Family of static analog converters
The Techdrive series of static converters (Analog Technology Thyristor Variable Speed DC Drive) bidirectional, 4-quadrant, regenerative, are designed to control the armature with variable voltage of DC motors in both directions.
They are able to provide voltages and currents of both polarities and can receive energy from the load and introduce it to the network.
Converters in this series cover a wide range of applications in different industries and the range of powers extends from a few Kw to approximately 750 Kw.
They are characterised by their circuit simplicity, application versatility, reduced size and both static and dynamic performance.
The use of power devices (SCR) with pack and disc modules, enabled an effective optimization of various sizes; the choice, however, of control circuits with highly integrated functions, has resulted in a decidedly cutting edge product, easy to use, with constant performance and high reliability.
Regulation and control circuits are galvanically isolated from power circuits, while the interface to and from the plant, is accomplished via reed relays which, being fed with autonomous voltage, give the converter a high immunity against disturbances. External commands can come from voltage free contacts or directly from the PLC.
