Schneider Electric ATS48 (Altistart 48) -- soft starters for demanding industrial applications
The ATS48 series from Schneider Electric is a range of soft starters featuring the patented TCS (Torque Control System) technology. The six-thyristor bridge configuration of the Altistart 48 provides controlled acceleration and deceleration of three-phase squirrel-cage asynchronous motors rated from 4 to 900 kW. Our catalogue features 42 ATS48 models with nominal currents from 17 to 1200 A for 400 V and 690 V supply networks.
Key advantages of the ATS48 series
Unlike simpler soft starters such as the Schneider ATS22, the ATS48 series is designed for heavy-duty industrial applications and delivers:
- Torque Control System (TCS) -- smooth starting and stopping regardless of motor load, without speed feedback
- Six-thyristor bridge configuration -- control of all three phases for balanced and symmetrical starting
- Built-in motor thermal protection -- protection classes from 10 to 30 depending on operating conditions
- Integrated display terminal -- programming, adjustment and monitoring without additional equipment
- 4 discrete inputs, 2 discrete outputs, 3 relay outputs -- flexible integration with automation systems
ATS48 product lineup
The ATS48 range covers a wide power spectrum. Models with the Q suffix are designed for 400 V networks, while the Y suffix denotes 690 V versions. Below are representative models:
| Model | Rated current, A | Voltage, V | Typical application |
|---|---|---|---|
| ATS48D17Q | 17 | 400 | Small pumps and fans |
| ATS48D47Q | 47 | 400 | Conveyors, compressors |
| ATS48C11Q | 110 | 400 | Large ventilation systems |
| ATS48C32Q | 320 | 400 | Major pumping stations |
| ATS48M10Q | 1000 | 400 | Industrial compressor installations |
The full range includes models rated at 17, 22, 32, 38, 47, 62, 75, 88, 110, 140, 170, 210, 250, 320, 410, 480, 590, 660, 790, 1000 and 1200 A -- each available in both 400 V and 690 V versions.
How to choose an ATS48 model
When selecting an Altistart 48 soft starter, consider the following criteria:
- Motor rated current -- the primary selection parameter. The ATS48 rated current must be at least equal to the motor full-load current.
- Supply voltage -- Q models for 400 V networks (standard for most industrial facilities), Y models for 690 V networks (high-power drives, mining industry).
- Load type -- standard duty (class 10) is sufficient for pumps and fans, while conveyors and compressors may require heavy duty (class 20--30).
- Starts per hour -- affects the thermal protection class selection and potential need to upsize the unit.
