Lovato Electric ADXL0045600 Soft Starter 45A 22kW/400V 30kW/600V with Integrated Bypass and 100-240V AC Control Supply

The Lovato Electric ADXL0045600 is a professional-grade soft starter engineered to provide controlled acceleration and deceleration for three-phase induction motors. By managing the voltage supplied to the motor during startup, this device effectively minimizes mechanical stress on drive components and reduces high inrush currents that can destabilize electrical networks. With a rated operational current of 45A, it is optimized for motors up to 22kW at 400V or 30kW at 600V, ensuring versatile performance across various industrial environments.

Advantages

This soft starter stands out due to its integrated bypass contactor, which significantly enhances energy efficiency by eliminating power losses across the internal semiconductors once the motor reaches full speed. This design feature also minimizes heat generation within the control cabinet, extending the lifespan of the device and surrounding components. The wide-range 100-240V AC control supply voltage provides flexibility in installation, allowing the unit to be integrated into diverse control systems without the need for additional power supply modules.

Suitable for

• Industrial conveyor systems requiring smooth start-up to prevent product damage.
• Pumping stations where water hammer effects must be mitigated.
• Fan and blower applications to reduce mechanical wear on belts and bearings.
• Compressor units needing controlled torque during the acceleration phase.

When it may not be suitable

This device is not intended for applications requiring frequent reversing of the motor direction or high-frequency start-stop cycles, as soft starters are primarily designed for controlled acceleration rather than speed regulation. It is also not suitable for single-phase motor control or applications where variable speed control is necessary during normal operation.

Key specifications

• Rated operational current: 45A
• Power rating: 22kW at 400V and 30kW at 600V
• Control supply voltage: 100-240V AC
• Integrated bypass contactor
• Three-phase motor control

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The device must be mounted vertically in a clean, dry, and well-ventilated enclosure to ensure proper heat dissipation. After mounting, connect the three-phase power supply to the input terminals and the motor leads to the output terminals. The control supply voltage should be wired to the designated terminals, ensuring the correct voltage range is applied. Once wired, configure the acceleration and deceleration parameters via the interface to match the specific requirements of the connected motor load.

What to consider before purchase

• Verify that the motor's full-load current does not exceed the 45A rating of the soft starter.
• Ensure the available control voltage matches the 100-240V AC specification.
• Check the physical dimensions of the control cabinet to ensure adequate space for cooling.
• Confirm the application does not require variable speed control, which would necessitate a variable frequency drive instead.

Usage recommendations

Regularly inspect the terminal connections for tightness and ensure that the ventilation paths remain clear of dust or debris to maintain optimal thermal performance and operational reliability.
