TDK-Lambda News

TDK Corporation announces that the TDK-Lambda Alpha 1000 Series (CA) modular AC-DC power supplies 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 Alpha 1000 series includes medical, industrial control, computing, automation, security, network servers and routers, broadcast, communications, lifesciences/laboratory, instrumentation and ATE.

With an input operating voltage range of between 85 and 264Vac and an input frequency of 47 to 63Hz, the Alpha 1000 has a start-up time of < 50ms. The flexible modular design of the Alpha Series meets the demand for applications requiring voltages that lie beyond that of standard units; with 7 slots, the Alpha 1000 can accommodate an extensive range of single- and twin-output modules to provide up to 14 outputs thus achieving many combinations of Volts and Amps. In addition, voltage output adjustment is via a multi-turn potentiometer with accuracy to within 1%.

“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 Alpha 1000 Series are approved to IEC/EN/UL/CSA 60950-1 for general purpose applications, as well as meet Class A conducted and radiated EMC EN55022. The Alpha 1000 also carries the CE mark, according to the LV Directive, and comes with a 3-year warranty
