Triple-output supplies provide flexible power

Two new triple-output AC/DC power supplies are ideal for 1U "pizza-box" applications and can provide enhanced flexibility in the physical layout and power distribution architecture of the host system.

Power-One has expanded its BLP55 Series by adding the BLP55-3000 and the BLP55-3300 triple-output AC/DC power supplies.

These products are ideal for 1U "pizza-box" applications as they are very cost effective and can provide enhanced flexibility in the physical layout and power distribution architecture of the host system.

Host-system physical-layout flexibility is enhanced by reduced airflow requirements (eliminating the need to be directly adjacent to a cooling fan) and a low 1.25in height that reduces airflow shadowing to improve cooling of downstream devices.

Power-distribution architecture flexibility is enhanced by the availability of 3.3 and 5V outputs, suitable for any desired combination of bus voltage and/or direct-power usage.

Both models accept a wide-range 85 to 264V AC input, and only need a linear airflow of 3m/min to provide full-rated power.

The BLP55-3000 delivers +5V at 5A, +12V at 2.5A and -12V at 0.7A.

The BLP55-3300 provides +3.3V at 5A, +5V at 2.5A and +12V at 0.7A.

Additional features include a compact 3.00 x 5.00 x 1.25in (76.2 x 127.0 x 31.8mm) package that is compatible with industry-standard footprints and connectors, remote sense, and output overvoltage protection.

Regulatory agency approvals include UL recognition to UL60950-1/CSA 22.2 No 60950-1 and TUV approval to EN60950-1.

Onboard EMI filtering provides Class B compliance to FCC CFR Title 47, Part 15, sub-Part B - Conducted; and EN55022/CISPR 22 Conducted Class B.

The BLP55 triple-output models are competitively priced at $30 each for 100-piece quantities.

Evaluation units are available from stock.

Production quantities are typically available in less than 12 weeks.
