Hello and greetings.

Greetings from the arctic region of Boulder, Colorado and Happy New Year from all of us at Continental Control Systems.

I hope that this finds you and yours safe, happy and healthy after an enjoyable holiday season. The first quarter of 2014 promises to be busy as our business level grew steadily throughout the last months of 2013. We had a great year and sincerely thank you for your business and the confidence that you have in our products.

I have included additional product information about the Rogowski Coils, our recent ANSI C12.1 certification by MET Labs and news of the BTL mark that we can now display alongside our WattNode BACnet products in this newsletter. I have included links to our website as well as contact information for many of us should you be interested in additional information – please do not hesitate to contact us directly if we may be of any assistance to you. As always, I hope that you find this newsletter informative and of interest. If for any reason you wish to be removed from our private email list, either let me know directly or opt out by using the link below.

Once again, we thank you for your business and look forward to working with you in 2014.

The WattNode® BACnet® is now BTL Listed

The WattNode BACnet meter has received BACnet Testing Laboratory (BTL) certification. The meter has passed a series of rigorous tests conducted by an official BTL facility, earning the right to display the BTL Mark.

For automation and control system designers, the BTL Mark on a product signifies that it is fully compliant with BTL’s demanding performance standards and that it correctly implements the BACnet features claimed in its BTL listing.

BACnet is a registered trademark of ASHRAE. ASHRAE does not endorse, approve or test products for compliance with ASHRAE standards. Compliance of listed products to requirements of ASHRAE Standard 135 is the responsibility of the BACnet International. BTL is a registered trademark of the BACnet International.

WattNode Revenue Modbus meter receives
ANSI C12.1- 2008 certification

The WattNode Revenue Modbus electric energy and power meter has been revenue- grade certified by MET Laboratories, Inc. to meet the C12.1-2008 requirements of the American National Standard Institute (ANSI).

In addition to the Modbus communications protocol, the compact and cost-effective WattNode Revenue meter line supports BACnet, LonTalk, or a pulse output. Models
are available for 120/208/240 Vac and 277/480 Vac applications. Each WattNode Revenue meter is calibrated using NIST-traceable equipment following the procedures specified by ANSI C12.1-2008 standards, and is supplied with a certificate of calibration.

CTRC Rogowski Coil Current Transformers

Because of it flexibility, the Rogowski coil is designed for large bus bars and irregular- shaped conductor bundles. Its small profile allows it to be used on conductors in tight spaces where rigid CTs simply won’t fit.

The UL-recognized CTRCs provide accuracies of ±1.0% from 5% to 120% of rated current, and are available in standard loads up to 6000 Amps. The Rogowski coil is offered in four standard diameters from 3.1″ round (loads to 1000 Amps) to 12″ round (loads to 6000 Amps).

The CTRC coil along with the signal conditioner is compatible with any of the WattNode energy meters providing accurate energy (kW) and power (kWh) production and consumption measurements.

Intelen integrates CCS smart meters

Intelen Inc. has announced the complete integration of Continental Control Systems’ WattNode® Modbus® smart meters series onto its energy monitoring and engagement platforms, bringing up the number of major smart meters’ brands the company can readily draw data from, to four.

More choice for businesses
Aiming to make energy monitoring as simple as possible for all businesses, Intelen recently completed the integration of CCS WattNode® Modbus® meters series to its platforms. Intelen’ solutions being compatible with even more meters means that businesses already equipped with smart meters, as well as businesses in the market for a complete energy management solution, will have even more choice to find a platform that really addresses all their energy efficiency monitoring needs without having to make price-based compromises.

Based in New York, Intelen Inc. aims to provide business and people with powerful tools that transform real-time energy data into information that makes sense and drives energy consumption reduction and efficiency through real, long lasting engagement.

Intelen Inc. currently offers three powerful integrated platforms that cover every energy consumption management need businesses may have, irrespectively of their size or industry: Intelen Building Monitoring offers real time, accurate energy consumption analytics that provide actionable insights into when and where energy is consumed within a building or its sections. Intelen Building InSights provides businesses with a powerful tool to design, evaluate and stay on top of energy savings retrofits and upgrades. Intelen Building InGage is an innovative platform that uses games and awards to drive energy consumption awareness and reduction among the occupants of a building. Intelen Inc also offers a custom PV monitoring tool and has more energy management applications in the pipeline.

Tech FAQs

What is the difference between 3D and 3Y WattNode meter models?

The ØA, ØB, and ØC voltage connections on a WattNode meter are used for two things: measuring the line voltage, which is needed to calculate energy, and to supply a few watts of power to operate the meter.

The “3D” and “3Y” characters you see in WattNode meter part numbers indicate how the meter gets its operating power. The “D” refers to a delta type electric service and the “Y” refers to a wye type of electric service. Either style of meter can measure 1, 2, or 3 phases depending on the number of current transformers (CTs) that are used. Either style of meter can measure delta or wye loads. The key difference between delta and wye style meters is how they are powered.

Delta (3D) meters are powered from the ØA and ØB line voltage connections. A neutral connection is not required, but you must connect the safety ground because it is used as the meter’s voltage measurement reference point. Delta model WattNode meters can be installed at any location where there are two phase conductors present. Delta meters must be used for four wire delta or grounded delta services. Additional information on these types of services is available from the Four Wire Delta Circuits and the Three-Phase Grounded Delta Circuits pages on our website.

Wye (3Y) meters are powered from the ØA phase and neutral connections. A safety ground connection is not required because the meter’s voltage measurements are referenced to the neutral connection. Wye model WattNode meters can be installed at any location where there is one phase conductor and neutral present. The phase conductor can be any of the three phases in the system. Wye meters must be used for single phase (120, 230, 277, and 347 volt) applications, when the meter is installed near the load and only one phase voltage and neutral are available.

Note that the ØA, ØB, and ØC phase voltage inputs are arbitrary labels. Unlike a three phase motor where phase rotation is important, the voltage inputs to a WattNode meter can be connected to any phase voltage, in any sequence. Remember that your CTs must be installed on the same phase conductor as the voltage input for that channel (ØA, ØB, or ØC).

Because the power supply in a wye meter operates at a lower voltage than a delta meter, wye meters cost about $30 less than delta models. If you are not sure that there is a neutral present at the location where the meter will be installed, order a delta model.

For a listing of the minimum and maximum power supply voltages for all WattNode meter models, please refer to the Operating Voltage Ranges page on our website. For information on the different types of utility services, see the Electrical Service Types and Voltages page.
