PC set up required.
This product is only for applications where a Rogowski type CT is required to provide a 0-5A output for existing installed equipment, that will only accept a 0-5A input signal, such as metering applications.

NOTE WELL: The secret to the successful application of this product is getting the unit mounted physically close to where the 0-5A output is required. Because of the higher 5A signal, customer’s cable size between TCA-5 & metering etc. is critical, and the manuals instructions & suggestions as to cable sizing is very critical.
