Industrial UPS

Static uninterruptible power supplies (also known as UPS systems) are for many applications indispensable today. Statistics show that in Germany on average between two and four extended AC mains failures and more than one hundred short interruptions in the range of milliseconds every year. Systems failures caused by these interruptions can lead to long downtime and data loss. Industrial UPS nominal power up to 200kVA 1~ or up to 500kVA 3~.

General Data

Our UPS are equipped with a coloured TFT Touchscreen-Display
and concists of the following components:

  • Rectifier (backfeed type for 100% battery test)
  • Battery (Eneregystorage)
  • Inverter
  • Electronic mains bypass
  • Service-bypass

Classification according to EN/IEC 62040-3: class VFI-SS-111

The UPS is built of discrete control and supervision boards (plug in modules with front signalling), each control and supervision board
(A2-A4) consists of its own analog control and microprocessor supervision.

The modular design offers an eminent advantage in time and cost in case of service or maintenance.

The transistor rectifier (sinusoidal input current, lambda > 0,99) is designed for the connection on
a three phase mains, for the supply of the inverter at rated load and simultaneously for charging the
battery. The rectifier has an IU-characteristic with adjustable current limitation.

The following battery types are aviable: low maintenance lead-acid batteries, maintenance free,
sealed lead-acid batteries or NiCd-batteries. The batteries are installed on racks or in cabinets.

Separate inputs for rectifier and bypass supply are provided.

UPS systems protect against

  • Short-duration interruptions
  • AC mains failure
  • Voltage variations
  • Superimposed interference voltages
  • Frequency variations
  • AC mains voltage waveform distorion

Our UPS protects your investments and supplies a save power to your resources at any time.

Decades of experience in railway signalling, telecom, power plants, hospitals and all kind of industrial applications stand for our high quality and availability.
