The newest generation of QUINT Power supplies gives control engineers improved configuration and diagnostics to ensure reliable power to the control system. Phoenix Contact has added near-field communications, real-time monitoring, coordinated surge protection, and a configurable DC output characteristic to the proven QUINT Power line.

With secured NFC, the QUINT POWER can be configured while still in the box. User-definable settings allow monitoring of real-time DC current, power, or voltage using a 4-20mA analog output. The QUINT Power supplies can also be made tamper-proof by locking out the push buttons on the front panel and creating a user-defined password. In addition, operating hours, DC Input voltage, overvoltage and temperature derating can also be monitored with dry contact outputs.

While QUINT Power supplies have always relied on metal-oxide varistors (MOVs) for transient protection, the new models add a gas-discharge tube (GDT) for coordinated protection.

The new generation continues the use of established QUINT features like Power Boost and Selective Fuse Breaking (SFB) technology. SFB technology delivers six times the rated current for up to 15 milliseconds to selectively trigger standard circuit breakers. The static boost with up to 125 percent of the rated current is available at all times, allowing the system to be conveniently expanded. For starting heavy loads, the dynamic boost with up to 200 percent of the rated current for up to five seconds is also available.


  • SFB technology selectively trips standard circuit breakers, loads connected in parallel continue working
  • Preventive function monitoring indicates critical operating states before errors occur
  • Signaling thresholds and characteristic curves that can be adjusted via NFC maximize system availability
  • Easy system expansion, thanks to static boost, starting of heavy loads, thanks to dynamic boost
  • High degree of immunity, thanks to integrated gas-filled surge arrester and mains failure bridging time of more than 20 milliseconds
