Dent ELITEpro XC poly-phase power data loggerA high accuracy and versatile 3-phase energy/power data logger
Dent ELITEpro XC poly-phase power data logger
Energy Data Logger: A high accuracy and versatile 3-phase energy/power data logger, which measures and records many power parameters, with 4 Analogue Inputs for additional sensors such as temperature.
Manage your energy usage by measuring, logging and analysing electrical loads, plus physical measurements such as temperature.
The ELITEpro XC is a recording poly-phase energy meter, capable of measuring up to:
- four single-phase loads, or
- two three-phase Delta loads, or
- one three-phase Wye load…
- plus up to 4 analog environmental sensors.
- Allocating electrical costs by sub-metering process lines, departments, tenant spaces, or entire buildings;
- Preparing baseline studies to identify energy usage and consumption – ‘when and where‘ ;
- Institute management protocols for conserving energy based on data;
- Measuring performance to verify results, towards reducing operating costs.
Connects 4-channels of AC current sensors (see current transformers below), and
3 channels of AC voltage (600V AC or DC line to line), plus
4 channels of analog DC sensors (4-20mA or 0-10V DC).
The “PhaseChek” LED indicators ensure correct CT orientation at installation.
Will measure, store and report:
Volts, Amps, Amp-Hrs (Ah),
kW, kWh, kVAR, kVARh, kVA, kVAh,
Displacement Power Factor (dPF).
All parameters for each phase, and for system total.
High Accuracy: better than 1% (<0.2% typical) for V, A, kW, kVAR, kVA, PF
Great Resolution: 0.01 Amp, 0.1 Volt, 1 Watt, 1 VAR, 1 VA, 0.01 PF
Large Data Storage: 16MB of memory stores 3.6 Million data points
With 3 single phase 20A lighting circuits, logging only Power (kW) and Energy (kWh) of each circuit, at 15 minute intervals, the logger’s memory will fill up after 13 years.
When connected to a PC running ELOG software, It will calculate harmonics from DC through the 63rd then report total harmonic distortion (THD), crest factor and peak voltage & current.
Communicate via USB port, Ethernet port, or via wireless LAN (WiFi) or Bluetooth systems.
Analog Inputs on the new ELITEpro XC
The ElitePro XC has the same physical casing as the ElitePro SP, except it now has twice as much on-board memory, with 16Mb, and has the addition of four (4) analogue DC inputs.
The analogue inputs allow the ElitePro XC to log other engineering parameters, using industry standard sensors with DC voltage or DC mA current outputs.
The four (4) DC analogue inputs can be configured as 0-10VDC, 0-20mA DC, or 4-20mA DC. They can also be scaled for any real-world units & span.
These are very useful where environmental parameters such as outdoor temperature, or other parameters like flow, pressure etc., need to be logged at the same time as the electricity consumption.
ELITEPRO XC ANATOMY
The Logger that Pays for Itself
Our research & feedback has shown a few specific things about the ElitePro XC:
- It is as powerful as a Fluke equivalent, but at a much more cost effective price.
- Energy audit customers advise the ElitePro XC loggers pay for themselves in 2-3 months.
- We have found the support needed for this product is very low.
- Unlike a lot of products, the power of the ElitePro is not the logger itself, but the data & information it can produce with a minimum amount of effort and expertise.
Notes on Wireless models
There are several things to note with regard to the ElitePro XC models with wireless connectivity.
The wireless facilities are designed specifically by DENT for setting up, and verifying real-time readings. They are not intended for downloading data from the ElitePro XC.
With 16MB of data, downloading over wireless can be a long drawn out exercise, if the logger is full. It can take 30-60 mins, and if you get a wireless drop out part way through, it can be very frustrating.
Switchboard environments, where the ElitePro XC will be mounted, are notoriously electrically noisy. The thickness of switchboard cabinets can vary, and signal strength can vary widely.
We strongly suggest that all downloads of data be carried out with the USB or Ethernet comms connection.
We have found that signal strength with Bluetooth is really not good in electrically noisy environments, and we would not be promoting its use, other than in open spaces in non industrial applications(e.g. house energy audits may be OK).
The Bluetooth model delivery time is 7-10 days.
The WiFi models with internal & external aerials are a totally different matter.
The ElitePro XC, with internal aerial is the most popular, & we stock these on the shelf.
From tests we have carried out, there is not a lot of difference between the signal strength performance of the ElitePro XC with internal aerial, and external aerial. The XC with external aerial, is really only applied in fixed installations, where the aerial is needed outside a heavy cabinet, so that a good signal can be obtained.
All ElitePro XC energy loggers carry the new Australian RCM safety & emission mark requirement.

ElitePro logger Memory Details
The ElitePro logger has too many variables to be able to provide a quick & easy calculation as to memory capacity in days, hours & minutes.
ELOG software provides a convenient feature that calculates the length of time required to fill the memory for any setup table.
