ABB PS DH110 Soft Starter for Industrial Motors

Description

The ABB PS DH110 is a high-performance soft starter designed to provide smooth acceleration and deceleration for three-phase induction motors. By controlling the voltage ramp, it minimizes mechanical shock and electrical current peaks during startup and shutdown. This unit is ideal for applications where reliability and extended equipment life are critical.

FAQ

No, the PS series soft starters are designed for standard 'in-line' (3-wire) motor connections only. An 'inside-delta' (6-wire) connection would require a different type of soft starter rated for 1.73 times the motor's full load current.

No, the standard ABB PS series, including the PS DH110, does not have a built-in bypass contactor. For applications requiring a bypass function to increase efficiency and reduce heat after the motor is at full speed, an external bypass contactor must be installed and controlled separately.

The Torque Control feature is primarily used for optimizing the stopping of pumps. When enabled, it helps to eliminate the 'water hammer' effect by controlling the motor's deceleration torque, ensuring a smooth and gradual stop of the fluid flow.
