Product overview

Phoenix Contact QUINT4-PS/3AC/24DC/20, item number 2904622, is a din-rail power supply designed for high-availability control power. Its three-phase AC input architecture and 24 V DC / 20 A nominal output suit industrial control and automation power applications.

Use the complete type designation and item number when preparing a replacement. Selection must also confirm the connected load, startup current, protective devices, cabinet temperature, wiring terminals and required power reserve and output characteristic.

COMMON APPLICATIONS

Installed-system context

  • PLC, I/O and HMI control cabinets
  • Industrial networking and communication equipment
  • Machine, process and production-line DC loads
  • MRO replacement and power-system expansion

Tell us the controller, communication network and installed panel details. That context helps prevent a visually similar but incompatible replacement.
