The Bonfiglioli Inverter S2U is now also available in protection class IP66 with higher performance. The compact plug-and-play converters for single-phase 230 V and three-phase 400 V networks consist of three motor sizes from 0,4 to 18,5 kW. They are suitable for applications in harsh environments. The heat sink has been designed specifically for extreme environmental conditions such as dust, moisture and cleaning chemicals.
They also have an 32-bit processor with advanced IGBT power switching. Built-in PID controllers and PLC functions regulate frequency, pressure and air volume, for example in heating ventilation and air conditioning applications. The built-in EMC filter according to IEC / EN61800-3 ensures very low electromagnetic interference and enables safe operation. The inverters feature slip and torque compensation, emergency stop function, a carrier frequency of 1-16 kHz, which automatically changes according to the temperature function and an integrated brake chopper and a special firemode for fan applications.
Combining robustness and intelligence, the S2U IP66 range is used in applications such as pumps, fans, intelligent conveyors, textile machinery, material handling, woodworking, and food and beverage industries.
