The DRS-240 is a 240-W AC/DC safety power supply series for DIN rails. In addition to the primary output, there's an additional charging circuit that automatically adjusts the charging current to the primary output current. The DRS-240 operates in the universal input range between 90 V AC and 305 V AC, and supports output systems with a nominal voltage of 12 V DC, 24 V DC, 36 V DC or 48 V DC. With a high efficiency of up to 92%, it can be operated using convection cooling at ambient temperatures from -30°C to 70°C.
