Lake Shore Model 642 Electromagnet Power Supply User’s Manual Output Architecture (Continued) The Model 642 output architecture relies on low noise, linear input and output stages. The linear circuitry of the Model 642 permits operation with less electrical noise than switch-mode electromagnet power supplies. One key benefit of this architecture is CE compliance to the electromagnetic compatibility (EMC) directive, including the radiated emissions requirement. Output Programming Th
