Protect your application using our buffer modules for mains failures lasting for up to several minutes. The buffer module stores the energy required to bridge mains failures in maintenance-free capacitors. They are also suitable for cyclical failures.

Your advantages

  • Compact design saves space
  • QUINT CAP: maintenance-free with a long service life
  • Flexible thanks to fixed or variable activation thresholds
  • Convenient shutdown of PCs with the QUINT CAP
  • Longer buffer times with double-layer capacitors with the QUINT CAP

QUINT CAP – long buffer times for mains failures

QUINT CAP buffer module  

QUINT CAP buffer module for cyclic failures lasting for up to several minutes

The maintenance-free QUINT CAP buffer module is ideal for cyclical failures lasting for up to several minutes. Depending on the application, buffer modules are available with 1 kJ, 4 kJ, 8 kJ, and even 16 kJ, with or without communication interface.

  • Maintenance-free with a long service life.
  • Long buffer times with high memory capacity.
  • Space-saving: The buffer module combines an electronic switch-over unit and an energy storage system in a single housing.
  • Easy integration into industrial networks with a free choice of interface: PROFINET, EtherNet/IP™, or USB.
  • Reliable startup of high loads with static boost.
  • Simple system-related settings with the configuration tool.


QUINT BUFFER – compact buffer modules for failures lasting for up to several seconds

QUINT BUFFER buffer module  

QUINT BUFFER buffer module bridges failures lasting for up to several seconds

The QUINT BUFFER buffer module is compact and bridges mains failures lasting for up to several seconds.

  • Easy handling, as the capacitor-based energy storage makes it maintenance-free.
  • The compact design saves space.
  • Adjustable activation thresholds: auto mode is optimized for QUINT POWER power supplies. However, the buffer module can also be set manually – for applications involving transformers or in the case of long cables.
