Housed in […]
Senior managers purchase CUI Inc’s electronic components business and form CUI Devices
Former senior managers of CUI Inc announced that they have purchased the company’s industry-leading components business from CUI Inc’s publicly-traded parent company, CUI Global. The newly-formed private entity will go to market as CUI Devices and will continue to serve its customers and develop new technologies within its interconnect, audio, thermal management, motion and sensors product […]
How to design a Peltier module system
Thermoelectric cooling, using a Peltier module, gives designers flexibility to cool objects to a precisely controlled temperature, even below the ambient temperature of the application if required. It is a great choice if forced-air cooling is not possible, and a thermoelectric device is typically smaller, lighter and more energy-efficient than cooling using a compressor and […]
Next-gen 6-W wall plug-in ac-dc supply has interchangeable ac blades for global use
CUI’s Power Group today announced the introduction of a next-generation 6 W wall plug-in ac-dc power supply with interchangeable ac blades designed for global use. The SMI6B series features an ultra-compact package measuring 1.85 x 1.36 x 1.04 in (47 x 34.5 x 26.5 mm), while complying with the US DoE Level VI and EU CoC […]
What you need to know about buzzers – reviewing the basic types and technologies
Bruce Rose, Principal Applications Engineer, CUI Inc A buzzer can provide a cost-effective yet intuitive aspect to the user interface of a wide variety of products, such as a home appliance, security panel, door-entry system or computer peripheral. Usually, the choice is between either a magnetic or piezoelectric type. It should be an easy decision, […]
Power operating limits: How to choose the right power supply
Not all power supplies react to over and under-voltages and currents in the same way. It pays to know the tradeoffs of different approaches to protection. Ron Stull | CUI Inc. Power supplies can experience operating conditions outside normal specified limits, such as input under- or over-voltage, or variations in load and ambient temperature. These […]
Low-power, encapsulated ac-dc power supplies include 3-W and 5-W models
CUI’s Power Group today announced the addition of 3 W and 5 W models to its line of low power, encapsulated ac-dc power supplies. Available in board mount, chassis mount, wire lead, and DIN rail configurations, the single output PSK‑S3 and PSK‑S5B series are housed in compact packages measuring as small as 1.46 x 0.97 […]
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.
