What are the key features of the CUS100ME series of 100W AC-DC power supplies?
The CUS100ME is a single output 2″ x 4″ AC-DC power supply with IEC 60601-1 3rd edition medical approval and IEC 62368-1 approval for ICT/AV applications. It is suitable for Class I installations and Class II installations without a protective earth.
The CUS100ME is available in four mechanical formats – open PCB, PCB with baseplate, with U-channel, and with U-channel and cover. The baseplate and U-channel versions provide additional cooling assistance via heat conduction. Gap pads are used to conduct heat away from the underside components and into the baseplate and equipment chassis.
The power supply is rated at 100W maximum output power, which can be achieved with convection cooling at ambient temperatures of up to 50°C for the PCB version and up to 60°C for the U-channel version. With baseplate and U-channel conduction cooling assistance, this rating can be achieved at up to 70°C ambient. With forced air cooling at 1m/s, operation at up to 85°C ambient temperature is possible.
The CUS100ME is highly efficient at up to 94% and has a low standby power consumption of less than 0.5W. The standard available output voltages are 12V, 15V, 18V, 24V, 28V, 36V, and 48V. Non-standard voltages at up to 10% above these nominal values can be supplied on request.
Our design priorities for these compact power supplies include cost optimisation along with excellent thermal design and performance. Particular attention was paid to the electrolytic capacitor temperatures so that above average field life would be achieved.
The CUS100ME meets Class B levels for both conducted and radiated EMI, and it comes with a 5-year warranty.
