MEAN WELL DRS-480-48, Programmable backup power supply for DIN rail 480W, 48V

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

Flexibility that meets strict standards

The programmable backup source allows for configuration of signals and alarms via the communication interface. With the option to set 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 adapted to the system requirements. It is suitable for lead and lithium-ion batteries and supports charging curve adjustment using the SBP-001 tool for maximum lifespan and safety of the batteries.

Intelligent backup management with advanced features

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