The QUINT4-PS/1AC/24DC/5 Industrial Power Supply is rugged AC to DC and DC to DC Converter built to meet the high stability and efficiency expectations of industrial, machine automation and process control environments. It also feature the unique combination of preventive function monitoring and power reserve in an incredibly compact size. This Switching (switch mode) Power Supply ensures a regulated output voltage even in the event of voltage fluctuations in the power supply network. During parallel operation, and when connected to different phases, loads are reliably supplied even in the event of problems with the input voltage. With all required safety certifications to support ITE (Information Technology Equipment), ruggedized packaging, extended operating temperatures, high peak load capabilities and high isolation voltages, this QUINT Industrial Power Supply is designed to meet the need of your industrial application.

POWER BOOST: reliably start difficult loads


A high degree of flexibility is required to configure, optimize and expand large systems. To optimally adapt a system or machine to your requirements, a power reserve in the power supply unit is crucial. The QUINT4-PS/1AC/24DC/5 supplies up to 50% additional current without a voltage drop. This is useful when it is not possible to predict which loads will be switched on at the same time or high switch-on currents of capacitive loads have to be absorbed without voltage dips. With the QUINT Power Boost function a static boost will continuously provide up to 125% of the nominal current. In addition, you can use the dynamic boost to supply 200% of the nominal current for 5 seconds when starting up heavy loads.

Preventive function monitoring reports critical operating states before they occur

Preventive function monitoring report diagram

With the QUINT4-PS/1AC/24DC/5 Industrial Power Supply, the output voltage and output current are constantly monitored. Preventive function monitoring visualizes critical operating states and indicates them locally and remotely to the controller as follows:

  • Via LED
  • Via floating relay contact
  • Via active switching output

High efficiency and low no load power consumption

Compared with other products on the market, this QUINT Industrial Power Supply provides excellent energy savings. With a very low no load power consumption and high efficiency at nominal load, just a small amount of electrical energy is converted into undesired heat energy making these very ECO friendly power supplies.

SFB (Selective Fuse Breaking) Technology

SFB (Selective Fuse Breaking) diagram

SFB Technology can be used to quickly and reliably trip miniature circuit breakers and fuses connected on the secondary side. In the event of a short circuit on the secondary side, this QUINT supply up to 6 times the nominal current for 15 ms. Faulty current paths are switched off selectively, the fault is located, and important system parts remain in operation. Loads that are connected in parallel are still supplied with energy ensuring continued operation of these system parts.

  • Tripping circuit breakers: The circuit breaker is typically tripped by the high SFB current within 3 to 5 ms. As a result, any voltage dips for loads connected in parallel are avoided.
  • Tripping a fuse: Fuses are tripped by melting the predetermined breaking point inside the fuse capsule. The tripping characteristic of the fuse is described by the melting integral (I²t). A high current is crucial in order to achieve a very short tripping time.

Near Field Communication (NFC)

Near Field Communication (NFC) is a transmission standard for wireless and contactless data exchange at a close distance. With NFC, you can easily parameterize the QUINT4-PS/1AC/24DC/5 Power Supply settings such as define signaling thresholds for preventive function monitoring, adjust output voltage, and adapt the output characteristic curve to your specific requirements using a PC, mobile phone, or mobile terminal device. You can also save and send configuration profiles on your mobile terminal device. QUINT4-PS/1AC/24DC/5 Power NFC App on the Google Play Store
