The DRB480-24-1 is a 480W DIN rail power supply designed for industrial and process control applications, providing a nominal 24V output at up to 20A. It operates over a wide input range of 85-264Vac and features high efficiency of up to 92% at 230Vac, minimizing power loss. The unit includes overvoltage and overcurrent protection, a DC OK indicator with an opto-isolated signal for remote monitoring, and convection cooling in a compact 84mm wide case. Its robust design, compliance with industrial safety standards, and long calculated MTBF make it a reliable power source for demanding system environments.
