Buffer module on the DIN rail

Buffer module

Configure your UPS system with a maintenance-free buffer module. Protect your application and bridge mains failures lasting up to several seconds. The buffer modules combine an electronic switch-over unit and maintenance-free, capacitor-based energy storage in the same housing. They are suitable for DIN rail mounting and save space thanks to their compact design.

QUINT CAP buffer modules with interface
Maintenance-free buffer modules
Intelligent protection with integrated interface

The QUINT CAP buffer modules with interface can be easily integrated into industrial networks. They buffer cyclic failures of up to several minutes and combine an electronic switchover unit and energy storage device in one housing.

These are the main features

  • Easy integration into industrial networks with freely selectable interface: PROFINET, EtherNet/IP and Modbus/TCP, EtherCAT, USB and Modbus/RTU
  • Long service life with maintenance-free double-layer capacitors
  • Reliable startup of high loads with static boost
  • Comprehensive signaling: Preventive function monitoring reports critical operating states before faults occur
  • Extension of the buffer time with parallel connection of up to four devices

These are the advantages

  • Long service life (+40°C): ≥20 years
  • Fast charging up to 10 A
  • Wide temperature range (start-up type tested -40°C): -25°C ... +60°C
  • Charge/discharge cycles: ≥500,000

QUINT CAP – long buffer times for mains failures

The maintenance-free QUINT CAP buffer module is ideal for cyclical failures lasting 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.

  • Double-layer capacitors
  • Buffer time of up to several minutes for 3.8 A to 20 A
  • Life expectancy (+20°C): ≥20 years
  • Charge/discharge cycles (+20°C): ≥500,000
  • Temperature range: -40°C … +60°C
  • Comprehensive signaling
  • Installation altitude up to 4,000 m

Your advantages

  • Maintenance-free with long service life
  • Space-saving, as the buffer module combines an electronic switchover unit and capacitor-based energy storage system in the same housing
  • Long buffer times with high memory capacity
  • Easy integration into industrial networks with freely selectable interface: PROFINET, EtherNet/IP™, and USB
  • Reliable startup of high loads with static boost
  • Simple system-specific settings can be made with the configuration tool
