MEAN WELL DRS-480-24, Programmable backup power supply for DIN rail 480W, 24V

The "all-in-one" solution combines AC/DC power supply with a power of 480 W, DC-UPS system, intelligent battery charger, and a monitoring unit in a compact design for DIN rail mounting. With a universal input of 90–305 V AC and cooling by free convection, it is ideal for industrial and security applications that require stable power and backup in one device. Support for installation on TS-35/7.5 or 15 DIN rail allows easy integration into existing systems.

Flexibility that meets strict standards

The programmable backup source allows configuration of signals and alarms via a communication interface. With the ability to set the charging current in the range of 20–100 % and the choice between 2 or 3-stage mode using a DIP switch, the unit can be precisely tailored to the system's requirements. It is suitable for both lead and lithium-ion batteries and supports charging curve adjustment using the SBP-001 tool for maximum battery life and safety.

Intelligent backup management with advanced features

Ensure reliable operation of your system with type C relay contacts and clear LED indicators for AC status, battery, charger, and output. The device supports fast battery charging according to the current load, increasing efficiency during backup power. Communication is ensured via MODBus with an optional CANBus interface, ideal for industrial applications. Advanced protection against overvoltage, shorts, overheating, and reverse polarity is standard, ensuring safe and stable operation without damage to the device.
