The DRS-240-24 is a 240W all-in-one intelligent DIN rail power supply designed for security systems, industrial automation, and backup applications requiring continuous operation. It combines a power supply, DC-UPS function, battery charger, and monitoring system into a compact unit. The device supports a universal input range of 90–305VAC and includes advanced features such as adjustable charging current, selectable 2-stage or 3-stage charging modes, load-dependent high-speed battery charging, built-in MODBus communication (CANBus optional), and multiple relay alarm outputs for AC fail, battery low, charger fail, and DC-OK conditions. The unit incorporates comprehensive protection functions including short circuit, overload, overvoltage, overtemperature, battery reverse polarity, and battery cut-off protection. Designed for industrial environments, it supports DIN rail mounting and operates in temperatures from −30°C to +70°C using natural air convection cooling.
