How to design a Peltier module system

September 13, 2019 By Aimee Kalnoskas Leave a Comment

peltier modules

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 […]

Power operating limits: How to choose the right power supply

March 1, 2019 By Lee Teschler Leave a Comment

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 […]

Why is it vital to include power factor in ac-dc efficiency measurements?

October 25, 2018 By Aimee Kalnoskas Leave a Comment

power factor

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

October 8, 2018 By Aimee Kalnoskas Leave a Comment

MTBF

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 […]
