Specific technical solutions together with the program of professional care will ensure the smooth operation of your devices. Our philosophy is not just to sell many inverters; our philosophy is to do challenging engineering projects with own products.
One of the biggest challenges for humanity in the third millennium is to solve the energy issues. Demand for energy will increase as long as demand for higher standards of human life will grow. Moving to renewable energy sources will become necessary for future generations and now we know that it is possible, therefore we have added solutions for renewable energy and other "green solutions" to our portfolio. We have built them on our rich experiences, on the latest scientific knowledge and our own research with fast application of the results to the practice. We provide customers with genuine quality products and services while taking active steps to the protection of the environment. All products are manufactured from quality components, nature-friendly, recyclable, with emphasis on the very long life span. Furthermore, VONSCH offers unbeatable service with nonstop technical support and a guarantee that the problem is resolved. Our environmentally-friendly solutions for the effective use of renewable energy sources are based on our own products such as:
Our mission is to contributie with our research, development and production to the ecological and cheaper methods of electricity production and optimal energy mix. Although the "green" solutions might seem expensive at first sight, the investment in the future is certainly worth of it.
For wind turbines VONSCH offers a device called WIND CONTROL 400, whose principle of operation is similar to MVE CONTROL . It adjusts the propeller speed independently and aically, on the principle of maximizing the energy produced. Benefits resulting from the use are similar to those of MVE CONTROL . WIND CONTROL is available in custom enclosure versions - the basic enclosure can contain other electrical equipment associated with operation of the plant. Power of the generators can be up to 1.4 MW and a standard induction motor can be used as generator. WIND CONTROL can be used to for off-grid power, but in these types of power plants the accumulation of energy needed to start the system and for excitation of the generator or a self-exciting generator must be used.
For horizontal wheels directly placed in the river, the production of energy without devices like MVE CONTROL is impossible. For example, speed of the water in Danube varies from 1.5 to 2.5 m/s, so this ratio must be adjusted to the orbital speed of a water wheel - generator. Excellent results were obtained when MVE CONTROL was used with vertical water wheel motors, which controlled the wheel speed (generator) to operate the plant even at low flow rates and water speeds, when the classical solutions with a generator connected directly to the grid cannot be used.
All these adaptations by MVE CONTROL are performed by maximization of power - it aically adjusts speed of the generator to the speed and "energy" of water and thus it maximizes the power of MVE CONTROL .
Supply of electricity to the grid is achieved by the control of the regenerative inverter, which also includes a network of independent circuits for the work of protections (current, voltage and frequency). Above the threshold values of output current, frequency and power parameters of the grid, MVE CONTROL is disconnected from the grid by opening the input contactor device. MVE CONTROL produces only active power - power factor is equal to 1.
MVE CONTROL is available in custom enclosure versions - the basic enclosure can contain other electrical equipment associated with operation of the plant. Power of the generators can be up to 1.4 MW and a standard induction motor can be used as generator.

Our philosophy is not just to sell many inverters; our philosophy is to do challenging engineering projects with our electric drives. Our purpose is to create individual solutions for each customer.
VONSCH performs two main ranges in custom development solutions:Please, do not hesitate to contact our sales department for more information.
VONSCH provides unrivaled professional comprehensive after-sales service for the entire range of our products. High-quality componentsof our products and 72 hours of testing of every product on the real load reduce the number of service calls to a minimum. The warranty period for each product are longer than defined by the law (25 months) and ordering preventive examinations or signing a service contract or program of comprehensive care, the warranty period is adequately extended. Our goal is the satisfied customer.
Nonstop number +421 905 253 188 - useful technical advice and prompt service is provided 24 hours a day.
Warranty repair is done either by the services agreement (where the repair can be arranged within 24 hours or as soon as possible), in agreement with the customer. Usually up to 3 days. Service by VONSCH is not only about 'traditional' arrival to the customer, which says nothing about the repairs, but full elimination of defects, since the service department has specialists that are equipped with all the spare parts and the know how. Warranty repair method is described in the documentation of products - lower power products should be delivered to VONSCH site, products of higher power will be repaired by our technician at customers site.
Post warranty service is just as fast, high quality and available as the warranty service. Several options are offered to the customer and free of charge advice is still provided, because the initial cause of the failure is very often in the connected devices or machines, and not in the product, which only indicates the error.
Preventive examinations and prophylactic service is done in agreement with the customer on the basis of a service contract or a contract for preventive inspections at agreed intervals.
In agreement with the client we offer training service for our devices, but we are able to train your personnel in a broader context.
We know that our service is our strength and we are proud of it.
The professional care about electric drives program is a service of complete maintaining and servicing of all brands of electric drives by VONSCH, in companies not engaged in electric drives, but where the drives are one of the tools for achieving strategic goals. Our experts provide inspection of the drives and prepare complete plan of care and determine the overall reliability of the system for every frequency converter. The output of the inspection is a document describing overall state of electric drives, including an overview of the drives and the grouping of the drives according the overall reliability. For these groups we prepare a timetable for next inspections and a list of recommended spare parts. Service history and records of inspection , together with measured data are stored and evaluated by our special database software.
