ZMS100 Series Power Supplies

TDK-Lambda's ZMS100 single-output power supply conforms to the new IEC60601-1 3rd edition medical standard with input to output isolation of 4 kVac and 2 x MOPP (means of patient protection) with a compact 2 x 4 inch footprint and less than 100 µA touch current. The ZMS100 is suitable for both class I and class II (or double insulated) applications meeting the safety requirements for hospital, clinical, dental and home-based medical environments.

In addition to medical applications, these high performance supplies are equally well-suited to broadcast and professional audio applications. They can be convection-cooled at outputs of 80 W and below, so no fan is required and therefore no audible noise is present. Other applications include test and measurement equipment, and LED displays and signage.

The ZMS100 range covers all commonly used output voltages from 12 V to 48 V with 90% typical efficiency, and meets ErP guidelines with less than 0.5 W no load power consumption and an average active efficiency of greater than 87%. To accommodate non-standard system voltages, the ZMS100 is user adjustable by -5%/+10%. Operating from a universal input, the ZMS100 power supply can deliver up to 80 W at 50°C under convection cooling and 100 W at 50°C in forced air (only requiring a low airflow of 0.37 m/s at 230 Vac input).
