The company and Scientific-Manufacturing firm "EPRO" has operated for about seven years successfully in the Petersburg market, solving various problems in the field of electronic technology, connected with the use of static transformers.
Based on development work carried out by "EPRO", systems have been created for guaranteed supply, induction heating, regulated electrical gear, including electrical traction gear with alternating current for urban electrical transport.
This group offers itself as a bank of specialists many years experience in developing, planning, modifying and testing marine electronics products and as specialists who has been creating mobile rail units with electrical traction gear with alternating current for many years.
General Director Hosidov Zelman Kelmanovich. Chief Engineer Lerman Zachar Samoilovich. Head of Department Syrkin Boris Sazarevich.
The firm offers.
For the rolling stock of city electric transport a complete, assembled and junction-wide development, repair and supply of traction and auxiliary electrical equipment, based on applying transistorised transformers of constant force voltage to constant voltage of other levels, with monophase alternation and three-phase alternation of voltage at the required amplitudes and frequency.
For general industrial systems and systems of dual application transformers for regular electric supply with alternating current, for constant supply of essential parts, for induction heating systems, with precision parameters of output values; algorithms for governing transformers, protection of transformers and their load, organization of electromechanical characteristics of supply; services for undertaking expert work, for consultations and for teaching and apprenticing the personnel of the Purchaser.
Major results of the work of "EPRO": built, modified, tested and conducted test running of electrical traction gear with alternating current on an experimental six-axle articulated tram carriage with transport of passengers.
"EPRO" has developed, manufactured, modified and tested a range of transformers, designed for supplying motors for ventilators, compressors and pumps for various purposes with power ranging from a fraction to tens of kilowatts, as well as stabilisation of output paramenters.
The firm has developed, manufactured and tested precision sources of constant supply with a high quality form of output sinusoidal voltage - monophase with a power of 3 kWt and three-phase with a power of 9 kWt.
Opportunities and aspects of the work of the firm:
- publication of design documentation;
- manufacture and supply of examples;
- modification and testing of supplied examples at testing areas and sites;
- development and dissemination of algorithms for governing transformers, drawing up of required electromechanical characteristics, protection and diagnostics;
- expert and consultancy work;
- training the personnel of the Purchaser.
