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.
