The Typact-TPD32 series of digital converters is a product of the ever growing technological demands of modern industrial systems, and draws on years of experience in the field of DC motor speed control. TPD32 is available in a wide range of motor power ratings and power supply types for solutions using both two quadrant and four quadrant operation. Designed to minimize user system requirements, the TPD32 offers a range of functions and dedicated application packages to cover the most complex requirements of modern industrial automation systems.
Analog DC Drives
TYPACT – TPy2/TPy3….1B,2B/4B
TYPACT – TPy2/TPy3…1B,2B/4B
Three-phase single and two quadrant armature converters.
* Supply: 1x 230V, 1x415V,3 x 415V, 3 x 500V, 3 x 660V
* Nominal currents: 20…4600A
* Protection degree: IP00
The power section consists of an internally controlled Graetz bridge for the power supply of medium and big DC motors with separate excitation. As for the field power supply the converter has a single-phase Graetz rectifier bridge supplied with an RC protection filter and a circuit with an excitation loss relay.
The three series, TPy3-415/480-…-2B, TPy3-500/600-…-2B and TPy3-660/800-…-2B are different only for the maximum power supply voltage on the power section and for a part of the regulation section connected via connector cable. Starting from the 110A size, the converters are forced-ventilated. The two quadrant functioning methods with a recovery braking and the three quadrant functioning methods with a reversible field controller (TPey2…4B) require the use of devices with the “+e” option. On the converter it is possible to put up to four “y” option cards (for “TPy..2B+e” a maximum of three) on the rear side of the regulation card with an internal connection to the converter via a flat cable and a FA… connector.
