CUI Inc. — DC/DC Converters Ideal for Renewable Energy Applications


cui-inc NPI_LOGO
The AE series, available in board mount, chassis mount, and DIN rail mount configurations, offers power ratings of 5W, 10W, 15W and 40W with input voltages up to 1500Vdc and input ratio ranges up to 10:1.

Designed for reliable operation in renewable energy applications such as solar power equipment, wind turbines, and electric charging stations, the new models feature 4000 Vac input to output isolation and a wide operating temperature range of -40°C up to +70°C at full load. The series is also rated to operate at up to 5000 meters, allowing it to support remote, high altitude installations.

These new isolated DC/DC converters are housed in fully encapsulated packages for use in harsh environments with measurements beginning at 2.75 x 1.89 x 0.93 inches (70 x 48 x 23.50mm). Output voltage options of 5, 9, 12, 15, and 24Vdc are available, depending on the series, including efficiency ratings up to 84%. Standard is the protection for over-voltage and overcurrent, as well as continuous short circuit with automatic recovery.

The AE series further carries EN 62109 safety approvals and is rated to meet CISPR22/EN55022 Class A limits for conducted and radiated emissions, while the AE-UW series holds an additional UL 1741 safety approval.
