Description
The TDK-Lambda DRB120-48-1 is a space-saving, high-efficiency DIN rail power supply that delivers 48VDC at 2.5A (120W), ideal for use in industrial automation, process control, and signal equipment. Its adjustable output range from 48 to 52.8VDC allows flexibility across a range of load conditions, and its boost capability up to 3A (144W) supports temporary overloads such as start-up surges.
This model offers up to 91% efficiency, reducing heat generation in compact enclosures, and includes a rugged 35mm-wide DIN rail housing suitable for TS35 rails. The DRB120-48-1 supports global operation with universal AC input (85–264VAC) and meets all key safety and EMC standards, making it an excellent fit for professional and regulated installations.
