With a 3.5 x 6.5 inch footprint and less than a 1 U profile, the EFE400M can be incorporated easily into designs where space is limited so the end product can be smaller and cooler. Other features, such as a redundant operation capability, a standby voltage output, and ITE safety certifications per IEC/UL 60950-1, make the EFE400M equally suitable for high-integrity applications (in addition to medical).
The EFE400M series includes an integrated magnetics transformer (transformer and inductor windings on the same core) to boost efficiency to typically 90% and employs an 8-bit microcontroller for full digital control of the output and to handle housekeeping routines. This resulted in a 25% parts count reduction to achieve a 45% smaller and up to 56% lighter design when compared to similar competitive products. Power densities of up to 15.6 W/in3 are achieved under peak load conditions and 13.1 W/in3 under continuous loading.
