DTA71 / DTA72: THE NEW SERIES OF MOTOR THERMISTOR RELAYS

The over-temperature protection ensures continuous production process.

Lainate, July 2016 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufacture andmarketing of electronic equipment, today launches its new series of motor thermistor relays: the DTA71 and the DTA72.

They are motor thermistor relays able to monitor up to 6 motors temperatures by means of their internal windings PTCs. Thistype of control avoids false alarms which may cause interruptions in production, so considerably reducing expensive machinedowntime.

Thanks to the 35 mm housing width (Mini-DIN), the new DTA7x series can be installed onto classic DIN rails which are used in themajority of cabinets and electrical panels. The launch of these series also gives the opportunity to introduce other improvementssuch as universal power supply and bi-colour LED which, through different colours and blinks, indicates Power ON, PTC failures,Alarm and the ready to RESET state. 1 or 2 output versions are available in order to drive not only the motors but also the auxiliarydevices: the 2 output version provides, as well as the interruption of the motor supply, the additional signal for a lamp, PC or PLC.

“If compared to the existing similar products in our range, the DTA01 and DTA02, these new series of relays provide multi-voltagepower supply, enabling the reduction of the part numbers from 6 to 2, the mini-DIN housing and the “ready for reset” mode,”says Mark Wilkinson, International Product Manager. “We are expecting to increase our sales due to cost optimization and thepossibility of using these devices in applications where a standard DIN housing cannot be used.”

Designed by our Competence Centre in Italy, the DTA71 and DTA72 series are ideal solutions for pump monitoring. They can beuseful in all applications where motors are used, especially where overloads are frequent and may cause motor damage, suchas pumping stations in water treatment, conveyors in materials handling and chillers in HVAC systems.

RVFF SERIES: A COMPLETE RANGE OF AC DRIVES TARGETED AT INDUSTRIAL MOTOR APPLICATIONS

High performance and extremely short installation time.

Lainate, July 2016 - Carlo Gavazzi Automation, the international electronics group with activities in the design, manufactureand marketing of electronic equipment, today launches the new RVFF series of 3-phase drives.

The RVFF series of drives can be used with both AC induction motors and permanent magnet motors from 4.0 to160 kW (5.0 to 215 HP). They have several advanced algorithms for wider application coverage: advanced V/F control,SLV (Sensorless Vector Control) and Permanent Magnet SLV.

The on-board 32 bit microprocessor ensures a fast response time and hence a very precise load control.The RVFF is available in six frame sizes and can be used in 400 Vac, 3-phase applications.For the versions up to 55kW, an EMI flter is integrated, allowing use in applications where low noise emission is necessary.The approval EMI-EMS conforms to EN61800-3, CE conforms to EN61800-3 and EN61800-5-1 and they are alsoUL approved UL508C.

“The new RVFF ensures maximum performance and a signifcant reduction in costs. Its advanced network protocols forbuilding automation include BACnet, Metasys N2 and Modbus,” Wong Jie Hong, International Product Manager, states.“With this new range we aim to strengthen our position in applications where speed regulation of fans and pumps canprovide substantial energy savings and improved load control.”

This series has been specifcally designed for pumps and fan control in markets such as HVAC, Agriculture, BuildingAutomation and Water treatment.

Main technical features
• Integrated EMI flter – Minimizes disturbance and allows more space in the panel
• Modbus, BACnet and Metasys available as standard onboard communication protocol
• Intelligent built-in PID functionality - Provide simple sequential and logic control
• RJ45 interface – quick and easy connection to PC
• Advanced auto-tuning functionality
• Permanent magnet control
• RTC function, basic PLC – Effcient load control
• Automatic energy saving function – The output power changes in proportion to the load
• Removable LED keypad – increased installation ?exibility
• Integrated braking transistor up to 37kW
• Application specifc IC (ASIC) – avoids inrush current damage to IGBT chip
• 100Mhz 32bit processor – faster response time
• User-friendly PC programming software
