Overview
The TDK-Lambda DRB480-24-3-A1 is a three-phase input 480 W DIN-rail AC-DC power supply with a 24 V DC output. Instead of the single-phase 90-264 VAC input of the DRB480-24-1, it accepts a 300 to 575 VAC three-phase input (390 to 810 VDC), with a typical efficiency of 95.1%.
Three-phase DIN-rail supplies are used in heavy industrial and process-control cabinets where only a three-phase rail is available. The DRB480-24-3-A1 delivers a regulated 24 V rail at 480 W with power-factor correction and the same slim DIN-rail format as the rest of the DRB family.
Key Benefits
Three-phase 300-575 VAC input · 480 W at 24 V DC · 95.1% typical efficiency · PFC · slim DIN-rail package.
Applications
Heavy-industrial and process-control cabinets, three-phase machine power, factory automation, and any DIN-rail installation fed from a three-phase supply.
