Medical power supplies conform to BF type medical applications
TDK-Lambda has launched the NVM175 range of medically approved AC-DC power supplies. Combining 4.5kVac reinforced input to output isolation with dual fusing and an output-to-ground isolation of 1500Vac, the NVM175 meets UL/EN/IEC60601-1 and is suitable for use in BF type medical applications.
Offered in a 5 x 3in footprint with less than 1U height, the new NVM175 supplies have universal ac input and are rated at 180W at 50°C with customer air. According to TDK, leakage current is less than 200µA at 264Vac/63Hz surpassing worldwide medical equipment requirements. It is suitable for other applications such as broadcast, instrumentation, routers, servers and security networks, as well as ATE and automation equipment.
The NVM175 is available with either 12 or 24V output voltage (with 12V/0.2A standby) and, according to TDK, achieves up to 90% efficiency, less than 1W standby power and RoHS and REACH compliance. Other standard features include a power good signal, remote on/off, remote sense and protection from over current, over voltage and over temperature conditions.
