RSBT 45MM MODBUS SOFT STARTER: MORE INTELLIGENCE FOR THE NEW GENERATION OF HVAC SYSTEMS

Metering functions, remote control and additional flexibility for optimised performance.

Lainate, January 2017 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacture and marketing of electronic equipment, today presents the new RSBT 45mm scroll compressor soft starters with Modbus communication.

Energy efficiency regulations in buildings are driving the need for more intelligent HVAC systems. The integration of such systems into a building management system (BMS) triggers the need to get more information down to component level. As the compressor is typically the largest energy consumer in a heat pump or chiller, measuring the energy in real time makes it possible to monitor the overall efficiency of the system. Apart from this, the data that the RSBT Modbus can measure also facilitates after-sales activities such as quicker fault finding. We also offer the possibility of modifying a limited set of parameters, thereby giving our customers further flexibility to customise the product for specific applications. Our soft starter configuration software (SCS) provides a very easy-to-use tool to visualise in a graphical way the variables that are measured by the RSBT.

Our customers need more information from the components that are used in their HVAC systems. The RSBT 45mm now features Modbus communication to meet this requirement. The variables measured by the RSBT soft starter include energy related variables, so allowing further cost saving for our customers as more functions can be integrated into one single unit. With the introduction of serial communication on the RSBT 45mm soft starters we envisage maintaining our leading position in the HVAC market by providing more intelligent and user-friendly solutions.

“The RSBT 45mm is a unique solution that provides several types of data so that the user may remove additional components from the electrical panel, resulting in cost and space saving,” says Jason Demicoli, International Product Manager. “With this launch, Carlo Gavazzi continues to expand and strengthen its product range targeted at the HVAC market segment, offering a more advanced device with a number of intelligent features suited to smart HVAC systems.”

Designed by our Competence Centre in Malta, this soft starter series has been specifically developed to be used in HVAC system applications such as chillers, roof-tops and heat pumps.

EM210 MV AND ROG4K: THE EASY RETROFIT SOLUTION FOR ENERGY EFFICIENCY

High accuracy in a very wide range - from 20 to 4000 A - by means of the combination of the compact analyser EM210 with the Rogowski coil ROG4K.

Lainate, December 2016 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacture and marketing of electronic equipment, presents the energy analyser EM210 MV, now compatible with our new range of Rogowski coils, the ROG4K.

Thanks to the EM210 MV built-in signal integrator, the ROG4K coils can be directly connected and an external integrator device (and relevant additional power supply) is not required, allowing fast and cost effective installation even in critical applications.

The ROG4K can cover a wide range of primary currents, from 20 to 4000 A guaranteeing class 1 accuracy.
“The EM210 MV is the ideal solution for panel builders, system integrators and ESCOs as its features help any retrofit operation, even in complex situations. A wide range of possible applications can be satisfied thanks to the possibility of managing both standard 333 mV current sensors - such as the CTV series - and ROG4K coils by simple programming” says Andrea Bernardi, International Product Manager. “This launch confirms the EM200 series as the range of products which simplify the work of the installers in terms of installation time, space saving and reducing errors.”

The EM210 MV and the ROG4K series have been designed by our Competence Centre in Italy in order to meet retrofit requirements in the Conventional energy market and energy efficiency requirements in the Building automation and light/medium industry markets.
