This manual describes the installation and operation of the DXT Series 39-1250A Digital Solid State Soft Starter.
The DXT Series is a high-end digitally programmable solid state reduced voltage soft starter designed for three-phase AC induction or synchronous motors. It provides stepless soft starting to protect mechanical components from excessive torque stress and electrical systems from high inrush currents. The unit features advanced motor and load protection, including retentive thermal memory, dynamic reset capacity, and true thermal modeling, all built-in as standard features.
