B1 for auto use

xecluded · 22nd May 2012, 10:13 PM

How would I use the B1 in my car or is it even possible. Thanks

The B1 uses a 18Vdc power supply at the jFETs.
The car has a 12V system that tops out at ~13.8V.
The B1 won't work as designed/intended.

But, it will work. Do you know the levels you need? Headroom may be a problem??? A qusi isolated system w/2 battreys system would solve most of the problems. And, if you built it hefty enough, can paower a PRW Amp too!

Maybe you could use a charge pump circuit.
