No Min Load for Medical 2” x 4” 35W Triple-Output AC-DCs
TDK Corporation announced the introduction of TDK-Lambda's CUT35 low-profile, triple-output power supplies. Packaged in the industry standard 2" x 4" footprint, the CUT35 requires no minimum load, simplifying installation. The easy to use power supplies are designed for medical, industrial, broadcast and test & measurement applications.
Operating from a universal input voltage of 85- to 265-Vac, the CUT35 is available in two standard models. The CUT35-522 offers 5V +12V output voltages and the CUT35-5FF 5V +15V with an output power of 35W. The units can be configured as dual output power supplies (5V / 24V or 5V / 30V) by connecting outputs 2 and 3 in series.
The two converter topology of the CUT35 enables zero minimum load operation, good regulation and provides 500Vac isolation between the 5V and the secondary outputs. The 5V output is user adjustable from 5V to 5.25V, and does not impact the secondary output voltage settings. Convection cooled, the series features a wide operating temperature range from -20 to +70 degrees C ambient (with appropriate de-rating above 60 degrees C) and carries a 3-year warranty. Options for the product series include a cover (/A) and a mounting baseplate (/B).
The CUT35 series has been certified to IEC/EN/ES 60601-1, IEC/EN/UL 60950-1 and carries the CE mark according to the LV and RoHS2 Directives. Input to output isolation is 3,000Vac, input to ground 2,000Vac and output to ground 500Vac. Leakage current is less than 300µA. All models meet EN 55011-B, FCC Class B conducted / radiated emissions and IEC 61000-4 immunity standards.
