[sdiy] SEM: power supplies?

[Jeffrey Pontius]

I am supposed to be receiving an SEM front panel/pcb soon and need to
purchase a power supply.  From reading about the SEM it requires a +-18.5V
linear power supply.

(1) A message in the AH archives indicated that the max. amperage of one
SEM is about 75 mAmps.  Can anyone verify or refute this?

(2) Any suggestions for a suitable power supply?  For example, the Power
One HAA24-0.6-A seems appropriate, but may be a bit of overkill
amperage-wise.

Thanks, Jeff
