    The complete designation for a "stand-alone" controller housing a UPC- 32 is SCU/UPC-32. Such a unit can drive some of the larger PACIFIC AMX or ASX power sources through their rear panel interface. A typical usage might be to locate the power source at the base of an instrument rack, with the controller installed in an upper slot at a more convenient eye level or even in a completely different location.
