utput for use with
adjustable speed DC and AC drives. Used in all tension
zones; unwind, rewind and intermediate.
- 0-90 Vdc output. For use with all types of electrical
brakes and clutches, including eddy current clutches.
Also available with 24 and 45 Vdc output. Commonly
used in the unwind or rewind zones.
- 0-75 psi output for use with pneumatic clutches and
brakes. Most commonly used in the unwind and rewind
zones.
