MEAN WELL DRS-240-24, Programmable backup power supply for DIN rail 240W, 24V

The "all-in-one" solution combines AC/DC power supply with a power of 240 W, 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 supply and backup in one device. Support for installation on 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 a communication interface. With the option 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 requirements. It is suitable for lead and lithium-ion batteries and supports adjustment of the charging curve using the SBP-001 tool for maximum battery life and safety.

Intelligent backup management with advanced features

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