Hi all.(adsbygoogle = window.adsbygoogle || []).push({});

I'm hoping someone can help me out on a (for me) tricky little issue.

We are to use a communication module that we know will draw 5amp and must be supplied via a UPS. Tricky bit is that its 3.5km away so we need to step up the voltage at source and step down again at load. 400Vac is to be stepped up to 1000Vac (50Hz) and back down again at load. And now to the question, how do I calculate the load on the UPS with this setup?

Grateful for help.

Regards

Tony
