The NQBS modules deliver a power density of 27.2 W/cm3 (445 W/in3) and efficiencies in excess of 96% in a quarter brick package.

A family of digital PoL load DC/DC modules, which address the rapidly-rising power challenges in distributed power architectures, has been announced by CUI. The NDM3ZS-60 is a non-isolated module outputting 60A in ultra low-profile vertical and horizontal packages.

Two isolated DC/DC converter familes, designated the PQMC3-S and PQM3-M Series, have been announced by CUI. The converters increase total efficiency across the entire load curve and deliver improved performance at light and no loads. The coverters have been designed for battery-powered applications where power draw under these conditions are a concern.

CUI Inc annonce l’arrivée de Neil Whittington au poste de directeur commercial EMEA. Cette nomination fait partie des actions menées par CUI pour accroître sa présence en Europe et renforcer le support de ses clients européens.

CUI introduce the new PQA50-D, one of the smallest 50 W DC-DC converters in the industry. Ideally suited for IT equipment, telecom and industrial systems, the PQA50-D DC-DC converter series is a low cost, high performance family with a 50.8 mm x 25.4 mm (2 x 1 inch) footprint - an industry standard size for less powerful devices.

CUI Inc introduit une série d’alimentations ac-dc de 100 W à refroidissement par la plaque de base, de haute performance, encapsulées en boîtier à monter sur carte d’ultra bas profil (17 mm).

CUI Inc annonce ce jour une importante mise à niveau de ses familles de convertisseurs isolés VYB et VYC, avec l'introduction de la famille de convertisseurs dc-dc de haut rendement PYB.

Switching power supplies generate Electromagnetic Interference by virtue of their inherent design characteristics. Internal switching power supply circuits that generate undesirable emissions that are rich in harmonics can cause electrical interference both internally to the circuit in which the power supply is installed and to other electronic equipment in the vicinity of the emission source.

CUI has today announced the release of a new ultra-compact 5 W wall plug adapter with integrated USB connector, the EPSA050100U-I38-EJ. With a footprint of just 41 x 30 mm (1.61 x 1.18 inches), the adapter is among the industry’s smallest AC-DC power supplies to integrate USB.

CUI Inc lance les plus petites alimentations ac-dc de son catalogue à ce jour avec la série PBK ultra-compacte en boîtier SIP. Disponibles en versions de 1 W, 3 W et 5 W, ces modules ne mesurent que 1,38 x 0,43 x 0,94 pouces (35 x 11 x 24 mm), et occupent moins de surface de circuit imprimé que les alimentations AC-DC conventionnelles ; ce qui permet d’économiser de l’espace au cas où il est n&...

CUI introduce the new high efficiency PYB DC-DC converter family. Housed in board mount packages with six-sided shielding, the new family offers an output power range of 10 W - 30 W across four series and features an ultra-wide, 4:1 input range. Efficiencies are also increased significantly over previous generations reaching 91%, up 3 percentage points.

CUI Inc launched their smallest AC/DC power supplies yet with the release of the PBK ultra-compact SIP series. Available in 1 W, 3 W, and 5 W families, the modules measure as small as 1.38 x 0.43 x 0.94 in. (35 x 11 x 24 mm), occupying less pcb real-estate than other conventional ac-dc power supplies, thus allowing designers to fully maximize space where on-board ac-dc power conversion is required. Today, CUI Inc launched their smallest ac-dc ...

Long gone are the days when only engineers that worked with large electric motors and high power electric loads need worry about power factor. The introduction of switching power supplies into electronic systems has led to increasing international legislation, moving power factor up the list as a key concern for most engineers developing systems that run on ac mains power. This paper will help you understand power factor and its implications...

Standards are an integral part of product design and development, and are vitally important in medical applications. With the recent transition to IEC 60601-1 3rd edition, designers of medical equipment must consider a range of new requirements covering design methodology and verification, safety and risk assessment, implementation, and much more. Here we look at the 3rd edition standard and its implications for engineers specifying power supplie...

CUI introduces a family of low-power board mount dc-dc converters that provides 3000 Vdc I/O isolation and an ultra-wide operating temperature range of -40~105°C for the most demanding applications. The unregulated PEM series is the latest addition to CUI’s second-generation low power dc-dc converter line and has been specifically designed to improve efficiency and thermal performance in the customer’s application.

CUI today announced its range of medical power supplies has received IEC 60601-1 3rd edition medical safety certifications. The certification covers 17 product families ranging from 15 W to 400 W, easing compliance for medical device engineers.

CUI has launched a line of board mount dc-dc converters for IGBT gate drivers. Devices in the VQA series provide short circuit protection with 3000 Vac input to output isolation (4242 Vdc), and are ideally suited to provide a fully isolated gate drive for both industrial and clean energy applications, such as wind turbines and solar panels.

The benefits of digital power are well documented, with countless technical articles and analyst reports filling an array of engineering publications. The problems it solves are recognised by both large and small OEMs from the medical, industrial, automotive and almost every other market sector. But, there are barriers to the acceptance of digital power. By Bruce Rose, Technical Marketing Manager for CUI Inc.
