DS7 Series (2 phase Thyristor Control)
Soft Starter DS7
The DS7 is Eaton's solution for judder-free motor starts with power network protection. It is the perfect alternative to direct-on-line or star-delta motor starting. With the three phase motor currently the optimum drive for simple and cost effective machine and system building, the DS7 is the ideal solution.
DS7 – now up to 200 A
The 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. Additional benefits include extended services intervals and reducted operating costs.
230 – 480 V ±10 %, 50/60 Hz
24 V AC/DC / 110 – 230 V AC
4 – 32 A (1,5 – 15 kW at 400 V)
The reduction of peak-currents and the lower wear of the machine ensures that you get the following comparison between conventional solutions, Soft Starters and Frequency Inverters.
Motor voltage – soft start
Motor torque – reduced load
Motor current – damping current peaks
