It depends upon the built in power supply ! The old version A-100TN12 had
only 650mA (manufactured until about 2001), the new version A-100PSU2 has
1200 mA.
The label at the power supply inlet should tell you the type of supply. If
there is no label it's probably the old version wit 650 mA only. To be on
the safe side you have to look at the power supply. It there is a black
ashlar-formed block it's the A-100NT12 with 650mA. If there is a ring-core
transformer it's the new A-100PSU2 with 1200mA
