The MOVITRAC LTE-B frequency converter in an IP55 housing from SEW-EURODRIVE offers simple, user-friendly handling via keys and a 7-segment display. The IP55 plastic housing protects the drive electronics from dust and moisture. Built-in line switches, selector switches, and setpoint potentiometers for setting the direction of rotation and speed are available as options. This converter is available in three sizes with power ratings from 0.37 to 7.5 kW. The permitted line voltages are 115 and 230 V for single-phase systems and 230 and 400 V for three-phase systems. A special advantage is the option to operate it on an earth-leakage circuit breaker in compliance with EMC requirements.
