  Информационные материалы

  The SITOP PSE201U buffer module bypasses short-term power failures lasting a few seconds and can be used with all 24 V power supplies of the SITOP smart or SITOP modular product lines. The buffer module is equipped with maintenance-free capacitors and automatically takes over the 24 V power supply in case of a power supply failure.

  The SITOP DC UPS modules offer protection in the event of extended power failures. The maintenance-free DC UPS with capacitors are able to reliably supply 24 V for several minutes, and the DC UPS with battery modules for several hours.

  Область применения

  With short-term power failures, the load current is backed up without interruption via the buffer module in combination with a SITOP smart or SITOP modular 24 V stabilized power supply.

  Buffer times:

  • 200 ms at 40 A
  • 400 ms at 20 A
  • 800 ms at 10 A

  You can connect up to 8 buffer modules in parallel to extend the buffer time (max. 10 s).

  

  Дизайн

  The buffer module is connected in parallel to the output of the SITOP smart or SITOP modular power supply. The connection to the power supply takes place via only 2 cables.

  Функции

  Buffering

  In case of a power failure, the buffer module supplies the load current for the 24 V power supply by means of its energy storage units. Maintenance-free capacitors are used as energy storage units.

  Signaling

  The LED on the device signals a supply voltage > 20.5 V.

  Особенности

  • Bridging of short-term power failures in the time range of seconds
  • Totally maintenance-free capacitors as energy storage
  • Short charging times
  • Parallel switching of several buffer modules possible
  • Fast mounting onto standard rail and simple wiring
