TDK-Lambda Americas has extended the power range of their digitally-controlled EFE-M series of medical/ITE power supplies from 300W to 400W. The EFE400M series designed for Medical and ITE applications offers a 4kVAC reinforced input to output isolation and an output-to-ground isolation of 1500VAC.
The EFE400M meets the international safety standards of IEC/UL 60601-1 for medical equipment, making it suitable for use in B (body) and BF (body floating) type medical and dental applications. Regulated DC outputs of 12V, 24V, or 48VDC are standard, plus other voltages can be provided.
The EFE400M series includes an integrated magnetics transformer (transformer and inductor windings on the same core) to boost efficiency to typically 90%. It employs an 8-bit microcontroller for full digital control of the output and to handle housekeeping routines. This results 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 15.6W/in3 are achieved under peak load conditions and 13.1W/in3 under continuous loading.
The EFE400M delivers 400W continuous power and up to 475W peak for 10 seconds. Non-standard output voltages can be accommodated via factory programming. An additional 12V/1A fan output is included and all models operate from a universal 90 to 264VAC input with dual-input fusing as standard.
With a 3.5 x 6.5 inch footprint and less than a 1U profile (1.34" to1.60") the EFE400M can be incorporated into designs where space is limited so the end product can be smaller and cooler. Other features include a redundant operation capability, a standby voltage output and ITE safety certifications per IEC/UL 60950-1.
The EFE400M series pricing starts at (US)$224.00
