These power supplies offer high power densityin plug-in modules that meet the requirements of the PICMG® power interface specification for CompactPCI®systems.The converters use the patented EDGETM technology and provide important advantages such as flexible outputpower, extremely high efficiency, excellent reliability, full input-to-output isolation, negligible inrush current, hot-swapcapability, soft start, and overtemperature protection.The input is protected by a transient suppressor (varistor) against surges and transients occurring on the source linesand cover an operating input voltage range from either 90 to 264 VAC or 36 to 75 VDC.The outputs are protected against continuous overload, open-circuit, and short-circuit. Full n 1 redundant operatingmode is made possible by integrated ORing FETs or ORing diodes. When several converters are connected in parallel,a single-wire connection between converters ensures current sharing.The converters are designed as two or three separate forward converters with fixed switching frequency and synchronous rectifiers at their output.LEDs on the front panel and various warning signals display the status of the converter. The aluminum case acts as aheat sink and as an RFI shield. It is designed for vertical insertion into 19″ rack systems, but it can also be mountedin any other position, as long as the necessary airflow is ensured. The connector is a 47-pin type from Positronic orsimilar.Several options are available to meet different requirements.
