Pump & Motor Control Solution — Schneider Electric ATS48C32Y | Altistart 48 Series
Where This Product Is Used
The Schneider Electric ATS48C32Y is a high-power soft starter engineered for demanding industrial motor control applications where direct-on-line starting causes mechanical stress, voltage dips, or excessive inrush current. Typical deployment environments include:
- Water & Wastewater Treatment Plants — controlled ramp-up of centrifugal pumps eliminates water hammer and pipe stress in municipal and industrial water systems.
- HVAC Systems — smooth starting of large air-handling unit fans and chiller compressors reduces peak demand charges and extends belt/bearing life.
- Mining & Quarrying — belt conveyor drives and crusher motors benefit from torque-controlled acceleration, reducing mechanical shock on gearboxes and couplings.
- Oil & Gas Facilities — pipeline booster pumps and gas compressors require controlled starts to protect seals and prevent pressure surges.
- Marine & Offshore — generator-limited power systems where inrush current must be strictly managed during motor starting sequences.
- Cement & Aggregate Processing — high-inertia loads such as ball mills and rotary kilns where extended ramp times are required.
- Food & Beverage Processing — hygienic pump and mixer drives where smooth torque delivery prevents product spillage and equipment damage.

Why Engineers Specify This Model
- Internal Bypass Contactor — eliminates the need for an external bypass contactor, reducing panel space and wiring complexity. Once at full speed, the bypass engages and the SCRs carry zero current, minimizing heat dissipation.
- Torque Control Algorithm — unlike voltage-ramp-only starters, the ATS48 series uses a closed-loop torque control strategy, delivering consistent acceleration regardless of load variation — critical for pump and compressor applications.
- Soft Stop Function — programmable deceleration ramp prevents water hammer in pump systems without the cost of a variable frequency drive.
- Advanced Motor Protection — integrated phase loss, phase imbalance, overcurrent, undercurrent (dry-run), and thermal overload protection reduces the need for external relay modules.
- Wide Voltage Tolerance — 208–690 VAC range makes this unit globally deployable across North American (480V), European (400V), and Asian (660V) grid standards without hardware changes.
- Fieldbus Ready — native Modbus RTU port enables integration into SCADA, DCS, and PLC-based control architectures for remote monitoring and parameter adjustment.

Application-Specific FAQ
Q: Can the ATS48C32Y be used with a bypass contactor for energy saving?
A: The ATS48C32Y has an internal bypass contactor built in. Once the motor reaches full speed, the internal bypass engages automatically — no external bypass contactor is required, saving panel space and cost.
Q: Is this soft starter suitable for high-inertia loads like centrifuges or ball mills?
A: Yes. The ATS48 series supports extended ramp times up to 60 seconds and can be configured for Class 20 or Class 30 thermal protection to accommodate high-inertia starting cycles.
Q: Can I control the ATS48C32Y via Modbus from a Schneider M340 or M580 PLC?
A: Yes. The unit has a built-in Modbus RTU port (RJ45). It is fully compatible with Schneider Electric Unity Pro / EcoStruxure Control Expert environments using standard Modbus function codes.
Q: What is the difference between ATS48C32Y and ATS48C32Q?
A: The suffix letter denotes the control supply voltage. The Y variant accepts 110–230 VAC control supply; the Q variant is designed for 380–415 VAC control supply. Ensure your control circuit voltage matches before ordering.
Q: Does this unit require derating in high-altitude or high-ambient-temperature installations?
A: Yes. Above 1000m altitude or 40°C ambient, current derating applies per Schneider Electric’s ATS48 installation guide. Contact our technical team for site-specific derating calculations.
Q: Can Konmask.com provide the ATS48C32Y with a test report or factory certificate?
