JST frequency converter - 1

www.jovyatlas.de www.jovyatlas.de www.jovyatlas.de Product Range Special Devices Frequency Converter JST Conversion of mains frequency into frequencies needed by customers Static Frequency Converter Type JST single-phase, three-phase JOVYATLAS manufactures frequency converters of type JST for power ranges from 10 to 20 kVA with single phase output and for power ranges from 10 to 600 kVA with three phase output. As a standard product, we offer the systems JST with frequencies of 50 Hz and 60 Hz. Frequency converters of the JST-series offer the optimal solution for the transformation of the mains frequency into a frequency desired by the customer. Low operating costs, compact design and high efficiency are characteristical for these systems. A comfortable monitoring and diagnostic system provides every necessary information about the operating status of the system. The clearly arranged control panel makes it easy to operate the systems and offers a simple adjustment of the displays and operating conditions via a menu-driven display. By a simple text display the measured values, alarm and status messages are displayed on LCD. The robust mechanical design enables use even under difficult operating conditions. In addition to an excellent sine wave the UPC systems from JOVYATLAS have an optimal control behavior, even at a 100% load change. The frequency of the series JST are constructed in a service-friendly way: all main components are accessible from the front panel with a few simple steps. The intelligent control system with an integrated microprocessor and the latest digital technology enable early error detection and high interference safety. The IGBT technology of the final stages provides a high plant efficiency of 92% - 96%. Frequency converters of the series JST have a 6-pulse rectifier bridge with a switch-on peak limiter and an LC filtering as standard. A PFC -rectifier is optionally available for controlling module. The excellent single-phase voltage regulation ensures even under extreme unbalanced load the full proper functioning of the device. The systems are equipped with an RS-232 interface for monitoring and an RS-485 interface for parallel remote display. Of course, the frequency converters of the JST series are meeting Europe‘s current standards for system reactions, RFI and electromagnetic compatibility. The frequency converters JST are systems with true online double conversion technology. For sure we would be happy to modify the systems of the type JST customized and work out an individual tailored offer to the specific needs of our clients. We provide a variety of options, for example parallel redundancy of equipment, relay board with four standard reports, custom reports on the relay card, remote display, higher protection classes, customized cabinet design etc.. The static frequency converter series FU JST are often used in testing laboratories: the possibility of variable settings, corresponding to the individual (laboratory) needed output voltage and frequency, enables highly flexible and effective work.
