Quartet of power supplies meet latest medical safety approvals

July 13, 2012 // Paul Buckley

TDK Corporation's TDK-Lambda NV175 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.

The recent approval 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 NV175 range include medical, industrial control, computing, automation, security, network servers and routers, broadcast, communications, lifesciences/laboratory, instrumentation and ATE.

Four highly efficient 180 W (200 W peak power) NV175 units are available on rapid delivery, although additional variants can be built to order. Earth leakage current is less than 300 µA at 264 Vac/63 Hz making it suitable for worldwide markets. Operating inputs range from 90 V to 264 Vac, with up to five outputs offered, covering the 0.9 V to 28 V range. The NV175 range includes multi-output versions with an optional temperature-controlled fan to ensure optimum cooling whilst achieving the lowest possible audible noise performance. Despite the more substantial insulation requirements demanded by 60601-1, the NV175 fits 1U applications.

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 NV175 range are approved to IEC/EN/UL/CSA 60950-1 for general purpose applications and IEC/EN 61010-1 for laboratory and process control applications, as well as meet Class B conducted and radiated EMC EN55011 and EN55022. The NV175 also carries the CE mark, according to the LV Directive, and comes with a 3-year warranty.
