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 PS150A24 and the PS300A48.
Both power supplies are switched-mode, regulated DC power supplies with active PFC filters. The PS150A24 is 24 Vdc, 6.3 A (150 W) while the PS300A48 is 48 Vdc, 6.7 A (300 W).
