SMP offers chokes with a protective paint coating according to IP66 which protects them from water and dust. The components are used to choke the current in inverters that are exposed to harsh ambient conditions, including rail vehicles or oil rig applications.

Advantages

The IP66 protection rating enables the chokes to be mounted outside the inverters. The advantage of this kind of mounting is that the heat generated by the choke is created outside the inverter, not inside it. A lower temperature inside the inverter eliminates the need to dissipate the heat using fans, which in turn saves energy. Another advantage of mounting them on the outside is that the inverter can be designed significantly smaller.

Applications

SMP has developed chokes with a protective paint coating for mounting outside the inverter even in applications on open water oil rigs, where exposure to intense sunlight, seawater, rain and chemical gases is expected. To simplify mounting outside the inverters, SMP also provides the chokes with special mounting fixtures. The choke and the mounting plate are both located outside the device, the connecting wires pass into the interior through a sealed opening.
