The output of the +28 VDC Power Supply is adjusted depending on the type
of Quantum product it will supply power to, as indicated below:
When using the +28 VDC Power Supply Option to provide power for a Model
RS-580 Overhead Tube Crane, the +30 VDC output is intended for operating
the tube crane’s transverse and longitudinal electromagnetic locks (brakes).
Refer to the RS-580 Service Manual for connection instructions.
CAUTION! The Internal +28 VDC Power Supply
Option (QG-28VPS) is only available with 3-phase
generators, and is intended to supply power to a
single, external device.
