![]() ![]() One higher (and less common) voltage specification found in industrial applications is 277 Vac. The minimum standardized range value of 85 Vac is derived from allowing a 15% voltage droop of 100 Vac, while the 264 Vac maximum range value is derived from allowing operation at 10% above 240 Vac. Japan is a country with one of the lowest nominal input voltage requirements (100 Vac) while the UK, Canada and the US have among the highest nominal input voltage requirements (240 Vac). There are specifications for different countries, but they are similar enough that the single specification range can meet the needs of most applications. The required input voltage operating range for most low or medium power ac-dc supplies is standardized throughout the world to 85~264 Vac. The user should verify the ac input voltage range of the power supply is compatible with their target markets and specified application. This includes the ac input range and the dc output specifications. When selecting an ac-dc power supply, the primary consideration is determining the system power requirements.
