In summary, the DRB (120-240 W) series accepts an input voltage of 350 to 575 VAC, with the 120 W having 12 V and 24 V outputs and the 240 W having 24 V and 48 V outputs. For higher power or redundant systems, units can be connected in parallel. A DC good signal and remote on/off function is also included. With efficiencies of up to 94%, less internal heat is generated, enabling a smaller, 55 mm wide package size without compromising reliability. The units can operate in ambient temperatures of -25 to +70°C, derating above 55°C. Nuisance input circuit breaker tripping is minimized by the DRB’s low inrush current energy. The series has a robust metal case and rigid mounting on the DIN rail.
