Spellman standard supplies can be run at maximum voltage, maximum current, and maximum power continuously with no adverse affect on performance or reliability. Each supply we sell is burned in at full rated voltage and full rated current for a minimum of 12 hours. All of our supplies are designed to meet a set of Spellman Engineering Design Guidelines that dictate all appropriate internal component deratings. Designing to these guidelines provides a supply with more than adequate margins, so there is no need to derate our supplies below our specifications.
