Lead acid batteries are close to 2V per cell. For cars/trucks, they come
conviently packaged in 6V and 12V units. The phone company works off 48V.
But where does 28V come from?
The Isotemp OSCO 127-10 data sheet says 27 V, but that's +3, -6 or 21-30V
which straddles both 24V and 28V.
These are my opinions, not necessarily my employer's. I hate spam.
