ZF120A VI Series Desktop Type / Wall Mouned Power Supply

Published in: 2017-09-04

In February 2016, the U.S. Department of Energy (DoE) enacted energy efficiency regulations that require external power supply to meet Energy Efficiency Level VI. To meet the current average efficiency and no-load power requirements mandated by the US Department of Energy (DoE) under the Level VI standard and it also conforms to the trend of green, environmental protection and energy conservation, the new generation Level VI desktop type power supply 60W VI series and 72W VI series of Zhen Huan, has received positive feedback from America market since it was firstly announced in 2016. In order to further fulfill the application demands for the lower out wattage and higher wattage, Soon after Zhen Huan is pleased to launch the new wall mounted power supply 12W/ 24W/ 36W VI series and desktop type power supply 12W/ 24W/ 36W/ 84W/ 100W/ 120W VI series.


Level VI series follows the features of Level V, accepting 90~264VAC full range input, providing complete 4.2V~48V output models. The design is approved for UL/cUL, CE, GS, RCM, KC, CB, PSE, CCC marks and meet the radiated and conducted emission requirements for FCC Part 15B Class B. The power supply use eco-friendly materials, research and development of new type classfiber PCB and using original authentic EMI component for filter inductance、safety capacitor. Protections for over voltage, over current and short circuit are also included.


The performance thresholds of DOE VI are summarized in the table below:
