Devices that make patient contact require two means of patient protection (2 x MOPP) from the Mains Power Supply and devices that do not make patient contact require 2 x MOOP. A properly selected power supply will satisfy all necessary requirements for MOP. IEC 60601 identifies minimum creepages, clearances, and test voltages for each means of protection based upon the working voltage of the circuit as shown in the following table… Read more (view pdf) >>
