ADXNB series soft starters – Basic version

The ADXNB series from Lovato provides a straightforward and cost-effective soft starting solution for standard motor control applications. Designed for simplicity and ease of use, these starters are configured using only three front panel potentiometers, enabling fast setup without specialized tools or software.

Key adjustable parameters include initial voltage step (30–80% of line voltage), acceleration ramp time (1–20 seconds), and deceleration ramp time (0–20 seconds). With external overload protection required, the ADXNB is ideal for motors in pumps, fans, conveyors, and compressors where basic ramping and deceleration are sufficient. Its minimal design ensures ease of installation and high adaptability across varied systems.

ADXT... series - Advanced heavy-duty soft starters (three-phase control)

ADXT... soft starters for applications requiring high performance, reliability and robustness. Mainly used for control of heavy loads due to high torque availability during starting, overcoming the inertia of
applications such as crushers, fans, vertical/inclined conveyors, screw compressors etc.


The integrated or internal bypass contactor disabling the thyristors once motor starting is completed,
reducing energy consumption, generated heating and power dissipation.
• Auxiliary supply voltage 110...120 / 220...240 VAC
• Rated operational voltage 380...690 VAC


Advanced features:
- Various motor starting modes / Emergency mode: Running of the motor ignoring alarms
- Power Through function: allow starting with a damaged thyristor (2-phase control)
- Scheduled start: timer & clock modes, based on ADXT RTC
- Control of breaking/reversing contactors


ADXT soft starters can be installed with traditional in-line connection or inside delta connection
(six-wire connection) with thyristors connected in series to each motor winding. In this configuration, requiring
six-wire motors, the soft starter is only crossed by the phase current, which is significantly lower than the line current.


This permits the use of a smaller starter, resulting in cost savings, and simplifies the replacement
of star-delta starters since the existing wiring is retained
