I apologize if my queries sound silly, so pardon me. The truth is that I have used transformers in my work for a long time, but never bought it myself -- someone else bought the required ones as per my specifications. Now I have to buy some from an online store as Digikey, and am confused, with all details presented to me. I want a 120 V AC -> 9 - 0 - 9 Volt 2 Amp AC transformer. I am also comfortable with two
120 V AC -> 9 - 0 - 9 Volt 1 Amp AC transformers connected in parallel, as I have found this to be a very convenient configuration, both in terms of space occupied by the transformers as well as weight and cost. So I navigated to:However, a lot of the presented data confused me.
- Who is a reputed manufacturer ?
- What exactly is the 'Series' supposed to mean?
- Voltage Secondary (Full Load) Now I fully understand what "Parallel 9 V, Series 18 V" means, but why is '18V' listed below ?
- Same confusion as for item 3 above holds for Current Output (Max) list - Why for example is 'Parallel 1.02 A, Series 533 mA' listes at the top of the list, but later in the same list is the item '1.06 A' ? Even more confusing are items in the same list : '575 mA, 5 A, 6 A' -- are these some special type of transformers ? Could any electronics guru please help me clear all the confusion ? Thanks in advance for your help.
