GRADIENT
AMPLIFIERS - BFA AND BFH SERIES
SPECIFICATIONS
- BFH GRADIENT AMPLIFIER
The
BFH linear gradient amplifiers provide a current of +/-20A, 40A, 60A and 100A per
channel at +/-95V and are available in 1 channel and 3 channel versions.
Please
see also the high power gradient amplifiers, models BFH-266 and
BFH-280.
