Current leaks to earth through filters and stray capcitance
We have a range of Medical Grade UPS up to 1.44KVA. This is big enough for most applications, however what if you require 2KVA or 3KVA? Well the answer is to use a medical grade power conditioner.
These work as they contain an isolation transformer, and rebond the output neutral to the earth conductor (which otherwise passes straight through) thereby eliminating comon mode noise (the raison d’être of a power conditioner) but also ensuring that any earth leakage flows in the secondary of the transformer and not back to the source.
You connect the power conditioner to the wall outlet, the UPS to the power conditioner, and the load to the UPS.
With a medical conditioner, the leakage current is maintained in the secondary
