The simplest way to develop a highly reliable based on the power specifications above would be to over-specify every critical component to such a level that it would be virtually impossible for it to fail.
However, in reality, doing so would simply price the customer out of the market. The solution to this particular problem lies with extensive testing under a huge range of conditions to understand exactly what is required to deliver the performance and how the environmental conditions can impact on the driver performance. Whilst technical data and theoretical planning is important, there is no substitute for real life testing, especially in unpredictable or variable applications.
By carrying this out we were able to garner extensive data on the exact performance required and then specify the driver accordingly and choose the components appropriately.
