Astrodyne Corp. announces its ASL150 series of high density, open frame switching power supplies that meet the space and performance requirements for instrumentation, control and telecommunication systems. Delivering 150W of output power, these compact units exhibit power densities greater than 17W/in3. A 1.08¨ profile makes them appropriate for 1U applications. All models accept universal input from 90V AC to 264V AC, and four models are available that provide single outputs of 5V DC to 48V DC. The modules occupy a mechanical footprint measuring 2¨ × 4¨ × 1.08¨. All models contain over-voltage, over-current and short circuit protection circuitry, and they feature Molex-style I/O connectors. The series is fully approved to CSA/NTRL, NEMKO safety specifications. Medically approved non-commercial versions are also available.
