TDK-Lambda has introduced its ZM series of sub-300W power supplies, starting with the ZMS100, which has been designed and developed in the UK.
The ZMS100 single-output power supply conforms to the new IEC60601-1 3rd edition medical standard. Its features include input-to-output isolation of 4kVac and 2xMOPP (patient protection standards).
Both input to ground and output to ground isolation levels are 1.5kVac 1 x MOPP. The ZMS100 has a compact 2x4 inch footprint and uses less than 100µA touch current, making it 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.
These supplies are also well suited to broadcast and professional audio applications. They can be convection-cooled at outputs of 80W and below, enabling quiet fan-free operation. Other applications include test & measurement equipment, LED displays and signage.
The ZMS100 range covers standard output voltages from 12 to 48V with 90% typical efficiency, meeting ErP guidelines with less than 0.5W power consumption under no load and an average efficiency of greater than 87% when under load.
It can also accommodate non-standard system voltages through user adjustment in the range -5% to +10%.
When operated from a universal input, the ZMS100 power supply can deliver up to 80W at 50°C under convection cooling and 100W at 50°C in forced air (only requiring a low airflow of 0.37m/s at 230Vac input).
