## Summary description

PHOENIX CONTACT QUINT-BUFFER/24DC/20 buffer module (model 2866213) provides 20 W buffering for 24 V DC systems. Designed to maintain supply stability during short interruptions, it integrates with QUINT power systems to extend hold-up time and protect connected equipment. Suited for industrial control panels, automation and critical electronics requiring uninterrupted 24 V DC power.

## Long description

The PHOENIX CONTACT QUINT-BUFFER/24DC/20 is a maintenance-free capacitor-based buffer module designed to maintain 24 V DC supply to connected loads during brief mains interruptions. It provides buffered energy to extend hold-up time for automation equipment and control panels, integrating with QUINT power systems to ensure continuity of supply for 24 V consumers.
Advantages
The buffer uses a storage capacitor for maintenance-free energy buffering and includes an integrated diode to decouple loads, reducing costs. It features optimized power management and signaling plus an integrated timed shutdown function for controlled power-off. Compact dimensions and screw terminal connections allow easy installation in industrial switchgear.
Suitable for
Industrial control panels and automation systems
Protection of critical 24 V DC electronics during short mains interruptions
Applications requiring short-term hold-up time for sensors, PLCs and actuators

How to use
Mount the buffer module on a DIN rail or suitable panel location and connect the 24 V DC input and output using the screw terminals. Ensure the input voltage is within the specified range before commissioning. The unit operates automatically to supply buffered energy to the 24 V bus during short mains interruptions; monitor any signaling outputs from the associated power system for status and fault indications.
Usage recommendations
Use the QUINT-BUFFER/24DC/20 together with a compatible QUINT power supply and follow manufacturer installation instructions. Verify that connected loads and system wiring are rated for the maximum output current, and plan for longer backup times with battery-based UPS solutions if interruptions exceed the capacitor buffer’s hold-up time.
