The Powerbox OFM2255226 is a versatile 165W AC/DC switch mode power supply designed for ITE (Commercial) and Medical applications. It operates with a universal input voltage range of 90-264 VAC and provides a fixed 15V output.
This open frame power supply features a standard 3x5 inch footprint with a chassis mount design, making it suitable for integration into various systems. Key electrical specifications include a high efficiency of up to 92%, line and load regulation of ±1%, and overcurrent protection up to 130% of the rated current.
The OFM2255226 is approved according to CE and UL standards, including IEC/UL 60601-1 and IEC 60950-1, ensuring compliance for medical and commercial equipment. It offers superior EMC performance and intelligent over-temperature protection for reliable operation. The unit also supports parallel operation for higher output power requirements and has a low zero-load power consumption of approximately 0.3 Watts.
Environmental considerations include an operating temperature range of 0°C to 50°C at full load, with derating to 50% power at 70°C. It also meets Green Mode requirements for energy efficiency.
