Eaton DS7 Soft Starters
DS7 easily fits in place of existing soft starters, wye-delta starters or across-the-line NEMA and IEC starters. The voltage ramp start method provides a voltage ramp to the motor for constant torque increase. Users set initial voltage values and the duration of the ramp to full voltage conditions. Soft Stop allows for a controlled stopping of load when a stop-time greater than the coast-to-stop time is desired; for high friction loads where a sudden stop may cause system damage.
The Soft starter DS7 is ideal for pumps, fans and small conveyor applications. It is a fully integral element in the xStart system. The DS7 replaces the mechanical contactor and extends the "motor soft start" function.
Core features of the DS7 soft start controller
Run bypass mode greatly reduces internal heating created by the power dissipation across the SCRs
Bypass contactor 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 for maximum application flexibility
Manages peak starting torque to diminish mechanical system wear and damage
120 Vac or 24 Vdc control voltage available
Temperature monitoring sensors allow starter to trip in over/under temperature conditions, preventing device failure
Available with or without SmartWire-DT capability
