All In One Motor Controller, Includes Soft Start/Stop
Carlo Gavazzi RSHL

Current limit, supply and temperature monitoring!
Can replace traditional Star-Delta motor starters.

The RSHL Midi Smart is a compact easy-to-use AC semiconductor motor controller with which 3-phase motors with nominal currents up to 18A can be soft started and/or soft stopped.

The RSHL Midi Smart controls 2 phases only, while the third phase is continously connected to the load. Soft starting and soft stopping is achieved by controlling the motor voltage.

During normal running operation (<20A) the semiconductors are bypassed by internal electromechanical relays. Ramp profile, overload trip class, current limit settings and alarm parameters are user adjustable via the front panel.

Eight LEDs on the front panel indicate the states and alarms of the softstarter. The RSHL MIDI Smart includes an End of ramp auxiliary relay, Alarm auxiliary relay, and overtemperature protection. The RSHL Midi Smart has an integrated Current Limit and Overload Protection. The RSHL Midi Smart comes with an integrated heatsink and is ready to mount on DIN rail.

Carlo Gavazzi's 3-phase motor softstarter with electronic motor overload protection can replace traditional Star-Delta (Wye-Delta) motor starters.

The RSHL Smart Softstarter controls and protects three-phase induction motors rated up to 5Hp at 220VAC, 10Hp at 480VAC and 15Hp at 600VAC. Soft starting and stopping can be achieved with nine customizable (time and shape) voltage ramping profiles.

A current limiting starting option is also available. The built-in, manually adjustable, electronic overload can be set for either a Class 10 or a Class 20 trip characteristic and for manual or automatic reset. The RSHL Smart Softstarter can also monitor motors for overheating (via a PTC input), phase loss, sequence and inbalance. In addition to motor monitoring, the RSHL also monitors itself for overheating and internal failures.

The RSHL Smart Softstarter’s typical applications include the control of pumps, compressors, fans, hydraulic systems, conveyors, grinders, mills, mixers, circular saws, machine tools, presses, wire drawing machines, industrial dryers and washing machines, carousels, bottling machines and blowers. They carry the CE and RoHS marks, and are cUL approved – your assurance of a high quality and safe product.
