Consumer voltage
keep constant
Die Batterie ist nicht nur ein optimaler Energiespeicher, der die Versorgung der Verbraucher bei Netzausfall übernimmt, sondern sie hilft auch beim schnellen Auslösen der Sicherungen.
Ebenso übernimmt sie Dämpfungseigenschaften, jedoch hat sie einen erheblichen Nachteil: Der Spannungsverlauf (vom ungeladenen Zustand von z.B. 1,8 V/Zelle Endladeschlussspannung bis zur Starkladespannung 2,35 V/Zelle, z.B. bei Bleibatterien) kann bei vielen Verbrauchern Schäden oder Funktionsstörungen hervorrufen. Eine erhöhte Spannung im Normalbetrieb kann die Lebenserwartung der Verbraucher erheblich reduzieren oder sie sogar zerstören. Eine Unterspannung kann zu Fehlfunktionen führen. Speziell hierfür wurde der Hochsetzsteller (Umrichter) entwickelt, der die Verbraucherspannung von 1,75 V/Zelle (1,0 V bei NiCd) auf 2,25 V/Zelle (1,42 V bei NiCd) konstant hält. Dieser ist für DC 24V / 48V / 60V / 110V und 220V oder auf spezifische Kundenanforderungen ausgelegt.
Merkmale des Hochsetzstellers
-
Konstante Verbraucherspannung +/- 1% bei Blei- und NiCd-Batterien
-
Lineare Einstellung der Ausgangsspannung
-
Eigenüberwachung
-
Geringere Zellenzahl (durch tiefere Entladeschlussspannung)
-
Erhöhung des Verbraucherstromes durch Parallelschaltung möglich
-
kompakte Bauweise (19“-Technik)
-
Bei Ausfall des Gerätes übernimmt ein Bypass die trägheitslose Versorgung der Verbraucher
-
Trotz des hohen Spannungsgangs (besonders bei Anlagen mit NiCd-Batterien), wird durch den Hochsetzsteller eine konstante Verbraucherspannung realisiert.

As a 19'' device or
Standalone unit available
Custom-made inverter systems according to your requirements, depending on power output, as a 19'' device or floor-standing unit with or without bypass system.
Static inverters serve as uninterruptible power supplies (UPS) to bridge short-term interruptions, power outages, and voltage or frequency fluctuations. Inverters reliably supply AC loads, primarily in industrial and railway sectors. This makes them an ideal preventative measure against power disturbances in data processing, automation, and control technology.
The maximum available inverter output is 500 kVA (3~) or 200 kVA (1~). Inverter plug-in modules are available for lower outputs.
The devices can be designed according to your requirements and performance needs (e.g. start-up currents, smoke extraction fans).

Kondensatorbank und/oder Bypass für DC/DC-Wandlersysteme
Gerade die sichere Auslösung von Sicherungselementen bereitet aufgrund der begrenzten Ausgangsleistung der DC/DC-Wandler erhebliche Schwierigkeiten – diesem Problem begegnet man meist mit einer Kondensatorbank. Die dort eingesetzten Elektrolytkondensatoren trocknen jedoch mit der Zeit aus, wodurch die Sicherungsauslösung nach einigen Jahren nicht mehr gewährleistet werden kann. Hierfür haben wir ein System (Bypass) entwickelt, mit dem wir die Kurzschlussenergie der übergeordneten Batterie nutzen.

Extension of autonomy periods
The increasing demands on our power grid due to renewable energies present grid operators with major challenges. Modern battery systems or fuel cells are becoming increasingly important for extending the operating time of battery systems or as a replacement for diesel generators, thus ensuring a reliable power supply.
Fuel cell systems
Fuel cells can also be used for reconversion to electricity in a wide variety of applications. When selecting, designing, and planning a fuel cell power supply in conjunction with battery systems, factors such as environmental friendliness, flexibility (power increase), maintenance costs, and operational reliability must be considered.
We can implement the complete systems (including electrolyzer) for you with partners.
Redox flow storage
Redox flow batteries utilize liquid storage media for energy storage (vanadium-ion batteries). This eliminates crucial aging mechanisms, enabling more than 15,000 charge and discharge cycles. With minimal maintenance, redox flow batteries have a lifespan of approximately 20 years. Their low environmental impact, high safety (explosion-proof and non-flammable), and reduced complexity and costs make this storage technology an attractive option.
Lithium-ion storage
Lithium-ion batteries generate their electromotive force through the movement of lithium ions. During charging, positively charged lithium ions migrate through an electrolyte from the positive to the negative electrode, while the charging current supplies electrons via the external circuit. The advantages of these energy storage devices include high energy density, no memory effect, and low self-discharge. However, improper handling poses a fire hazard.
