This family of single-output programmable ac-dc power supplies and wide-adjust output programmable ac-dc power supplies provide high power density, low ripple and a user-friendly front panel. These rack and benchtop units offer single output voltages ranging from 10 to 270 V with current capabilities to 120 A and wide-adjust voltages from 0-10 V to 0-270 V with current capabilities to 120 A. The power supplies accommodate an ac input voltage of 100-265 Vac, 49-420 Hz, single-phase with active power factor correction (PFC) of 0.99 single phase to ensure operation in challenging ac environments and compliance with European EMC requirements.
