TDK Corporation announces the introduction of the 250W rated TDK-Lambda brand 2”x4” footprint CUS250M series of AC-DC power supplies. The series is certified to both IEC 60601-1 and IEC 62368-1 standards for both Class I and Class II (double insulated) installations. Target applications include medical, home healthcare, dental, test and measurement, broadcast, professional audio and industrial equipment.
Conduction and convection cooling enables silent operation, and the CUS250M can deliver up to 250W in -20°C to +50°C ambient temperatures. Operation at +80°C is also possible with appropriate derating. With 1m/s forced air cooling utilising system airflow or the optional integral fan, the U channel models can deliver 250W in a +50°C ambient, derating to 125W at +70°C. Options for the CUS250M include a 5V 0.1A standby voltage, remote on/off, DC OK and AC Fail signals and a choice of U channel, U channel with cover or top mounted fan mechanical construction.
12V and 24V models will be available initially, with 15V, 18V, 28V, 36V and 48V outputs following later.
With efficiencies up to 94%, less internal heat is generated allowing reliable operation.
