High efficiency DC-DC converter designed for industrial 12VDC and 24VDC systems

The third modular DC-DC converter development from Murata Power Solutions is designed for industrial 12VDC and 24VDC systems. The ICF series follows the same design principles to provide an industrial grade, rugged, high-power, baseplate-cooled DC-DC converter. Capable of delivering up to 1,000W from an input source of 9VDC to 36VDC with a typical efficiency rating of 96.4%, the ICF series offers two output voltage options (24VDC or 28VDC) and is packaged in an enclosed industry-standard full-brick package. Measuring 119mm x 64mm x 13.2mm, the converter is enclosed in a specially designed package/baseplate that meets the environmental stress limits for shock and vibration specified in MIL-STD-810G, while offering full power with a baseplate operating temperature range of -40C to 105C without derating. The series achieves its high performance by incorporating proprietary circuit architectures, advanced packaging, and thermal design advances. Accommodating an input voltage range of 9VDC to 36VDC, two single output models are available, providing a nominal 24VDC or 28VDC regulated output. The outputs are fully isolated from the input supply, allowing flexibility for various grounding requirements or for creating positive or negative outputs. A Basic insulation system provides galvanic input-to-output isolation rated at 2250VDC that is provided across all models. The series has been designed to meet EN60950, UL/CSA safety requirements for embedded power modules. The industry-standard full-brick enclosed package has been specially designed to meet the demands of rugged operating environments and complies with the MIL-STD-810G standard for functional shock and vibration. Typical applications include 12VDC or 24VDC battery systems, powering motor drive systems, emergency vehicle electronics, smart grid, and heavy-duty truck power bus solutions. The ICF series has no minimum load requirement, keeping energy consumption to a minimum when the end device is in standby as well as ensuring stable operation in low load conditions. All modules come with a positive logic remote On/Off control as the standard configuration, along with full protection features including input transient to 50VDC, over-temperature shutdown, output over current and input under-voltage lockout.
