AC/DC Power Supplies Are Medically Approved

TDK-Lambda has introduced 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 1,500VAC, the NVM175 meets UL/EN/IEC60601-1 and is said to be suitable for use in BF-type medical applications. Offered in a 5 x 3in footprint with less than 1U height, the NVM175 supplies have universal AC input and are rated at 180W at 50C with customer air.

Leakage current is less than 200uA at 264VAC/63Hz surpassing worldwide medical equipment requirements. It is equally suitable for many other applications including broadcast, instrumentation, routers, servers and security networks, as well as ATE and automation equipment. The NVM175 is available with either 12V or 24V output voltage (with 12V/0.2A standby). The NVM175 meets TDK-Lambda's design brief for environmentally responsible products by achieving up to 90 per cent 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. Products in the TDK-Lambda NVM175 range meet Class B conducted and radiated EMC EN55011 and EN55022. All models have TDK-Lambda's three-year warranty, as well as EN/IEC/UL/CSA 60601-1, EN/IEC/UL/CSA60950-1 and CE approvals.
