Ultimate Guide to Understanding Power Supply
Efficiency= output power/input power Expressed in percentage, power supply efficiency gives you a tentative idea of how much AC power the
In general, “efficiency” refers to the ability to accomplish a task or achieve a goal with the least wasted time, effort, energy, or resources. It measures how effectively inputs (such as time, labor, or materials) are converted into outputs (results or products). There are three major reasons that power supply efficiency is important to the user.
The EPA estimates that external power supply eficiency regulations implemented over the past decade have reduced energy consumption by 32 billion kilowatts, saving $2.5 billion annually and reducing CO2 emissions by more than 24 million tons per year.
Low-voltage external power supply means an external power supply with a nameplate output voltage less than 6 volts and nameplate output current greater than or equal to 550 milliamps. Basic-voltage external power supply means an external power supply that is not a low-voltage power supply. Direct vs indirect operation EPSS
nameplate output voltage less than 6 volts and nameplate output current greater than or equal to 550 milliamps. Basic-voltage external power supply means an external power supply that is not a low-voltage power supply EPSs DoE Level VI also defines power supplies as direct operation and indirect operation products.
The efficiency of these power supplies, mainly utilizing linear technology, could be as low as 50% and still draw power when the application was turned off or not even connected to the power supply (referred to as “no-load” condition).
While many countries are establishing voluntary programs harmonized to the international eficiency marking protocol system first established by Energy Star, the following countries and regions now have regulations in place mandating that all external power supplies shipped across their borders meet the specified eficiency level:
