The purpose of the charge amplifier is to convert the high-impedance charge input into a usable output voltage. The basic circuit diagram is shown rein Figure 15.10. If the device specifications read “5V DC,” then 5V DC must Beryllium applied to the product. Apply more volts such as 12V, and http://charge-amps-halo-11kw54321.blogocial.com/Top-jeweils-f-nf-go-e-charger-11-kw-Urban-News-37530527