The feature is dynamic, so that any time any parameter in setup table affecting the memory duration is changed, the “Calculated Days Until Memory Exhausted” is updated.
This allows the operator to know in advance how long the memory will last.
The ElitePro Integration period affects the memory capacity. It has
integration periods of 1, 3, 15, 30 seconds, 1, 2, 5, 10, 15, 20, 30 minutes, & 1, 12, & 24 hours. * More about this below
The ElitePro has four (4) channels each of which will log up to six (6) parameters of volts, amps, kWatts, KVA, P.F. KVAr
Each of these parameters can have four measurements logged for each integration period.
They are min, max,average, instantaneous.
In addition the ElitePro has two (2) virtual summation channels (no external connections).
One of these is typically used to measure totals or averages of the individual phase parameters.
With all 6 channels activated and all parameters selected for min, max, average, & instantaneous,
the ElitePro will log a staggering 144 parameters.
In addition there are alarm settings for each parameter, channel descriptor, and channel comments,
VT ratio, CT ratio, that can be set, all using varying amounts of memory.
* The default integration period is fifteen minutes. The choices are 1, 3, 15, 30 seconds; 1, 2, 5, 10, 15, 20 and 30 minutes; 1 and 12 hours; 1 day.
This tells the logger at what time intervals data is to be stored in the memory.
For example, if the integration period is set for 30 minutes and average watts is being monitored, then every 30 minutes the logger records the average power use (watts) for that channel over the preceding 30 minute interval, based on about 600 measurements of the monitored power draw. If Maximum (and/or Minimum) values are being recorded the highest (and/or lowest) of those 600 readings are also saved.
The ElitePro XC mated with a set of RoCoil CTs, is a powerful tool, with an ampere recording range of 5-5000 amperes.
However, we do suggest that where clients are using their ElitePro XC to measure currents up to a couple of hundred amperes, that they employ one of the DENT Hinged Mini or Midi ferrite split core CTs, to attain maximum resolution of their readings.
Most ElitePro XCs are now purchased with a set of RoCoils & a set of smaller CTs.
Prices include all accessories & software (listed above), except CTs. Please see below for CT’s to suit.

If a client hires a logger for a week or more, to try it out, and subsequently purchases a new ElitePro XC within one month, we will deduct the hiring cost from the price of the logger.
Current Transformers for ElitePro XC and SP
These CT’s are all suitable for ElitePro XC / SP loggers. Prices do not include GST and may change without notice. (11/15)
Notes on RoCoil Current Transformers (Rogowski Coil) for ElitePro XC (CLICK TO VIEW)
Rogowski Coil Current Transformers have no metal cores which make them extremely flexible and light weight.
Because they lack a metal core, Rogowski coils have very low phase shift error, can be used on very high currents, and are suitable for highly distorted AC waveforms.
These “rope” style CTs are designed to take measurements where standard current sensors cannot.
The DENT RōCoil™Current Transformers have been designed for accurate non-intrusive measurement of
AC current, pulsed DC or distorted waveforms where conventional rigid core CTs are unsuitable.
This type of sensor may be used to measure AC current over a wide dynamic range and from 20 Hz to 5 kHz.
Note: Some applications may require use of integrator/amplifier such as the Dent TCA-5 (further down this page). See also RōCoil mV™ below.
- Various Lengths: 40 cm (16″), 60 cm (24″), 90 cm (35″), 120 cm (47″), and extra long 72″
- Output Signal (di/dt): 131 mVAC/1000A @ 60 Hz, 109.2 mV/1000A @ 50 Hz
- Current Range: 5 – 5000A AC*
- Accuracy (typical): < 0.6%**
The RoCoil CTs have recently changed slightly in their specification. They are slightly thinner than the previous models, but now have a better accuracy spec., improved from 1% to <0.6%. They also have better linearity over the range 10% to 100% of full scale. They are now all individually tested at the factory at 10% & 100% of full scale, to confirm they comply, & that linearity is within 0.1%. They are simply the best commercially available Rogowski coil CT currently available in the world, for this kind of application.
The original RoCoil MV CTs had a slight disadvantage, in that they had to be externally powered, & were as a result, a 4 wire device. The advent of the PowerScout & ElitePro XC, able to directly connect to a 2 wire RoCoil, has eliminated those concerns.
Added to that, the RoCoils have proved to have great accuracy, and now have a remarkable turn down ratio & range from 5 to 5000A, they are in many places being used where a traditional 500A clamp-on CT would have been previously applied.
RoCoil models suitable for the ELITEpro XC and SP, and for PowerScout:
The DENT RōCoil™Current Transformers have been designed for accurate non-intrusive measurement of AC current, pulsed DC or distorted waveforms where conventional rigid core CTs are unsuitable. This type of sensor may be used to measure AC current over a wide dynamic range and from 20 Hz to 5 kHz. Note: Some applications may require use of
integrator/amplifier. See also RōCoil mV™.
