AN ultra-compact and low-cost series of frequency inverter will be exhibited by global drive solutions group, SEW-Eurodrive , at September's Automate exhibition in Sydney. The MOVITRAC LT is ideal for low-power variable-speed applications such as fans, pumps, machine tools and conveyors.
Available in two compact frame sizes, the MOVITRAC LT series comprises single-phase 230V units up to 2.2kW and three-phase 400V units up to 4kW. The use of the latest power modules to achieve an ultra-small footprint, coupled with an innovative bookshelf design, minimises required cabinet space.
According to SEW-Eurodrive applications engineer, Darren Klonowski, MOVITRAC LT is extremely simple to use. The combination of keyhole mounting and intuitive 'contactor-style' wiring connections for motor output and power supply, make both mechanical and electrical installation easy. In addition, the use of 14 standard configuration parameters streamlines setup time. In many basic applications the factory default settings can be used.
"A mobile-phone style keypad and LED display allow local control and programming of the MOVITRAC LT inverter" said Klonowski. "Plus an integrated help card, featuring parameter descriptions and an outline of the wiring terminal layout, provides a ready reference that's more convenient than the complete user manual. This further facilitates operations and technical support."
The powerful functionality that sets the MOVITRAC LT series of frequency inverters apart includes programmable I/O for maximum flexibility, the option of silent motor running with 32kHz 'quiet switching', the availability of 'cold plate' heat sink technology, and the incorporation of a radio frequency interference (RFI) filter that results in C-tick compliance. The industrially robust unit is also rated to 50°C ambient temperature and will withstand 150% overload for 60 seconds.
The MOVITRAC LT will be on display at the SEW-Eurodrive stand at Automate 2005: stand C2, Sydney Showground, Sydney Olympic Park, September 13 to 15 2005.
