Application Description With its small size, it can easily fit in place of existing soft starters, wye-delta starters, or across-the-line NEMA® and IEC starters. This feature allows easy upgrades to existing systems. The product is designed to be wired in the three-phase line feeding the three motor input leads as is done for normal across-the-line starting. The starter uses silicon controlled rectifiers (SCRs) to ramp the voltage to the motor, providing smooth acceleration and deceleration of the load. After the motor is started, the internal run bypass relay closes, resulting in the motor...

Reduced Voltage Motor Starters Solid-State Controllers Run bypass mode greatly reduces internal heating created by the power dissipation across the SCRs. The bypass relay directly connects the motor to the line and improves system efficiency by reducing internal power losses Less heat minimizes enclosure size and cooling requirements, and maximizes the life of all devices in the enclosure LED displays device status and provides fault indication Variable ramp times and voltage control (torque control) settings provide unlimited starting configurations, allowing for maximum application...
