Behlman Electronics Inc. has introduced its DCR2U-2000D-6-28,71-12,33.3 critical mission COTS power supply, to meet the need for reliable dc output from a wide frequency of 3-phase ac aircraft power. Powered from 3-phase aircraft power, it provides up to 2,400 Watts of dc power to meet MIL-STD-704F input power requirements.
Behlman first announced in May, 2016, its plan to create the DCR2U Series of COTS power supplies to accept inputs of 200- to 375-Vdc; or 115/200 Vac, 3-phase at 360- to 440-Hz (IAW MIL-STD-704 and DO-160). To make this a truly versatile power supply series, custom inputs are also available upon request.
Output power of 2,000/3,000/4,000 Watts are available from the DCR2U series, with voltages from 3.3Vdc to 48Vdc. The new 2,400 Watt DCR2U-2000D Power Supply is specially designed to provide +28Vdc at 71A (2000 W), and +12Vdc at 33.3A (400 W). Like other DCR2U power supplies, this unit also has protective circuits, controls, and indicators, and wide-ranging operating and storage temperatures. It is also designed to meet MIL-STD-810F for Shock and Vibration, and MIL-STD-461E for EMI/EMC (RE102 inside external enclosure.
Behlman DCR2U Critical Mission COTS Power Supplies are designed to be mounted in 19†racks, and need only 2U (3.50â€) space. Weight is 28.9 pounds.
Making the announcement from the company’s New York headquarters, where the DCR2U is designed and manufactured, Behlman president, Ron Storm, said, “We are excited to see the incredible work of our engineering team as they continue to build upon the COTS DCR2U power platform, to meet so many specific DC power needs for current and emerging aircraft. With the DCR2U series, we have laid a foundation for customized power solutions without the high cost of full custom R&D. I invite you to watch for announcements of our new “Critical Mission COTS power solutions as they are released, or tell us what you need for maximum performance and reliability of your airborne, shipboard, mobile or industrial programs.â€
