75W triple output AC-DC power supplies

April 09, 2015 // By Graham Prophet
TDK-Lambda’s CUT75 series of 75W PCB type, triple output AC-DC power supplies represents a 64% smaller design, that is lighter weight and more efficient (up to 85%) than the earlier generation JWT75 series.

Operating from a universal input of 85 to 265 VAC, the CUT75 is offered as two different standard models. The CUT75-522 model offers 5V and ±12V with independent converter, ensuring good regulation and no minimum load. By connecting the +12V and -12V output in series, this model can be used as a 5V, 24V dual output power supply. Similarly, the CUT75-5FF model offers +5V and ±15V and can be used as a dual 5V, 30V unit.

Convection cooled, the CUT75 series operates over -20 to +70°C. Standard features include over current protection and over voltage protection. Options include CUT75 models with cover (/A), baseplate (/B) and terminal block (/T). The series meets the conducted and radiated EMC requirements of EN55011/EN55022-B, FCC-B and VCCI-B, as well as IEC61000-4-2, -3, -4, -5, -6, -8, -11 immunity and safety approvals to EN/UL/CSA60950-1. It is also approved for medical applications by IEC60601-1 3rd Edition (2xMOOP) and designed to meet ANSI/AAMI ES60601-1. Delivered with TDK-Lambda’s 3-year warranty, the CUT75 series carries the CE mark, according to the RoHS and LV (low voltage) Directives.
