Medical power supply range expanded
1 min read
TDK Lambda has announced the addition of three new models to its range of digitally controlled medical power supplies, which it claims can help boost efficiency to 90%.
The models, which have nominal outputs of 28V/10.71A, 40V/7.5A or 48V/6.26A, are the latest additions to the power solution specialist's EFE300M range.
According to TDK Lambda, the new units deliver 300W continuous power (400W peak for 10 seconds) and can accommodate non standard system voltages by factory programming. The 8bit microcontroller has been designed to provide full digital control of the output and typical densities of up to 16.6W/in3 are said to be achieved under peak load conditions and 12.5W/in3 under continuous loading.
A 12V/1A fan supply is included and models operate from 90-264Vac input with dual fusing, and TDK Lambda describes the earth leakage current as 'better than 300µA' which complies with medical safety requirements, while the active power factor correction is said to ensure EN61000-3-2 compliance.
The use of digital control means that the EFE300M is small and with features such as redundant operation capability and a high current standby output, the supplies are suitable for high integrity applications such as broadcast, instrumentation, routers, servers and security networks.
