The UKCA Mark – Selling Into the UK After Brexit
By Andrew Johnson, Director of Product Management The withdrawal of the UK from the European Union or “Brexit” has been a turbulent journey for both sides, concluding on December 31, 2020, with the end of the “transition period” during which negotiations have taken place on new mutual trading arrangements. One of the consequences of Brexit […]
The Latest on IEC 62368-1: The Time to Act Is Now
By Andrew Johnson, Director of Product Management New safety standards based on IEC 62368-1 are superseding existing standards worldwide. In a move that keeps things simple for product vendors, regulators in the US and EU have decided to harmonize the date the new standards will supplant the outgoing 60950-1 and 60065 standards. This harmonized date […]

Prepare for IEC 62368-1, the new hazard-based safety standard
Get ready to evaluate safety measures in a different way. JEFF SCHNABEL, CUI THE FAMILIAR 60950-1 AND 60065 SAFETY STANDARDS for information and communication technology (ICT) and audio-visual (AV) equipment are being phased out in 2020, in favor of a single, harmonized standard based on a more modern approach to safety and testing. OEMs must […]
Finalists announced for prestigious power electronics LEAP Awards
Four finalists were announced Friday for the inaugural LEAP Awards’ Power Electronics Category, comprising a broad array of new advances in power semiconductor and power management technology. The competition was scored by a panel of independent technical/engineering judges. This year’s inaugural LEAP Awards competition honored ground-breaking new products that set a new standard for innovation. […]
Rotary encoders, Part 2: magnetic encoders
Part 1 of this FAQ looked at the optical rotary encoder, a low-cost, high-resolution, easy-to-use sensor for indicating incremental shaft position (although it can be “upgraded” to indicate absolute position as well). Q: What is the basic principle of the magnetic encoder? A: The magnetic encoder uses a rotating gear made of ferrous metal and […]

Early warning for EMC problems
Engineers who wait until the end of the design phase to check for unwanted electromagnetic emissions run the risk of incurring big delays. Bruce Rose | CUI Inc. One design activity often left to the end of a project is the verification a product meets electromagnetic compatibility (EMC) emissions requirements. Considering EMC compliance earlier in […]
Open-frame supplies hit 30 W/in3 densities
The VOF‑180 and VOF‑225A series, outputting 180 W and 225 W of continuous power respectively, feature high efficiencies up to 94% and high power densities up to 30 W/in3. Housed in compact, low profile packages measuring as small as 2x4x0.75 in. (50x101x19 mm), these ac-dc power supplies provide space and energy saving benefits for IT […]
