Series S-NA and SL-NA (flat or low profile) of PCB mountable power transformers
are developed in order to satisfy the demands in different applications. Our
products have perfect index of electromagnetism characteristics, sufficient
primary over-voltage capacity, wide range of adaptive ambient conditions, high
safety standard and high reliability. The series are called “Argent Angel?
because of their silver gray color and their trustworthy power giving
capability like angels. It has been proven the ideal choice in all applications
in process control, war industry equipments, automation instruments, office
equipments, scientific research academies and much more.
