With a 4 kVAC I/O isolation and an output-to-ground isolation of 1,500 VAC, digitally controlled 300-W power supplies from TDK-Lambda meet the IEC 60601-1 for medical equipment. Regulated DC outputs of 12 V or 24 VDC are standard, and features include an integrated transformer and 8-bit microcontroller. The supply delivers 300 W continuous power (400 W peak for 10 seconds) with nominal outputs of 12 V at 25 A or 24 V at 12.5 A. Leakage current is less than 300 µA at up to 264 VAC.
