KB Electronics KBWS-25D - Manual (Page 7)

The KBWS contains built-in isolation for all signal inputs. This includes input signal
voltage, Main Speed Potentiometer terminals, Inhibit Circuit and +5VDC power sup-
ply. The dual voltage models contain a jumper to select motor voltage and special
circuitry which automatically accepts AC Line input voltages of 115 or 208/230 Volts
AC without having to make a jumper selection. See Application Note, Section VII,
on page 18.
Optional accessories for the KBWS include a DIN Rail Mounting Kit, a Product
Safety Module (PSM) and an AC Line Fuse Kit. See Section XI, on page 23.
