New Product Uninterruptible Power Supply (UPS) S8BA Compact DC-DC UPS mounts to DIN rail, best suited to prevent sudden power loss in industrial-purpose computers (IPC)/controllers due to voltage drop or power failure 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. Refer to Safety Precautions on page 12.
