Input Protection

Posted on 15-Jun-2016 11:57:41

Input protection is implemented in power supplies and DC/DC converters to ensure safe operation. The input fuse fitted within a power supply is not intended to be field-replaceable, it is rated such that only a catastrophic failure of the power supply will cause it to fail. It will not be cleared by an overload as the power supply will have some other form of overload protection, usually electronic. The fuse will often be soldered into the PCB rather than being a replaceable cartridge type fuse.

Determine System EMI Characteristics Early in System Design Phase

Posted on 15-Sep-2015 14:00:00

Often in the commercial, industrial, medical and military industries, system engineers wait until system qualification before addressing critical functions for EMC and EMI compliance to relevant standards. The most common mistake is the belief that a power supply with EMI compliance certifications to required system standards will ensure system EMI compliance. This is all too often proven to be an incorrect assumption.
