The family consists of the CUS30M, CUS60M, CUS150M, CUS200M, and CUS350M supplies, with options for convection cooling for silent operation with loads up to 350 W or forced air cooling for up to 420 W. The supplies can operate from -20°C to +70°C, with the CUS150M offering an extended operating temperature of up to +85°C. The supplies are compact, ranging from 2” x 3” for 30 W and 60 W supplies to 3.4” x 7.5” for 350 W. CUS-M supplies are suitable for Class I and Class II installation, and models are suitable for B and BF rated equipment.

TDK-Lambda designed the CUS-M supplies to provide exceptional performance. The family provides conversion efficiency up to 94%, with less than 0.5 W of standby power consumption. The supplies are offered with a single output at popular voltages from 5 V to 48 V, and this output is adjustable by up to 10% to tune to the application’s specific voltage requirements. The supplies also keep leakage current to a minimum at under 0.3 mA.

CUS-M power supplies are certified to IEC60601-1 and IEC60950-1 for use in medical and ITE applications, and they meet Class B limits for conducted and radiated emissions. The supplies meet the requirements for 2x MOPP between input and output and 1x MOPP for input-to-ground and output-to-ground.
