AC-DC power supplies for budget-conscious applications
XP Power announced the introduction of the LCS series of regulated output, convection cooled AC-DC power supplies that are well-suited to budget-conscious applications. The four new series (LCS35, LCS50, LCS75, and LCS100) offer power levels of 35W, 50W, 75W, and 100W, respectively, and feature class B conducted and radiated emissions for easy & low-cost system […]
Titanium efficiency 4-kW supplies target OCP, CORD, datacenter apps
Bel Power Solutions announced the TET4000-48-069RAH, a 4000 W power supply designed to provide the highest efficiency (Titanium) power conversion for data centers being built to Open Compute Project (OCP), Open Data Center Committee (ODCC), or Central Office Re-architected as a Datacenter (CORD) standards. The TET4000-48-069RAH is the highest power 48 VDC model in Bel […]
General-purpose high-current, high-voltage power supplies include isolated outputs
Lumina Power has announced the release of the new 10 Channel LPS series general purpose high current, high voltage power supplies for the Electroplating and Specialty Markets. The new 10 Channel Series includes two sets of isolated outputs, with five individual outputs per set. Each set has its own common cathode. The new line consists of 5 […]
Reference design based on 4-kW high-efficiency single-phase ac-dc evaluation board
A new power supply reference design enables engineers to identify and correct design errors before building hardware, thereby lowering product costs and speeding time to market. Switched-mode power supplies provide greater efficiency, increased power density and lower overall system costs when using GaN devices. However, GaN, a high switching speed, high performance wide bandgap semiconductor, […]
How to boost output hold-up time in power supplies
Many supplies have outputs that don’t stay up long enough in the event of a power loss. Here are some ways to remedy the problem. TDK-Lambda Americas An ac-dc power supply’s input voltage can be interrupted during circumstances such as a brown out condition or a brief power failure. When this happens, the dc output […]
Titanium-Efficiency 3.2 kW supplies optimized for server intermediate-bus architectures
Bel Power Solutions announced the expansion of their portfolio to include the TET3200-12-069RA, a 3200 W Titanium efficient AC-DC front-end power supply that can convert up to 277 VAC into the main output of 12 VDC for powering intermediate bus architectures (IBA) in high performance and high-reliability servers, routers and network switches and applications. The […]
The changing maze of power supply standards
Brexit altered the landscape of standards for power supply products. Here’s an update on the latest revisions. Ron Stull CUI Inc. The usual way of choosing a power supply is to search on the electrical performance parameters the application demands. But today, it is actually more efficient to start with the national or international standards […]
Picking reliable power supplies
A few basic parameters can be useful for selecting power supplies that must work dependably in specific application scenarios. Alex Karapetian Acopian Power Supplies Electronic devices require a reliable source that can supply power at all times. But power supplies are available in a wide range of voltage and current ratings. Engineers tasked with selecting […]
Silent convection-cooled supplies put out 750 W
Bel Power Solutions announced the ACC750 (industrial) and MCC750 (medical) Series of convection cooled power supplies which are available in a couple of single output voltages. The natural convection cooling operation (without a fan) is particularly suitable for environments sensitive to acoustical noise. The ACC/MCC750 Series provides up to 750 W (900 W peak for <10 […]
