QUINT ORING active redundancy module with MOSFET

Active redundancy modules

The QUINT S-ORING active redundancy module decouples supply networks with MOSFET and keeps cables separated up to the load. In combination with the new QUINT POWER power supply units, input voltage and the decoupling section are monitored continuously. The QUINT ORING active redundancy module features ACB (auto current balancing) technology. This balances the loads on power supplies equally, and therefore extends their service life.

QUINT S-ORING active redundancy module

QUINT S-ORING active redundancy module

QUINT SINGLE ORING active redundancy module

The QUINT S-ORING active redundancy module decouples with MOSFET and this provides for superior system availability and maximum operational safety. Supply networks are decoupled and lines are routed separately – consistently through to the load. In combination with the fourth generation of the QUINT POWER power supplies, the input voltage and decoupling section are monitored continuously. The Plus version and the VP version with protective circuit and overvoltage protection (OVP) protect sensitive loads. Overvoltages are limited to <28.8 V or <30 V respectively.

  • VP version > 30 V (QUINT4-S-ORING/12-24DC/1x40/VP)
  • Plus version > 28.8 V (QUINT4-S-ORING/12-24DC/1x40/+)

Your advantages

  • Consistent redundancy thanks to separate cable guidance up to the consumer
  • Preventive function monitoring, thanks to constant monitoring of the input voltage and decoupling section
  • Save energy by decoupling with MOSFET
  • Protection against overvoltages at the output (OVP) maximizes the operational safety
  • Protective coating with ATEX and IECEx approval for extreme environmental conditions
  • Active redundancy module is part of the COMPLETE line system

QUINT ORING active redundancy module

QUINT ORING active redundancy module with ACB Technology

The ACB Technology (Auto Current Balancing) of the QUINT ORING active redundancy module extends the service life of redundantly operated power supplies by evenly utilizing the power supply units.

The QUINT ORING modules with preventative function monitoring continuously monitor the input voltage, output current, and decoupling section in a system consisting of two QUINT POWER power supplies and one QUINT ORING. Any loss of redundancy is therefore indicated early on. Two positive output terminals ensure consistent redundancy through to the consumer. The installed MOSFETS reduce the power dissipation to the extent that energy savings of around 70 percent are achieved. Overvoltage protection (OVP) limits surge voltages to 32 V.

Your advantages

  • Consistent redundancy through to the consumer, with two positive output terminals
  • Service life doubled, thanks to uniform load distribution
  • Preventive function monitoring through constant monitoring of the input voltage, output current, and decoupling section
  • Energy savings of 70% thanks to the use of MOSFETs
  • Protection against overvoltages at the output (overvoltage protection) maximizes the operational safety

Double the service life, thanks to ACB Technology

As a result of asymmetries, the load is often supplied by just one power supply unit, while the other power supply unit runs in no-load operation. This results in a thermal load on the working power supply unit and therefore rapid aging.

The ACB technology of the QUINT ORING modules ensures a symmetrical loading of both power supplies. The input voltage difference between the power supplies is continuously determined and automatically compensated up to a deviation of 300 mV. The load current is therefore distributed symmetrically.

Thanks to the use of modern MOSFET technology, the resulting thermal load is reduced by up to 70%. This lower level of power dissipation ensures that all the control cabinet components stay cooler and the service life of devices in the redundant system is doubled.

Detect and avoid critical states

The QUINT ORING active redundancy module monitors the load current and generates a warning as soon as a set value is exceeded. If the user connects additional loads to a redundant power supply as part of a system extension, this can result in the loss of redundancy.

Two redundant power supplies each with 5 A nominal current supply a controller with the 5 A required. If an additional load of 3 A is connected, this can be supplied by the power supply's power reserve. The required current of 8 A is provided with no voltage dip. However, there is no longer any redundancy: If one of the two power supplies fails, the second device is no longer able to provide 8 A. The ORING modules immediately signal to the system operator that redundancy is no longer available. They detect critical operating states within the entire supply path and notify the operator in good time.
