      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • B&R 5AC901.BUPS-01 allows a compatible industrial PC UPS to bridge an interrupted supply while the operating system completes its configured shutdown sequence.
      Battery technology: Valve-regulated lead acid, rechargeable
      Battery arrangement: 2 x 12 V, connected in series
      Pack nominal voltage: 24 V DC
      The unit contains two 12 V, 2.2 Ah valve-regulated lead-acid batteries connected in series. The resulting pack is rated 24 V and 2.2 Ah; series connection increases voltage rather than doubling ampere-hour capacity.

      An NTC temperature sensor allows the UPS to monitor the battery condition. Operation is specified from 0 to 40°C. Outside the permitted battery temperature range, both charging and backup operation are disabled; the temperature alarm has 5°C hysteresis.

      This battery unit is intended exclusively for the 5AC901.IUPS-01 UPS module. Backup time depends on the connected load, state of charge, temperature and battery ageing, so no fixed runtime follows from the battery capacity alone.
      Controller platform reference: B&R UPS Battery. Use the applicable installation instructions.
      Original B&R technical material applicable to 5AC901.BUPS-01, covering function, interfaces and operating limits. Installation topics include: ups pairing checks, temperature supervision checks, charging interval checks.
      Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.
      System and supply context: The ups battery is applied in the Normal DC input / 5AC901.IUPS-01 / 24 V battery reserve / PC shutdown arrangement. Select associated equipment for the actual channel or installation.

      Application scope: The technical values apply to this model in the specified installation and configuration. The examples below address the stated product function.
      Prepare B&R 5AC901.BUPS-01 for its configured installation using these checks.
      Identify the compatible UPS module

      Read the UPS label before connecting the battery pack.

      Separate backup energy from normal power

      Place the PC and process in an approved shutdown state.

      Retain temperature sensing

      Keep the NTC sensor connection with the battery power connection.

      Check the battery environment

      Measure temperature at the battery location rather than relying on cabinet-room temperature.

      Allow the charging interval

      After installing a discharged pack, allow the specified five-hour charging interval before evaluating backup performance.

      Test a representative shutdown load

      Use a controlled loss-of-input test only when the process can tolerate it.

      Alternative Names

      5AC901.BUPS 01 B&R 5AC901.BUPS-01

      Technical notes

      Separate backup energy from normal power: Place the PC and process in an approved shutdown state. Remember that disconnecting the normal supply alone may leave the UPS powered from its battery; follow the PC service isolation sequence before touching connections.

      Allow the charging interval: After installing a discharged pack, allow the specified five-hour charging interval before evaluating backup performance. A partially charged battery can pass a connection check while still being unable to sustain the required PC shutdown.

      Record the demonstrated reserve: Retain the installed UPS identity, charge interval, test load and shutdown result in the service record. Use the observed reserve and the process shutdown requirement to determine whether the backup system is ready.

      FAQ View All FAQ

      • Does 5AC901.BUPS-01 provide 4.4 Ah because it contains two batteries?
        No. The two 12 V, 2.2 Ah batteries are connected in series, producing 24 V at 2.2 Ah.
      • Which UPS module accepts 5AC901.BUPS-01?
        The compatible UPS module is 5AC901.IUPS-01. The battery unit must not be treated as an interchangeable supply for other UPS designs.
      • What happens when 5AC901.BUPS-01 becomes too hot or too cold?
        Outside its permitted battery temperature range, the UPS disables charging and backup operation. The temperature alarm uses 5°C hysteresis.
      • How does the UPS detect the temperature of 5AC901.BUPS-01?
        The battery unit incorporates an NTC temperature sensor. Its connection must be preserved together with the power circuit.
      • How long should a discharged 5AC901.BUPS-01 be allowed to charge?
        The charging time is five hours under the specified charging conditions; typical charging current is 0.88 A.
      • Why is the backup duration of 5AC901.BUPS-01 load-dependent?
        Runtime changes with PC power demand, available charge, temperature and battery ageing. Capacity alone does not establish a guaranteed shutdown interval.
      • What storage maintenance does 5AC901.BUPS-01 require?
        Recharge the battery at least every six months during storage and keep it within the permitted storage temperature range.
      • Can 5AC901.BUPS-01 maintain its maximum service life at elevated temperature?
        Service life is specified up to five years at 20°C and depends on operating cycles. Higher temperature and repeated discharge affect battery ageing.
