Emotron TSA Soft Starters

The Emotron TSA provides controlled starting and stopping for three-phase motors in pumps, fans, compressors and conveyors. It helps reduce starting current and mechanical stress in applications that run at a fixed speed.

Control and protection for your process

• Three-phase torque control: controls motor torque during starting for smooth acceleration.
• Controlled pump stops: torque-controlled stopping helps reduce water hammer.
• Load monitoring: detects overload and underload conditions to help protect the driven equipment.
• Motor protection: built-in electronic motor overload protection and a thermistor input support motor temperature monitoring.
• Easy setup: a multilingual control panel supports parameter copying between units.

Selecting a TSA soft starter

The TSA range covers rated currents from 16 to 960 A, with three-phase supply versions for 200–525 V and 200–690 V. Units have IP20 protection for installation in a suitable enclosure. Communications and additional I/O are available as options.

To help select the right model for your starting duty, provide:

• The supply voltage, motor nameplate current and motor power.
• The application, starting load, required starting time and number of starts per hour.
• The stopping requirements, including any need for controlled pump stopping.
• The ambient temperature, installation altitude, enclosure and available mounting space.
• The control supply, motor temperature sensors, control signals and network connections required.

TSA soft starter documentation

For an existing installation, record the full soft starter type code and software version. Use the matching TSA instruction manual when checking parameters, terminals or option compatibility.

Frequently asked questions

What applications suit a TSA?

The TSA suits applications such as pumps, fans, compressors and conveyors that need controlled motor starting and stopping. Selection depends on the motor current, load and starting duty.

Does a TSA provide variable speed control?

A TSA soft starter controls motor starting and stopping; it does not provide continuous variable speed control during normal operation. If your process needs speed adjustment to match flow or pressure demand, consider an Emotron FDU variable frequency drive.

What information is needed for a replacement?

Send a photo of the existing soft starter label, the motor nameplate details and a description of the application, starting duty and control connections. This helps identify a suitable replacement.
