Subject: Diskless Node power supplies


I have looked at the following power supply manufactures in hopes of finding a 
supply for the Diskless Node. Power General and Todd appear to be the only
manufactures of supplies that will closely suit our electromechanical
requirements. The other manufacturers build supplies which have inadequate
electrical output for our mechanical needs. The supplies which meet our
electrical needs are typically 12 to 15 inches in length.

ACDC Electronics
Boschert
California DC
Calex

Conver
Deltron
Digi-Power

GFC Hammond
KEC

Ulveco
Xentek

Power General responded to our requirement and said they would have to redesign
their supply and re-layout their PC board. Jeff Kelly of Power General said
he would talk to their engineering group and come up with new pricing (and
the NRE charge). I expect this figure to be between $8000.00 and $15,000.00.
This is based on a quote I received from Conver.
