SEW-Eurodrive is launching a compact and low-cost series of frequency inverters.
The Movitrac LT is suitable for low-power variable-speed applications such as fans, pumps, machine tools and conveyors. It is available in two frame sizes. The series comprises single-phase 230V units up to 2.2kW and three-phase 400V units up to 4kW.
The combination of keyhole mounting and intuitive contactor-style wiring connections for motor output and power supply make both mechanical and electrical installation easy. The use of 14 standard-configuration parameters streamlines setup time. In many basic applications the factory default settings can be used.
A keypad and LED display allow local control and programming of the MOVITRAC LT inverter. 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.
The series has programmable I/O for maximum flexibility, the option of silent motor running with 32kHz quiet switching. Cold plate' heat sink technology is available, along with a radio frequency interference (RFI) filter that results in C-tick compliance. It is rated to 50°C ambient temperature and will withstand 150% overload for 60 seconds.
