It can be increasingly difficult to find a manufacturer who holds stock when you are looking to retrofit existing DC motor applications with a discontinued part. This has been exacerbated recently by a major drives manufacturer stopping production of DC motor controllers above a certain rating (500HP / 350kw about 850 amps).
SO HOW DO YOU SOURCE A SUITABLE ALTERNATIVE?
Size consideration is vital, especially when retrofitting, as you’re often constrained by the size of the space left by the DC drive you’re replacing or upgrading.
All of our drives are designed and manufactured to be more compact than most of the installed base of DC drives you’ll find. See how easily you can retrofit Sprint Electric DC Motor Controllers with our retrofitting size chart here.
You might be concerned with essential functionality? Whether it’s the number of I/O options, the pre-configured software options, or the space saving frame sizes, you want to be sure you’re choosing the right digital DC drive.
We have made a simple comparison guide to help you compare the Sprint Electric PL/X range against the digital DC drives from four other manufacturers. Here you can explore the differences in:
- Standard Software Functions
- Inputs/Outputs
- Protection
- Field Control
RECENT EXAMPLE OF DC DRIVE REPLACEMENT
