In recent years, there are more and more industrial electronic apparatus designed in the way that the whole system is configured into one cabinet as a unit or the key equipments and accessories are simply set up by a DIN rail configuration, in order to account for facility minimization and system management. It is expected that the market will have more and more demands for DIN rail power supplies in the function perspective. MEAN WELL is now introducing the 40W DRA-40 and 60W DRA-60 series, in addition to the general DIN rail power supply functions (ex: output voltage adjustment, frequently-used protection functions, and so on), also featuring the current adjustment function. This function allows the users to adjust the output current, via 1~10Vdc, PWM signal, or resistance, and thus provides the great flexibility for system design. A lot of the applications adopting LED lighting are able to change the LED brightness with current adjustment equipped on DRA-40 and DRA-60.
DRA-40 and DRA-60 can be mounted on TS-35/7.5 or TS-35/15 DIN rail. They accept the full range 90~264VAC input and provide two different models with 12VDC and 24VDC, respectively. These two series are both designed without the built-in fan and the working efficiency is up to 87% that they can work at the ambient temperature -30~+70°C under air convection cooling. Other standard functions comprise short circuit protection, overload protection, over voltage protection, and front panel DC voltage adjustment. DRA-40 and DRA-60 are certified with UL/CUL/CB/TUV/CE safety regulation and meet the requirement of IEC60950-1 Limited Power Source (LPS). Suitable applications include machine vision inspection systems and the plant cultivation system with LED light source.
