Lovato ADX Soft Starters
The Lovato ADX series reduced voltage soft starter with torque control provides the best control and protection for your three phase squirrel-cage motors. The range covers from 7.5kW to 630kW, and 208V to 690V.

Torque ramp provides smooth starting and stopping , and the in-built Boost Function ensures even the highest load torques can be started. The ADX's Dynamic Braking feature caters for applications that require a quick stop.

Feedback
Full monitoring of motor phase currents and voltages, consumed power, kWh metering and I/O status provides you with all relevant data.

Protection
Protection provided as standard with the ADX ensures your process reliability is maintained. This includes dual class motor thermal protection, locked rotor, underload, and current asymmetry. Integral bypass contactors drastically reduce heat dissipation resulting in smaller cabinets and significant cost savings on cabinet ventilation.

User Friendly
The ADX is full of features to make it easy to use. Combined with a realtime clock, the events log provides an extensive diagnostic tool. Comprehensive control connections and integral Modbus RTU communications make integrating the ADX into your process control seamless.

Accessories
Interfacing with the ADX is made simple through a wide range of accessories. Remote control and supervision is easily achieved using ADX software which provides a facility for easy commissioning, parameter storing and trending, with the capability of both direct connection to a PC and via a modem.
