With a typical efficiency of 92.5%, the fully isolated PAE series delivers 100W in a standard open frame eighth-brick package; the through-hole mounted converter is available with an optional baseplate for conduction cooled / cold wall applications typically found in base-station applications and remote radio heads. The converter operates over the industry standard TNV input voltage range of + 36 to +75 VDC around a nominal +48 VDC. The single +29.8 Vout can be adjusted over a wide range, from +23.84 to 32.78 VDC.

Controls include remote On/Off control of either negative or positive logic. In addition, the converter has a number of protection features including over current, over temperature, input under voltage and output short circuit. The PAE converter is designed to operate in environments ranging from – 40 to + 100C. Input to output isolation is 1,500 VDC with a Basic insulation system to meet industry safety requirements. An optional baseplate is offered with an available “baseplate connect pin” that can be connected to system ground, providing additional flexibility for power system design engineers. The PAE series has been designed to meet the demanding “low noise” requirements in modern communications systems and will require minimal Vout filtering in most applications.
