Glossary: Efficiency

''Efficiency'' describes the ratio between the output power and the input power of a power supply. The difference between input and output power is converted into heat as loss.

The efficiency values are usually given for nominal voltages. Additionally, the PULS data sheets include characteristics from which the efficiency values at partial load or at various input voltages can be read out. High partial load efficiency is becoming ever more important as a power supply rarely is permanently operated at full load.
Latest technology in power supply design enables an economical realization of efficiencies up to 96%. At PULS, these technologies are consistently followed, improved and offered to users in various device families. High efficiency values ensure low warming, long service life and high reliability of all components in the control cabinet. It also enables devices to be designed and built as small as possible.
