The DRU-24V10ACZ is a Chrome DC-UPS module designed for 24V systems requiring reliable backup power with seamless transition to battery operation. It delivers a maximum output of 10A at 24V (240W) with an input voltage range of 24-28Vdc and supports external sealed lead acid batteries from 3.3AH to 12AH capacity. The module features zero switchover time from AC loss to battery operation, built-in diagnostic monitoring via relay contacts and LED indicators, and comprehensive protection including overvoltage, overcurrent, over-temperature, and short-circuit safeguards. Operating across the full temperature range of -20°C to +60°C with convection cooling, the module achieves an MTBF exceeding 500,000 hours and is certified to major safety standards including UL 60950-1, UL 508, and CB scheme. Its compact form factor (91.0 × 71.0 × 55.6 mm) and DIN rail mounting make it ideal for space-constrained industrial cabinets and control systems requiring continuous power availability.
