EPCOS TDK

It features a user interface with a menu-driven display in plain text for maximum ease of operation. Straightforward symbols and alphanumeric displays in the language of the
country of use (nine languages) combine maximum ease of handling with convenient presentation of results.

Display of various grid parameters, storage of various values and a test run option make it easy to analyse errors and monitor the system.

An automatic initialization is available which will reduce the commissioning to a minimum.

Based on the well-proven MKP technology with stacked windings, DeltaCap™ capacitors are especially developed for LV-PFC applications in industrial installations. The cost-effective design offers a broad output range from 0.5 kvar to 33.0 kvar. The voltage range covers 230 V AC to 525 V AC.

TDK has been offering a comprehensive range of key components for Power Factor Correction (PFC) and Power Quality Solutions (PQS) for many years. The rapid development of industry and infrastructure resulted in the increased usage of power electronic loads which demands a highly dynamic response time for reactive power compensation. Conventional reactive power compensation only with passive components cannot fully meet these conditions, especially when the reactive power requirement is rapidly changing. EPCOS Static Var Generator (SVG) PQvar Series utilizes three levels inverter topology to provide real time response to reactive power requirements.

• New approach to power factor correction and load balancing
• Fast response time < 15 ms, with dynamic reaction time less than 50 µs
• Precise compensation after compensating the target power factor can reach a value of unity
• Capable of both inductive and capacitive compensation and will avoid under and over compensation issues
• Minimal loss, better energy efficiency, long-term safe and reliable operation
• Modular design, compact structure, small footprint, simple operation, easy maintenance

The TSM-LC for Dynamic PFC is a fast electronically controlled, self-observing thyristor switch for capacitive loads up to 50 kvar (380 / 400 VAC) which is capable to switch PFC capacitors within a few milliseconds as often and as long as required without abrasion. Triggering can be done by means of dynamic power factor controllers, programmable logic controllers (PLC) or directly out of the technologic process.

Features

• Component for the design of Dynamic PFC-systems in 380V and 400V-grids
• Automatically adapted by microprocessor to de-tuned and conventional capacitor branches (up to 14%); therefore optimization of the switching behavior.
• Available for 25 kvar and 50 kvar
• Monitoring of voltage, phase sequence, temperature; display of status via LED
• Switching without time lag
• No system perturbation caused by switching operations (no transients)
• No auxiliary supply needed
• Maintenance free
• Long operational life
• High switching speed
• No noise during switching
• Compact design ready for connection

Application

Dynamic (real time) PFC for fast processes, e.g.

• pressing
• welding machines
• elevators
• cranes
• wind turbines etc. with fast changing and high fluctuating loads
