Applications that previously required a half brick AC front end module and a full brick DC-DC converter are now satisfied by the PFE module which is one of the smallest and most powerful of its kind on the market.
Offering space savings of up to 50% compared with previous solutions, the innovative new PFE-series AC-input ‘full brick style’ power supply modules ( the product line is so innovative it currently has seven patents pending) are capable of delivering up to 700W whilst operating at up to 100ºC base plate temperature. This greatly simplifies cooling requirements even when the modules are used in demanding environmental conditions. Meeting the needs of many industrial, data communications and telecommunications applications, particularly where high operating temperatures are involved, the new PFE modules provide designers with power factor correction, regulation and isolation in a single convenient and compact package. The PFE300, 300-watt PFE power supplies are available with fully regulated 12V, 28V and 48V DC nominal outputs, that can be adjusted by ±20% to allow an exact match with the customer application requirement. The fully regulated PFE 500-watt models are available with 12V, 28V and 48V nominal outputs that can be adjusted over a range of ± 20%. The 12V PFE500 delivers 396W with a maximum base plate temperature of 85ºC, while the 28V and 48V models provide 504W at 100ºC base plate temperature. Line and load regulation is 0.4%.
The semi-regulated PFE700-48 can deliver 714W with a nominal output of 51V, making it ideal for use as an intermediate bus converter to power regulated DC-DC converters in multiple-output applications. Maximum base plate temperature for the PFE700-48 is 100ºC, with the output derating linearly above 85ºC to 85% load. Line and load regulation for this model is 4V.
PFE-series power supply modules accept a wide range AC input from 85V to 265V. As standard, they incorporate active power factor correction and input-to-output isolation of 3000V AC. Over-voltage, over-current and over-temperature protection are included. The modules measure just 117 x 61 x 13mm, and can be cooled with a cold-plate or an optional heatsink. When correctly installed (Amtex offers local engineering design & support), the PFE-series modules meet Class B EMI standards (radiated and conducted), and are safety approved to UL60950-1 and EN60950-1. All units are RoHS compliant, and all carry the CE mark.
