POWER SUPPLY UNIT
TYPE AD100-09
The AD100-09 mains POWER SUPPLY UNIT is suitable for driving most of
AUDIO DEVELOPMENTS’ range of portable audio mixers.
This PSU is a single-rail
device providing 500mA of current at +14v DC potential and is used as a substitute for
battery power with mixers containing an internal DC-DC converter.
The AD100-09 may be powered from either a 110/120v AC source or a 220v/240v AC
source.
Ensure that the AC Voltage Selector Switch on the front panel is in the
correct position for the source in use. Operating the equipment at the wrong voltage
could be hazardous.
Care must be taken to connect the LIVE, NEUTRAL and
EARTH pins of the PSU’s IEC mains connector to the corresponding terminals
associated with the AC source. The ON/OFF switch contains an indicator that
illuminates when the PSU is operational.
FOR SAFETY REASONS, AD100-09 POWER SUPPLY UNIT MUST BE
CONNECTED TO MAINS EARTH. Any maintenance to the PSU or its mains cable
assembly should be performed by a qualified engineer.
CHARGING: If nickel-cadmium cells are fitted in an AD140 series mixer, they may
be recharged in situ from AD100-09 power supply - whether the mixer is in use or not.
(Maximum current is set at 250mA - in addition to the 500mA of current supplying the
audio electronics.)
The charging circuit has its own ON/OFF slide switch and LED
indicator. DO NOT ACTIVATE THE CHARGE CIRCUIT UNLESS THE MIXER IS
FITTED WITH NICKEL-CADMIUM CELLS.
FUSES: Two 20mm ANTI-SURGE fuses protect AD100-09 against fault conditions.
Should either fail, it is strongly recommended that the cause be traced. Refer to the
TECHNICAL LIBRARY. Only suitably qualified personnel should service the power
supply unit. The fuse holder on the front panel contains the mains fuse.
For continued safety the specified fuse link must be fitted in the mains fuse holder
when a replacement is required.
Ensure it is of a type approved by a National
Approved Body.

NOTE: The power supply unit should be serviced by a suitably qualified engineer.
Only genuine spare parts with identical specification must be used.
It is DANGEROUS to change the specification or modify the product in any way.
