A6 AFU-APS-I/O: Auxiliary Power Supply (APS)
A6.1 Description
The Auxiliary Power Supply (APS) side of the AFU-APS-I/O contains a 24 V
dc Power Unit for the AFU and/or Transceiver. It requires an ac mains input
in the range 90 to 132 or 187 to 260 V ac, 50 to 60 Hz. The supply voltage
range is selected automatically.
It also contains circuit breakers and terminals for supplying ac power to two
blowers.
For specifications, see Section D.
The APS can be supplied as an integrated unit with an AFU, or as a standalone
unit.
The standalone units can supply power to the AFU (and thus the 4500 MkIII)
or to the 4500 MkIII directly.
CAUTION
Only Land-supplied blowers may be connected safely to the APS.
The connection of any other equipment to the shutter/blower
terminals may be hazardous.
Approved blowers are listed in the table below:
Part Nº Description
099.471 Plate-Mounted Blower (230 V, 50 Hz)
099.472 Plate-Mounted Blower (220 V, 60 Hz)
099.473 Plate-Mounted Blower (110 V, 60 Hz)
803550 Blower Small, USA (220 V, 60 Hz)
803551 Blower Small, USA (110 V, 60 Hz)
806441 LC Economy Blower (110 V, 60 Hz)
806440 LC Economy Blower (230 V, 50 Hz)
CAUTION
Incorrect supply voltage/frequency can cause the motor to burn
out, compromise performance or cause an explosion.
The connection of a blower restricts the allowable voltage range of
the APS to that of the shutter/blower.
The blower supply voltage/frequency are detailed on the rating
plate of the supplied motor. Check carefully.
Do not exceed the rated supply values. External wiring must be
rated to >70°C / 158°F if the ambient temperature can rise above
50°C / 122°F.
