DC-DC type small UPS mounts on a DIN rail to provide an ideal countermeasure for momentary power losses and power failures in industrial computers (IPC) and controllers.• System reliability greatly improved because 24VDC power supply is backed up for a certain period of time in the event of voltage drop or power failure.• Compactness, weight reduction, and long battery life realized thanks to the adoption of a lithium-ion battery.• Push-in terminal block adopted for the power input and output I/F.• Shutdown in conjunction with the industrial purpose computer (IPC) or controller realized by the USB/RS232C/I/O port installed in the UPS.• Two types of batteries are selectable for the 480W, allowing the ideal backup time to be realized• A wide lineup culminating in the 960W makes it possible to provide long-lasting backup for every type of industrial controller
