TDK-Lambda's digital power supplies achieve medical approvals

March 09, 2012 // By Paul Buckley
TDK Corporation’s TDK-Lambda EFE300M 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 medical applications for the EFE300M range include clinical diagnostic systems, medical imaging equipment, dialysis systems and medical lasers. With a 6x3 inch footprint and a 1U profile, the EFE300M can be incorporated easily in designs where space is limited, so end equipment can be smaller, cooler and more feature rich. Other features such as redundant operation (complete with in-built Oring FET) and a high current standby output make the EFE300M equally suitable for high integrity applications including broadcast, instrumentation, routers, servers and security networks. Other suitable applications include ATE and automation.

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 more than 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 3 rd Edition, all models in the TDK-Lambda EFE300M 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 EFE300M also carries the CE mark, according to the LV Directive, and comes with a five-year warranty.
