POWER SUPPLY UNIT
TYPE AD100-015
The AD100-015 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 1A of current at +15V DC potential and is used as a substitute for
battery power with mixers containing an internal DC-DC converter.
The AD100-015 may be powered from either a 110/120V AC source or a 220V/240V
AC source. Ensure that the AC voltage source is in the range 100V to 240V AC.
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 PSU
contains an indicator that illuminates when the PSU is operational.
FOR SAFETY REASONS, AD100-015 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 AD250 series mixer, they may
be recharged in situ from an AD100-016 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 charge circuit within the mixer is powered by
connecting to Pin 2 of the 4 pin DC Power XLR. DO NOT ACTIVATE THE CHARGE
CIRCUIT UNLESS THE MIXER IS FITTED WITH NICKEL-CADMIUM CELLS.
REMOVE CHARGE LINK FROM POWER-IN XLR IF DRY-CELLS ARE FITTED.
FUSE: A fuse link should be fitted to the mains supply to protect against fault
conditions
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.
