The DRB240-24-3-A1 is a 240W, three-phase input, DIN rail mount AC-DC power supply with a 24V output and push-in wire terminals. It measures 55 mm wide, 129 mm high, and 138.2 mm deep, and is designed for mounting on TS-35/7.5 or TS-35/15 DIN rails. The unit operates from 350 to 575 Vac, delivers up to 12 A peak current for 2 seconds, and achieves 93.8% efficiency at 500 Vac. It includes a DC Good relay, remote on/off control, and supports parallel operation with droop mode current sharing. The power supply meets IEC/EN/UL/CSA 61010-1, 61010-2-201, and 62368-1 safety standards, complies with EN55011-B and CISPR11-B EMI limits, and is rated for operation from -25°C to +55°C full load, with derating above 55°C. It has a 10-year typical capacitor life and weighs 780 g. The unit features low inrush current, less than 2 W no-load consumption, and a 3-year warranty.
AC-DC converters have the functionality to extract a stable DC power supply by rectifying and controlling commercial power supplies. TDK offers an abundant lineup of TDK-Lambda brand AC-DC switching power supplies that adopt the "switching method" for the industrial equipment market. These power supplies are available in unit types, PC board types, power module types, on-board types, and DIN rail mount types, with a wide-ranging product lineup from models with a small capacity of several W to models with a large capacity exceeding 2 kW. TDK-Lambda offers "standard power supplies" that meet the various needs of its customers for keeping up with the changing times, including miniaturization and efficiency enhancement, compliance with safety standards, support for wide input, compliance with EMI (electromagnetic interference) standards and higher harmonic current regulation, compliance with the RoHS directive, and the adoption of digital control technologies.
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.
