my favorite replacement power supply would be the:
Astec P/N MP6-3E-1L-1L-00
5VDC 120 amp 600 Watt ( 3E in the part number)
12VDC 17 amp 210 Watt ( 1L in the part number)
12VDC 17 amp 210 Watt (1L in the part number)
this is the "raw" repalacement that Charmilles uses for the Weir.
Charmilles mounts it on a plate and adds a terminal strip, gives it a part number and sells it
for twice the price of the astec.
