Bonfiglioli's well-proven S2U inverters are now also available at higher power and with an IP66 protection rating. The compact S2U IP66 Plug & Play inverter for single-phased 230-volt networks and three-phased 400-volt networks comes in three sizes with engine power ranging from 0.4 kW to 18.5 kW. The new S2U IP66 inverter series is particularly suited to applications that require high resistance to environmental impacts, as well as those that require high braking power without braking resistor, and a high torque at low speed such as packaging machines, textile machines, material handling, woodworking machines, pumps, fans, and many more. The heat sink was designed specifically for extreme environmental conditions such as dust, humidity, and cleaning chemicals. Due to the high protection rating, the robust and highly cost and energy-efficient inverters remain completely unaffected by even the most adverse of conditions.
