The DRB120-24-3-A1 is a 120W, three-phase input, DIN rail-mounted AC-DC power supply with a 24V output, push-in terminal type, and a 22.5 to 29V output adjustment range. It provides up to 12A peak current for 2 seconds and achieves 91.3% efficiency at 400/500Vac input. The unit operates over an input voltage range of 350-575Vac, features a low no-load power consumption of 1.7W, and complies with IEC/EN/UL/CSA 61010-1, 61010-2-201, and 62368-1 safety standards. It supports remote on/off and DC Good relay output, and can be paralleled for redundancy or increased power. Operating temperature range is -25°C to +55°C full load, with derating above 55°C. Dimensions are 55 x 129 x 138.2 mm, mounted on TS-35/7.5 or TS35/15 DIN rails, with an aluminum case and 10-year typical capacitor life. Conduction and radiated EMI meet EN55011-B and CISPR11-B, and immunity complies with EN61000-4 series standards.
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.
