CUI INC – New line of DC-DC converters offer reliable performance in renewable energy applications


CUI’s Power Group has announced a new line of DC-DC converter modules, the AE series, which provides for reliable operation in renewable energy applications.

Available in board-mount, chassis-mount and DIN rail-mount configurations, the AE series offers power ratings of 5W, 10W, 15W and 40W. Devices in the series support a range of input voltages up to 1,500V DC, and input-ratio ranges up to 10:1.

The new AE models offer 4,000V AC input-to-output isolation. The devices can operate at altitudes up to 5,000m, making them suitable for use in remote installations.

These isolated modules are housed in fully encapsulated packages, the smallest of which measures 70mm x 48mm x 23.5mm.

The AE series has EN62109 safety approvals and conforms to the CISPR22/EN55022 Class A specifications for conducted and radiated emissions. The AE-UW series holds an additional UL 1741 safety approval.
