The Powerbox OFI1200A Series OFI1200A28-N is a high-power, single-output AC/DC baseplate power supply designed for demanding industrial applications. Its conductive cooling design allows for effective heat transfer to the baseplate, making it suitable for non-ventilated or sealed enclosure applications.
This power supply operates with an input voltage range of 85-305VAC and provides a nominal output of 28VDC at up to 43A, delivering a total power of 1204W. Key electrical specifications include a power factor of 0.98/0.95, line and load regulation of 0.5% maximum, and a temperature coefficient of ±0.02%/°C. It supports paralleling of up to 9 units for increased capacity or redundancy.
The OFI1200A28-N is built for rugged environments, with features such as active current sharing, power good signal, remote sense, and remote on/off control. It meets vibration and shock standards according to MIL-STD-810H. The operating temperature range is -40°C to +95°C, with storage temperatures from -40°C to +85°C. Its mechanical dimensions are 142mm x 40.1mm x 260mm (W x H x D).
This power supply is suitable for various industrial applications and is compliant with standards such as 62368-1 and carries approvals from CB, CE, CSA, cURus, EN, UKCA, and UL.
