3-Phase AC/DC DIN Rail PSUs

16 February 2024

TDK-Lambda DRB series of 3-phase AC input power supply units (PSUs) are offered in 24V, 48V and 72V output variants.

Delivering conversion efficiency levels reaching 96.3%, these DIN rail configuration units have a broad input range spanning from 350VAC to 575VAC. They are rated for continuous operation at either 480W or 960W, enabling them to respectively deliver 720W and 1440W boosts for a period of 7s. The 480W-rated models have 65mm x 129mm x 159.3mm dimensions, while the 960W-rated models have 100mm x 129mm x 171.9mm dimensions - thereby helping to minimise space utilisation in tightly constrained application environments. These new convection-cooled PSUs support operational temperatures spanning from -25°C to +70°C, and have a rugged construction that ensures long-term reliability. They comply with IEC/EN/UL/CSA 62368-1, 61010-1 and 61010-2-201 standards.
