MCC Overview
Altistart® 48 Soft Starts in Low Voltage Motor Control Centers
The Altistart 48 Motor Control Center (MCC) Soft Start product offer provides a pre-engineered, integrated package consisting of a combination disconnect and soft start controller for reduced voltage starting.
Features
- Custom
performance
– available as pre-engineered and built-to-order to provide optimal
performance to meet specific application requirements.
- Increased
functionality
– units integrate the advanced features of the Altistart 48 Soft
Start.
- Linear
torque control
– features patented Torque Control System (TCS) for both starting
and stopping conditions.
- Seismic
rating –
seismically qualified as defined in the International Code Counsel Evaluation
Service (ICC ES) Acceptance Criteria for Seismic Qualification Testing
of Nonstructural Components (AC156).
- Protective features – thermal motor protection by I2t calculation with phase loss detection and protection from excessive starts, with overload and underload protection for the machine.
Benefits
- Torque Control System
– The advanced functionality of the Altistart 48 Soft Start and
its patented Torque Control System develops only the torque needed to
accelerate the load. The starter provides a constant acceleration rate
that is independent of the motor load and controls machine torque during
both acceleration and deceleration. As with traditional voltage or current
limiting systems used by the competition, the motor torque changes according
to the speed and load, and acceleration / deceleration ramps are machine
dependent.
- Improved Line Frequency Tolerance
- Extended line frequency drift tolerance to cover both steady and transient
states.
- Increased Product Options
- Circuit Breaker or Fused Disconnect
- Input Isolation Contactor
- Reversing
- Integrated Full Voltage Bypass Starter
- AC1 or AC3 Duty Rated Contactors
- Severe Duty Rating
