Sixteenth-brick provides 12 V at 7 A

11 November 2009 Power Electronics / Power Management

Power-One has introduced the SSQE48T07120 DC-DC converter, an ideal DPA or IBA power source for communications, data server/storage, and workstation applications with efficiencies up to 93%.

This DOSA-compliant sixteenth-brick provides 12 V d.c. at 7 A with 100% of full-rated power available at 55°C, and 7 A at 70°C using 200 LFM airflow.

The product also features the capability to withstand a 100 V input transient for 100 ms, meets EN 60950 basic insulation requirements, and is UL94 V-0 flammability rated. Additional features include a wide-range 36 to 75 V d.c. input, the capability to start up into pre-biased loads, and no minimum-load operation.

Protections include hiccup mode over-current, output over-voltage, input under-voltage lockout, and over-temperature shutdown. Interface and trim capabilities include remote sense, remote ON/OFF (positive or negative logic option), and +10%/-20% output voltage trim ranges with industry-standard trim equations. Approvals include UL/CSA 60950-1, EN 60950-1 and IEC EN 60950-1. A low 9,5 mm profile reduces airflow shadowing, facilitating improved cooling for downstream components. The SSQE48T07120 features a DOSA-compliant through-hole-mount pinout and 22,9 mm x 33 mm footprint.
