Astrodyne has released the SDR-240 series of ultrathin DIN-rail mounted switching power supplies designed for industrial control and embedded systems applications.

The unit width of the power supply series is 50 percent smaller than previous versions. Providing 240W of output power, all models accept universal input from 90- to 264Vac and two models are offered at 24- and 48Vdc with active PFC >0.93 and 93 percent efficient.

The SDR-240 comes with overload, overvoltage, overtemperature protection and features free air convection cooling. The power supplies are enclosed in rugged metal casings that offer a high density, ultrathin package only 2.48-inch wide.

All models in the SDR-240 series provide an integral power-good LED indicator and output adjustment potentiometer and are designed to operate over the ambient temperature range of -25C to +60C without forced cooling or output power derating. All models can be installed on DIN Rail TS35/7.5/15 and are fully approved to UL508 and TUV EN60950-1 safety specifications. Power supply dimensions are 4.46-inch x 2.48-inch x 4.93-inch with screw terminal I/O connections. The SDR-240 series is priced at $119 in OEM quantities with delivery at eight weeks ARO.
