The DRB120-24-3-A7 is a 120W, 24VDC DIN-rail power supply with push-in terminals and conformal coating for enhanced protection in harsh environments. It operates from AC input ranges of 342 to 575VAC or DC input of 450 to 810VDC, with a nominal output current of 5A and boost current capability up to 7.5A for 600 seconds. The unit achieves typical conversion efficiencies of 91.2% to 92.4% under AC and DC inputs, respectively, and maintains an ambient operating temperature range of -25 to +70°C. It features DC-OK and inhibit relay contacts, integrated GDT for surge protection, and meets IEC EN 61010-1, IEC EN 61010-2-201, IEC EN 62368-1 (Ed.3), UL CSA 61010-1, UL CSA 61010-2-201, UL CSA 62368-1 (Ed.3) safety standards, as well as EU Low Voltage, EMC, RoHS, and Hazardous Substances Directives. The device measures 55 x 129 x 138.2mm and weighs 660g.
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.
