Ingress protection added to drive peripherals by encapsulation

The problem arises when there is a design or maintenance reason for not housing external input or output chokes or brake resistors in a control cabinet. Encapsulation also means that the products can easily incorporate water cooling, either by affixing a cold plate or with integral cooling channels.

The tendency is to use drives which have an IP65 rating and can be used as standalone devices without needing integration into control cabinets. This means that cost effective drive installations can be fitted much more quickly and with great flexibility. However, problems occur when external input or output chokes are fitted, or when the application requires the use of a brake resistor.

 

"REO solves this problem by offering a range of braking resistors, input and output chokes and even sine wave filters in ingress protection ratings up to IP65, matching that of the drives that they are likely to be used with,” says Steve Hughes, managing director of REO UK. "By either partially, or fully, encapsulating units and providing appropriate terminal boxes, REO is able to solve problems that other manufacturers simply can’t. In addition to this, most of these units can be built according to UL insulation and encapsulation systems and so can be used in the US.”
