The DRB240-24-3-A7 is a 240W, 24VDC DIN-rail power supply with push-in terminals and conformal coating for harsh environments. It accepts AC input 342-575VAC or DC input 450-810VDC, delivering 10A nominal and boost currents of 12A for 300s or 15A for 60s. Efficiency reaches 94.8% under DC input, with no-load consumption below 3.0W. It includes DC-OK and inhibit relay contacts, parallel mode for load sharing, and an integrated GDT for surge protection. The unit complies with IEC EN 61010-1, IEC EN 62368-1, UL CSA 61010-1, UL CSA 62368-1, and EU directives for Low Voltage, EMC, and RoHS. It measures 55 x 129 x 138.2mm, weighs 780g, and operates from -25°C to +70°C with a minimum MTBF of 1.8M hours at full load.
The DIN-Rail power supplies in the DRB series are part of TDK-Lambda’s industrial heritage. They can be used in many applications, ranging from conventional switch cabinets and decentralised machinery and systems, to renewable energy and charging solutions. The series covers the popular output voltages of 12, 24, 48 and 72 volts, and users can operate them, both with AC or DC voltage.
The DRB’s high operating efficiencies, the use of high-quality electrolytic capacitors and the integration of a gas discharge tube provide maximum system up-time.
Special models featuring conformal coating are available for use in challenging environments containing corrosive gases. Overall the DRB 3 phase series offer an excellent balance between functionality and price.
