Power Supplies Approved for BF Type Medical Applications

TDK-Lambda introduces the NVM175 series of medically-approved AC-DC power supplies. Combining 4.5 kVAC reinforced input to output isolation with dual input fusing and an output-to-ground isolation of 1,500 VAC, the NVM175 meets UL/EN/IEC60601-1 and is suitable for use in BF (body floating) type medical applications (e.g., Ultrasound, ECG, patient monitors, etc.).

Offered in a compact 5 x 3 in. footprint with less than 1 U height (only 1.02 in. high component height), the NVM175 supplies have universal AC input and are rated at 180 W at 50°C with user supplied air flow. Leakage current is a very low 80 µA maximum with 120 VAC/60 Hz input.

The NVM175 is available with either 12 or 24 V output voltage (with 12 V/0.2 A standby). As well as the impressive technical performance, the NVM175 meets TDK-Lambda’s design brief for environmentally responsible products by achieving up to 90% efficiency, less than 1 W 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.
