Engineered for industrial power reliability, the Phoenix Contact QUINT4-BUFFER/24DC/20 (2907913) is a maintenance-free capacitor-based buffer module that safeguards 24 V DC control circuits during brief voltage dips. Part of the QUINT BUFFER range, it installs on DIN rail and includes the preassembled UTA 107 universal rail adapter for rapid integration in control panels and machine systems.
Operating from 22.5 to 30 V DC, the module delivers a buffered 24 V DC up to 20 A; with a 0.2 s hold-up at 20 A it bridges micro-outages without batteries while achieving >98% efficiency when the energy buffer is charged. An active transistor status output and green Ready LED provide clear diagnostics, while 500 V isolation and a robust metal IP20 housing ensure dependable performance from -25 to +70 °C with derating above 40 °C. Conformity with EN 61000-6-2/-6-3 and the EMC/Low Voltage Directives, plus suitability per UL ANSI/ISA 12.12.01 Class I, Division 2, make it a strong fit for demanding industrial environments.
Whether protecting PLCs, I/O, sensors, or drives, this buffer module helps maximize uptime, simplify maintenance, and extend the life of your 24 V DC bus, and for added peace of mind in critical applications it is supplied with a 1-year warranty.
