Open-frame stepper drives require a
separate DC power supply for operation.
Omegamation offers two power supplies that
are matched for use with our open-frame
stepper drive selection: the OMPS150A24
and the OMPS300A48.

Both power supplies are switched-mode,
regulated DC power supplies with active PFC
filters. The OMPS150A24 is 24 Vdc, 6.3 A
(150 W)

while the OMPS300A48 is 48 Vdc,

6.7 A (300 W).
