Board Mount 15W to 60W AC-DC Power Supplies Have Medical and ITE Certifications

TDK Corporation announces the introduction of the TDK-Lambda KMS-A 15W to 60W board mount AC-DC medical and ITE certified power supplies. Capable of starting up at -40oC, the convection cooled units will operate in ambient temperatures of up to 80oC and are rated for full load over a -30 to 50oC range. The KMS-A series is designed for use in a wide range of medical and industrial applications, including dental, home healthcare and test and measurement.

Murata DC-DC converter powers gate drives for optimal performance and efficiency

Murata has announced the MGJ1 1 Watt DC-DC converter series manufactured by Murata Power Solutions. These compact devices are ideal for driving high and low-side gate circuits such as those using IGBTs and SiC MOSFETs for optimal efficiency. With high isolation characteristics, up to 5.2 kVDC, the MGJ1 offers the popular nominal output voltage combinations of +15 / -5, +15 / -9, or +19 / -5 VDC. The series also offers a choice of +5, +12, or +24 VDC input.

10 W Ac-Dc Power Supplies with Integrated USB Connectors Meet DoE Level VI and CoC Tier 2 Standards

CUI today announced a new line of DoE Level VI and CoC Tier 2 compliant wall plug-in ac-dc power supplies featuring an integrated USB connector. The 10 W SMI10-USBSWI10-N-USB and SWI10-E-USB are all designed to meet the stringent average efficiency and no load power requirements mandated by the US Department of Energy (DOE) in effect since February 2016. Any domestic or global manufacturer seeking to market their end product with an external adapter in the United States must meet the new Level VI standardswhich aim to significantly lower the amount of power consumed when the end application is not in use or is no longer connected to the system. The models also meet the European Union’s January 2018 CoC Tier 2 directive that will add additional power consumption limits at 10% load levels.

Today Vicor released four new DCM products in the VIA package

Today Vicor released four additional DC-DC converters that are deployed in the rugged, chassis-mountable versions of its DCM™ family of isolated, regulated DC-DC converters. These new products extend the family by adding two 270V and two 28V nominal products
to the family. (See Table 1)

250W Medical and ITE 3x5” Footprint Power Supplies are 94% Efficient

TDK Corporation introduces the TDK-Lambda CUS200M series of medically and ITE certified power supplies.  Featuring efficiency levels of up to 94%, internal heating is reduced allowing electrolytic capacitor life to be extended.  The CUS200M can deliver 200W convection cooled and up to 250W with 1.5m/s airflow and is packaged in the industry 3” x 5” standard footprint.  Applications include hospital, dental, broadcast, test and measurement equipment, particularly where audible fan noise is not desired.
