TDK Corporation is introducing a 700W model to the TDK-Lambda PFE-SA series of AC-DC full-brick power modules. A significant upgrade to the popular PFE700S launched 5 years ago, the PFE700SA comes with a 3 per cent efficiency improvement, providing a convenient AC-DC board mounted product for applications such as industrial, MIL-COTS, broadcast, datacom and telecom, test & measurement, LED displays and signage. Being a baseplate-cooled product, the PFE700SA is particularly well suited for building into outdoor applications, as well as equipment requiring water-cooling, hermetic sealing, fanless operation and compact design.

Available in a 51V semi-regulated output, the PFE700SA can deliver full power with a baseplate temperature of between -40 and +100degC. Line and load regulation is 50 to 57V and typical efficiency for the PFE700SA is up to 91 per cent.

As with all models in the PFE-SA series, which includes the 300W PFE300SA and 500W PFE500SA, the PFE700SA accepts a wide, universal AC input from 85V to 265V at 47–63Hz and features active power factor correction and an input to output isolation of 3kV for 1 minute. The inverter operation good functions provide flexibility in the diagnostics of the power system. In addition, over voltage, over current and over temperature protections are included.

Coming with a 5-year warranty, the PFE700SA conforms to EN/UL/CSA 60950-1 safety approvals for general purpose applications and carries the CE mark according to the low voltage (LV) and RoHS Directives.
