Arrancador suave para motores de inducción trifásico WEG

Soft-Starters are static starters that accelerate, decelerate and protect three-phase induction motors in power ratings from 2.2 to 1375 kW.

Features:

• 32 Bits RISC high performance microcontroller.
• Electronic motor protection.
• Removable Human Machine interface with double display (LED / LCD).
• Fully programmable control methods.
• Totally flexible torque control.
• Kick-start function for high break-away torque.
• Pump control function for intelligent control of pumping systems.
• Avoids water hammer in pumps.
• Current peaks limits on the power supply.
• Voltage drop limits during starting.
• Power supply voltage 220-575 V and 575-690 V.
• The control board power supply has EMC filter (94 to 253 Vac).
• Built-in bypass up 820 A, providing size reduction and saving.
• Back-up memory of motor protection I2t thermal image.
• Voltage and current unbalance protection.
• Over / under voltage and current protection.
• Input for motor PTC.
• Reduction of mechanical stress.
• Reduction of stress over couplings and transmission devices (gearboxes, sheaves, belts).
• Increases the lifetime of the motor and mechanical equipment of the driven machine.
• Easy operation, programming and maintenance via HMI.
• Simplified electrical installation.
• Oriented Start-up.
• Possibility for standard three leads or inside delta size cable connection (except 575-690 V models).
• All protections and function available for both types of connection (unique in the market).
• Serial or fieldbus communication errors protection.
• Operational environment up to 55 °C (without current reduction) for model range 10 A to 820 A and up to 40 °C (without current reduction) for model range 950 A to 1400 A.
