Soft Start - Altistart 48
Multi-Featured Altistart 48 Softstart
Part of Altivar
A full-featured soft start designed for 3-phase motors rated 17 to 1200 A, 3 to 1200 hp.
The Altistart™ 48 soft start features a patented advanced motor control algorithm called TCS or Torque Control System. Without speed feedback, the Altistart™ 48 soft start provides constant starting and stopping rates independent of motor loading, just like a more expensive AC drive. Setting the new industry standard for soft starts, the Altistart™ 48 controls the applied motor torque, making it ideal for a wider variety of applications than a traditional voltage ramp soft start with the current limit. In pumping applications, the Altistart™ 48 with TCS eliminates the long start and stop times, the hydraulic transients and slamming of check valves associated with "pump version" voltage ramp soft starts.
Ease of selection
Every ATS 48 soft start model is rated for all North American industrial and commercial voltages — 208, 240, 480, and 600V. It is available in 21 power ratings from 17 to 1200 amps and is available for every standard motor rating up to 1000 HP at 460 VAC. No oversizing is required. Product selection comes down to a simple selection of motor horsepower and duty cycle.
- 2 - 400 HP @ 208 VAC
- 3 - 450HP @ 230 VAC
- 7.5 - 1000 HP @ 460 VAC
- 10 - 1200 HP @ 575 VAC
