Smallest 40W AC/DC open frame power supply launched

The ECF40 series from XP Power consists of single output 40W compact AC/DC power supplies. These open frame convection-cooled units are said to be capable of delivering 40W in temperatures of up to 50°C without the need for any external forced air flow.

Measuring 76.2 x 38.1 x 28.0mm, the ECF40 is believed to be the smallest 40W open frame power supply available on the market. The modules suit a range of applications in the healthcare, industrial and technology sectors, across temperatures ranging from -40 to 70°C.

The range comprises six models providing all the popular nominal output voltages from 12 to 48V DC.The voltage on all models can be manually trimmed ±10% via a user accessible potentiometer on the supply.

According to the company, the series consumes less than 0.15W during no load conditions, helping designers ensure their end product can comply with energy efficiency standards. In addition, with an efficiency of 90% or higher, the flat efficiency curve is said to ensure that the ECF40 consumes less energy than other similar supplies available on the market and runs cooler, helping maintaining overall product reliability.

The ECF40 series is certified to the ITE IEC/UL/EN 60950-1 and IEC/EN60601-1 / ANSI/AMMI ES60601-1 3rd edition medical safety standards and provide two means of patient protection. The series also feature 4000V A/C input to output isolation, two AC line fuses and a maximum of 250µA leakage current.

The units operate at full power over an input ranging from 90 to 264V A/C and down to 80V A/C with minimal derating. Models comply with Class B conducted EMC specification without the need for any additional external filtering components.
