Industrial Rectifier Systems

Rectifier systems and DC/DC converters

In many industry sectors, the electrical consumers used must be protected against the failure of the public grid by means of a backup power supply. For this purpose, rectifier devices with batteries connected in parallel have been used for many years.

Rectifier series designed for building reliable industrial power supplies: ADC Modular, TEBECHOP SE, THYROTRONIC, Rectifier NPP

Rectifier system ADC modular

The ADC modular series are highly efficient modular rectifiers that are particularly suitable for industrial use but also for the power supply of telecommunications systems. Together with lead or NiCd batteries connected in parallel, these rectifiers can be expanded to battery-supported backup power supplies.

Features of this rectifier series:

  • n+1 redundancy
  • Performance range: 300W to 2400W
  • Wide range input: 93V - 264V without derating
  • suitable for all common output voltages: 12 V, 24 V, 48 V, 60 V, 108 – 110 V, 216 – 220 V

Industrial rectifier THYROTRONIC

The THYROTRONIC industrial rectifier series is particularly convenient to use with battery-supported DC power supplies and, in addition to great reliability, offers a comprehensive signaling and monitoring concept.
Designed as an industrial power supply, these robust monoblock rectifier systems work with an electronically controlled output characteristic (IU characteristic according to DIN 41773).

Typical areas of application for these thyristor-controlled backup power supplies are:

Nuclear Plant Power Supply

Electronically controlled rectifier systems, in conjunction with the appropriate lead or NiCd batteries, form secure power supply systems that supply vital nuclear power plant consumers with electricity both when the grid is available and in the event of a grid failure.

These include:

  • the power plant control technology
  • Signalling, control and protection electronics
  • Telemetry and remote control technology
  • DC and AC motors
  • Magnetic valves

These BENNING rectifiers can be used for power supply in conventional coal, gas or water power plants as well as in nuclear power plants.

Industrial Inverter Systems

Inverters for safe industrial power supplies

Irregularities in the public supply network cannot be prevented due to the feedback effects of large consumers being switching on or off at peak consumption times and due to lightning strikes. Static inverters are increasingly being used to supply loads that require AC voltage that is unaffected by disruptions in the public grid, e.g. for power supply of:

Inverter series: INVERTRONIC, INVERTRONIC compact, INVERTRONIC modular, KKW Inverters

Inverter single and three phase

With these industrial inverters, very robust single and three-phase IGBT inverter systems (power range 10 kVA - 200 kVA) are available for tough industrial applications, for example as:

These inverters are connected to battery-backed DC grids and reliably supply critical loads with good quality power. The existing battery and rectifier infrastructure can remain in use.

Modular 19" inverters

With the INVERTRONIC compact inverter series, BENNING offers safe and cost-efficient, single-phase, modular inverter systems. In combination with the TEBECHOP SE modular rectifier systems, the final product is a flexible, adaptable and cost-efficient platform for setting up complete battery-supported backup power supplies with maximum availability.

These industrial power supplies are characterised by:

  • n+1 redundancy
  • autonomous inverter modules (hot plug)
  • extensive reporting and monitoring functions
  • EUE and service bypass as separate hot-plug modules
  • galvanic isolation

Three-phase 19" inverters

Compared to three-phase monoblock systems, INVERTRONIC modular inverters have a lower volume and weight. With n+1 redundancy, the parallel connection of the inverter modules results in power supply systems with maximum availability and a power range of 10 kVA – 180 kVA.

Advantages of these inverters when setting up industrial power supplies:

  • Easily scalable system performance
  • each 19" inverter module has its own electronic switching device (SBS)
  • Short MTTR (Mean Time to Repair)
  • Highest availability through n+1 redundancy
  • highly energy efficient due to good system efficiency factor even in the partial load range
  • lower system volume and weight reduce the required space and simplify transport and installation of the system

Hybrid UPS energy storage systems for industrial use

Bye-bye Blackout: Energy storage with EMS and UPS function

UPS-enabled storage systems offer economic efficiency and fast payback combined with safety for the critical load.

The critical loads are protected from mains disturbances by the UPS. At the same time, the system takes on load management tasks in conjunction with the "on-board" energy management system (EMS) and can therefore generate a high additional financial benefit compared to systems without a storage function.

The ENERTRONIC modular storage combines energy storage, UPS and energy management system (EMS). It can be individually configured, increases efficiency, reduces your operating costs and maximises security of supply.

Advantages of this UPS energy storage system:

  • Stores PV energy and uses it flexibly
  • Grid stabilisation through load balancing (peak-shaving) and primary control power
  • Quick charge booster with the same mains connection value
  • Black start and isolated operability
  • Reduces energy and operating costs

Modernisation or retrofitting is worthwhile, e.g. as part of a retrofit of existing UPS or storage systems (lead/Li-Ion batteries).

This is good news for all operators of ENERTRONIC modular SE UPS systems, as these systems can make full use of the energy storage functions as part of an upgrade.
