Features

Compact DC-DC UPS with a DIN-rail for mounting, best suited for the prevention of voltage drop and power failure in industrial PCs (IPC)/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/RS- 232C/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.
