What are the new energy conservation standards for external power supplies?The U.S. Department of Energy (DOE) has recently proposed new energy conservation standards for External Power Supplies (EPSs). These proposed standards, known as Trial Standard Level 4 (TSL4), aim to tighten energy efficiency requirements across all types of EPSs. TSLs are a tool used by the DOE to set energy conservation benchmarks.
Do external power supplies have a power efficiency mandate?At a global level, mandates for power efficiency exist for most consumer electronics and home appliances. External power supplies have had regulations dating back to 2004, when the California Energy Commission created one of the first mandates for efficiency of external power supplies used to power appliances or consumer electronic devices.
Is the DOE efficiency standard mandatory?The DoE efficiency standard is mandatory. Both standards segregate their requirements into power and voltage ranges. In this post, I’ll focus on the low-voltage (<6V) and lower power (<250W) efficiency and standby power requirements. Table 1 and Table 2 list the CoC and DoE standby power requirements for low-voltage/low-power EPSs.
What are the new standards for power supply design?In 2014, the US Department of Energy formalized their newest mandatory standard and the EU’s voluntary Code of Conduct version 5 took effect. This white paper briefly explains the US and EU’s new standards and what they mean to power supply designers.
Which countries adopt voluntary and mandatory external power supply standards?Since then, the US, European Union, China and other countries adopted both voluntary and mandatory external power supply standards as part of energy conservation legislation. Table 1 shows a breakdown of some of the current voluntary and mandatory standards by region.
