TEC's new hard case…

31 October 2019

The new TECDrive IP66 VSD offers efficiency and motor control for demanding environments.

TEC Motors has introduced an IP66/NEMA 4X rated version of its general purpose TECDrive Variable Speed Drive (VSD). Offering the same energy savings, ease of installation and intuitive user experience as the standard model. The IP66 TECDrive VSD is specifically designed for tough applications where durability and reliability are paramount.

The IP66 TECDrive VSD has been designed to work outside the control cabinet environment and can be mounted almost anywhere. It will withstand outdoor conditions and regular low-pressure washdowns thanks to its high ingress protection rating, tough polycarbonate enclosure and corrosion resistant heatsink. The enclosure is UV stable and impervious to dirt, grease, oils and weak acids, it also has a wide operating temperature range from -10°C to 50°C.

A key advantage is its ease of installation, allowing general purpose users to start benefitting from energy savings and motor speed control quickly. There is a clear LED display with waterproof buttons for basic settings, plus, the option on every model to include a manual run/reverse switch and speed control potentiometer. There are four frame sizes available with power rating from 0.37kW single phase, up to 22kW three phase all available from UK stock.

An integrated isolator switch is another practical option which can also save time and money by avoiding the need for external electrical isolation. These features make the drive a really effective alternative to mechanical speed control on simple machines, avoiding the cost and maintenance required by belts, pulleys and gearboxes. For more sophisticated distributed control systems, the drives are network compatible with Ethernet, EtherNet/IP, CAN open and Modbus RTU.   

The IP66 TECDrive delivers sensorless vector control for all types of IE2, IE3 and IE4 motors. There are 14 basic operational parameters in addition to useful automatic industrial, pump and fan management modes. Industrial mode is designed for high starting torque, pump mode provides constant or variable torque while fan mode is optimised to meet the high efficiency requirements of HVAC systems. 

Operators can also specify the Bluetooth ‘Optistick Smart’ rapid commissioning tool, a plug-in data stick that is ideal for quickly copying, backing-up or restoring drive parameters remotely using a PC or smartphone. Remote keypads, RJ45 accessories for fast Modbus connections, Ethernet modules, external EMC filters, input chokes and output filters are all also available.
