Archive lists the power requirements for the 2060S and 2150S
(in their June 1988 revision product manual) as:

                              +12V             +5

 Tolerance (incl. max.       +-10%            +-5%
 ripple of 200mV)

 Standby Current          0.2 amps nom.   0.45 amps nom.

 Operational Current      0.8 amps nom.    0.5 amps nom.
                          1.5 amps max.    0.7 amps max.
 
 Tape Start Surge         2.5 amps max.
 (up to 300msec.)

 Power Dissapation        20 watts typ.
 (operational)            35 watts max.

I think you should look for another enclosure.  BTW, I've had no
trouble with a 2150S mounted inside my standard desktop enclosure.
