Description

The ABB 3ASC25H285 DASD 105 Thyristor module is a solid-state power semiconductor device designed for heavy-duty motor speed and torque control in crane motion applications and heavy industrial machinery. Operating as a core power component within the ABB ASTAT crane motion control system, the unit regulates three-phase AC stator voltage and phase sequence via microprocessor-controlled phase-angle trigger pulses, delivering smooth, stepless motor acceleration, deceleration, and high-speed regenerative braking. The 3ASC25H285 DASD 105 connects directly to power distribution buses and interfaces seamlessly with DARA control system modules via optical links and dedicated pulse transformer connections.

Features

  • Designed for heavy-duty crane motions and harsh industrial environments.
  • Enables stepless electronic voltage and torque adjustment without requiring direction-reversal contactors.
  • Convection/fan-cooled compact assembly rated for panel installation.
  • Direct fiber-optic and pulse-transformer coupling to DARA control units for maximum noise immunity.
  • Integral internal system I/O board (DATX 100) with coated surface protection against conductive dust ingress.

Applications

  • Crane hoist motion control systems.
  • Crane travel motions (bridge and trolley drives).
  • Heavy industrial material handling machinery.
  • Speed and slip control of slip-ring induction motors.
