S8BA

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 24 VDC power supply is backed up for a certain period of time in the event of voltage drop or power failure.
  • Compact, weight reduction, and long battery life thanks to the adoption of a lithium-ion battery.
  • Push-in terminal block adopted for the power input and output connections.
  • Shutdown in conjunction with the IPC or controller realized by the USB, RS-232C, I/O port installed in the UPS.

1. 16.7 A/400 W for use as a UL compliant device.

2. 400 W for use as a UL compliant device.

3. 20 A for use as a UL compliant device.

4. 16.7 A for use as a UL compliant device.

5. An estimated value for standard mounting. Not a guaranteed value.

6. When using in an environment at a high temperature, charging may be paused by charging temperature protection, then the charging time will be longer than specified time.
“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.

8. Conditions: With rated loads connected, at a rated input voltage, and with the battery fully charged.

9. Conditions: With rated loads connected, at a rated input voltage, and at the maximum battery charging current.
