Position encoders are widely used in motion control applications and many different types are available. To choose the optimum device for a given application, engineers must decide between absolute, incremental or commutation encoders, which present data in various formats such as quadrature, motor-pole or a serial protocol. The resolution required, as well as dimensions and […]
Why is it vital to include power factor in ac-dc efficiency measurements?
Ron Stull of CUI explains what power factor is, how it affects efficiency calculations and how it is measured With today’s concentration on energy savings, design engineers need to know with increasing accuracy what their ac-dc power converter efficiency is. Measuring the ratio of output power to input power is simple for dc-dc converters, but […]
Understanding MTBF and the principles of reliability engineering
The Mean Time Between failures (MTBF) quoted in a product datasheet is often incorrectly assumed to provide a direct indication of expected lifetime. In fact, reliability is a statistical concept – it is the probability that an individual unit of any given product, operating under specified conditions, will work correctly for a specified length of […]
External power supply line meets new IEC 62368-1 standard
CUI’s Power Group today announced that it has upgraded the majority of its external ac-dc power supplies to the new IEC 62368-1 standard for ICT and AV equipment. Set to supersede the outgoing IEC 60950-1 and IEC 60065 standards on December 20, 2020, IEC 62368-1 will introduce fundamentally different guidelines based on hazard-based safety engineering principles. […]
Chassis mount ac-dc power supplies housed in low-profile metal case
CUI’s Power Group today announced a new line of compact, chassis mount ac-dc power supplies housed in an enclosed metal case. The VGS‑B series offers power ratings from 35 to 350 W with low 30 mm profiles and compact packages as small as 99 x 82 x 30 mm (3.89 x 3.22 x 1.18 in). […]
How to specify the proper Peltier module for your design
The latest generation of Peltier cooling modules can be a powerful addition to a designer’s thermal management toolbox. Robust and reliable, they can cool an IC or various other components – such as an LED or laser diode – to a target temperature and ensure stability even if the load changes rapidly. The modules are […]
How USB Type-C connectors hold the key to maximizing data speeds and power delivery
Bruce Rose, CUI The new USB Type-C connector should become a common sight in new laptops and mobile devices over the next couple of years. Smaller and easier to use – allowing plugs to be inserted in either direction – the new mechanical interface has all of the features needed to support the advanced USB electrical […]
CUI partners with SnapEDA to offer free PCB footprint files
CUI today announced that it has teamed up with SnapEDA to provide designers with a catalog of free, ready-to-download PCB footprints and symbols for CUI’s range of board mount electromechanical components. Circuit board design has historically been a time-consuming and challenging process due to the variety of product configurations and standards. With this partnership, users will […]
An introduction to audio jack switches and schematics
Standard 2.5 mm or 3.5 mm audio jacks are found in a huge variety of consumer and professional audio products. Widely recognized, easy to use and simple in concept, they can be applied in many ways to enhance convenience for users and manage various features and functions of a product that are not necessarily related […]
1-W ac/dc supplies come in ultra-compact SIP packages
CUI’s Power Group today announced the addition of two models to its PBO family of ultra-compact ac-dc power supplies. Outputting 1 W of continuous power, the open frame PBO‑1 and PBO‑1‑B series are housed in vertical and right-angle SIP packages, respectively. The vertical PBO‑1 series measures as small as 35 x 11 x 18 mm […]
