S8BA Integrated battery type

Compact DC-DC UPS with DIN-rail prevents 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.

“CS” will be displayed when charging temperature protection is operated.

7. For the S8BA-24D24D120LF, install all of the RSMN-2030, RSHN-2030, and RSEN-2030 EMC filters manufactured by TDK. For the S8BA-24D24D240LF, S8BA-24D24D360LF, or S8BA-24D24D480LF, install both the RSMN-2030 and RSHN-2030 or their equivalents. Install these filters in series to the cable connected to the DC input terminal block. When you do, do not connect anything to the GR terminal.
The effectiveness of the noise filters may be affected by the installation environment. Be sure to check effectiveness before starting operation.
