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 […]

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 […]
