Front-End Supplies Take Digital Control Up A Notch

The EFE Series embedded front-end power supplies rely on an eight-bit MCU for full digital control of the output and to handle housekeeping routines Reportedly, this reduces part counts by 25% and achieves a 45% smaller and 56% lighter design than comparable units. The 300W EFE-300 and the 400W EFE-400 single-output supplies deliver a 133% peak power capability for 10s and efficiencies up to 90%. With 1U profiles, the EFE-300 measures 3” x 5” x 1.34” and EFE-400 logs in at 3” x 6” x 1.34”. The EFE-300 delivers 300W continuous power and 400W peak for 10s with nominal outputs of 12V/25A or 24V/12.5A. The EFE-400 outputs 400W continuous and 530W peak for 10s with nominal outputs of 12V/33.3A or 24V/16.7A. Available now, prices start at $150 each/500. TDK-LAMBDA, San Diego, CA. (800) 526-2324.
