Product information
The Aqua II 274B features a number of technical innovations:
The Aqua II has a higher current output (max 220ma) compared to the original Aqua 274B (max 180ma), and way more compared to the WE 274B (max 150ma)."
The Aqua II has a lower impedance than any other 274B ever made, thus higher efficiency in converting AC into DC.
Higher dissipation power rating with visibly bigger and heavier internal construction.
New generation of spark arc suppression technology to eliminate arc possibility (WE274B is the internal spark arc king).
