QUINT ORING active redundancy modules feature ACB (auto current balancing) technology.
This means that your power supplies are utilized to an equal degree and their service life is therefore extended.

Your advantages

  • Service life of the redundant solution is doubled, thanks to uniform distribution of the load current
  • Save 70% energy – decoupling with MOSFETs instead of diodes
  • Consistent redundancy: using two positive output terminal blocks for wiring up to the load
  • Surge voltages are limited to 32 V thanks to OVP (Over Voltage Protection)
  • Early indication before redundancy is lost – by permanent monitoring of the load current for example

Detect and avoid critical states

Active redundancy modules for the most demanding requirements  

The threshold value for the load current can be selected.

A controller that requires 5 A is supplied by two redundant power supply units, each with a nominal current of 5 A. If another load with 3 A is connected, the power supplies easily supply 8 A, with no voltage dip, using the POWER BOOST power reserve. However, there is no more redundancy. If a power supply fails, the second cannot supply 8 A. This is why checking the load current is important. With QUINT ORING modules, the system operator immediately notices when there is no more redundancy. They detect critical operating states within the entire supply path and notify the operator in good time.

ACB technology doubles the service life

QUINT ORING with ACB technology  

Superior system availability, thanks to ACB technology

Applications with the highest requirements in terms of operational reliability, demand redundant power supply solutions, so the failure of a power supply unit does not result in system downtime. As a result of asymmetries, the load is often supplied by one power supply unit. This results in a thermal load on the working power supply unit and thereby faster aging. If the power supply unit is operated at half the nominal current, it remains significantly cooler.

The ACB technology of the QUINT ORING modules ensures symmetrical loading of the power supplies and thereby up to double the service life of the redundant system.
