DIN rail power supply features a current adjustment function

DIN rail power supply features a current adjustment function
To meet the growing demand for DIN rail power supplies, due to facility minimisation and system management, MEAN WELL has introduced the 40W DRA-40 and 60W DRA-60 series. As well as conventional DIN power supply functions, such as output voltage adjustment, the series also features a current adjustment function. This allows users to adjust the output current, via 1-10VDC, PWM signal, or resistance and thus provides flexibility.

A hybrid approach to inverter efficiency and performance improvement

A hybrid approach to inverter efficiency and performance improvement
Silicon carbide (SiC) devices have the potential to unlock significant performance and efficiency improvements in applications ranging from rail traction to renewable energy generation. This paper describes how the introduction of hybrid technologies that combine these performance and efficiency advantages with the high-power handling capabilities of silicon injection-enhanced gate transistors (IEGTs) is providing engineers with an effective way of significantly reducing losses while minimising equipment size.
