TDK-Lambda’s NVM175 power supplies meet latest medical approvals

TDK-Lambda’s NVM175 is now approved to IEC/EN 60601-1, ANSI/AAMI ES60601-1 and CAN/CSA-C22.2 No 60601-1-08 3rd Edition medical safety standards. This is in addition to the current approval to the 2nd Edition, ensuring full safety approval for medical equipment is maintained during the transition period from 2nd to 3rd Editions. Typical applications for the NVM175 range include medical, industrial control, computing, automation, security, network servers and routers, broadcast, communications, lifesciences/laboratory, instrumentation and ATE.

Available with either 12 or 24V output (with 12V/0.2A standby), the NVM175 supplies have universal ac input and are rated at 180W at 50°C with customer air. Leakage current is less than 200µA at 264Vac/63Hz surpassing worldwide medical equipment requirements. Achieving up to 90% efficiency and consuming less than 1W standby power, the NVM175 meets TDK-Lambda’s design brief for environmentally responsible products.

Other standard features include a power good signal, remote on/off and remote sense, as well as protection from over current, over voltage and over temperature conditions.
“We are approved by the Underwriters Laboratories Inc. (UL) to 60601-1 3rd Edition, which helps us to ensure that our medical power supplies are tested and approved to the highest safety standards,” says Bob Taylor, Safety Engineering Manager at TDK-Lambda UK.

The power supply manufacturer has actively participated in the Underwriters Laboratories Inc. (UL) ‘Clients Test Data Program’ (CTDP) and the IECEE CB Scheme SMT (Supervised Manufacturer’s Test) Program, which is now also under the supervision of UL, for over 16 years. Being on these programs allows TDK-Lambda to use its own testing facilities to generate UL and CB safety reports and test data, this capability helps to reduce time and the accompanying costs for the safety approvals of its own AC-DC power supplies and DC-DC converters.

In addition to 60601-1 3rd Edition, all models in the TDK-Lambda NVM175 range are approved to IEC/EN/UL/CSA 60950-1 for general purpose applications and IEC/EN/UL/CSA 61010-1 for laboratory and process control applications, as well as meet Class B conducted and radiated EMC EN55011 and EN55022. The NVM175 also carries the CE mark, according to the LV Directive, and comes with a 3-year warranty.
