The QUINT POWER power supply is specifically designed for connection to high input voltages such as frequency converters. It can be simultaneously connected to the AC voltage and the DC intermediate circuit voltage of a converter. In the event of mains failure, the energy of the DC intermediate circuit continues to supply all connected 24 V loads without interruption. With all required safety certifications to support ITE (Information Technology Equipment), ruggedized packaging, extended operating temperatures, high peak load capabilities and high isolation voltages, the QUINT Industrial Power Supply is designed to meet the needs of your industrial application. The QUINT-PS/2AC/1DC/24DC/20 uses leading technologies to increase safety and reliability:

  • Preventive function monitoring warns against critical operating states before errors occur.
  • The static power reserve enables difficult loads to be started reliably with up to 1.25 times the nominal current (POWER BOOST).
  • Fast tripping of standard circuit breakers with up to six times the nominal current for 12 ms (SFB technology).

18 to 29.5 V DC Adjustable Output Voltage Range

Using the rotary potentiometer on the front face of the QUINT power supply, the output voltage can be optimally adjusted to meet specific application environment requirements. For example, you can easily adjust to compensate for a voltage drop caused by a long cable length.

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. With the QUINT Power Boost function a static boost will continuously provide up to 125% of the nominal current. 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.

Preventive function monitoring reports critical operating states before they occur

Power Boots Diagram

With a QUINT 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

Industrial operating temperature of -25°C to +70°C

Equipment found in traffic management, oil and gas pipelines, weather tracking, industrial and outdoor applications must function in temperatures that cannot be supported by a commercial power supplies. With an operating temperature of -25°C to +70°C the QUINT Industrial Power Supply is ideal for use with equipment subjected to harsh environments and severe temperatures.

High efficiency and low no load power consumption

Compared with other products on the market, the 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

QUINT Industrial Power Supply 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, the QUINT supplies up to 6 times the nominal current for 12 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.
