Astrodyne's GTMD family of single-output desktop-style power adapters, in 23 models, deliver 8W to 50W at 3.3V to 48V for class I and II medical and ITE (information technology equipment) applications.

These universal-input, ac-dc switching (100kHz) supplies feature an output (combined line/load) regulation of 5 percent, ripple and noise of 1 percent (typ) and operating efficiency of 80 percent (typ). Output connection is via a standard 2.1mm coaxial plug.

The supplies are protected against over-voltage and over-current. Input-to-output isolation is 4kVAC. They're rated for operation over 0 to 40C, derated linearly to 50 percent at 70C. Members of the GTMD series have CUL, VDE and TUV safety certifications and meet EN55022, 55011 and FCC Part 15 Level B EMI/RFI requirements.

The GTMD family, measuring as small as 3.4-by-1.85-by-1.26 inches, is priced from $33 each in OEM quantities. Delivery is 6 weeks ARO.
