CUI Inc has announced the addition of a 2000 W front-end ac-dc power supply to its power supply portfolio. The PFR-2100 series is a blind-mate rectifier with a programmable output voltage range of 100~410 Vdc. Key features include a hot‑swap blind-docking capability implemented through the use of a single connector that integrates ac, dc and I/O signals. The PFR-2100 delivers high efficiency up to 93% in a package measuring 11.5 x 5.2 x 2.5 inches (292.1 x 132.08 x 63.5 mm). The series is ideally suited for use in data center high voltage dc bus power systems, broadcast amplifiers, and EV battery charging systems.
The programmable dc output voltage delivers a constant current up to 5.125 A with droop current sharing for paralleling up to 12 units. Additional features include power factor correction, remote on/off control, power good signal and front panel LED indicators. The PFR‑2100 series complies with all applicable EMC requirements to accommodate worldwide applications and offers 60950-1 safety approvals. Protections for over-voltage, over-current and over-temperature are also provided.
