312Amp WEG SSW07 Reduced Voltage 220-575VAC Soft Starter SSW070312T5SH1Z

WEG SSW07 Voltage Reducing Soft-Starter is a high performance product that permits the start control of the three phase AC induction motors. Thus, it prevents mechanical shocks on the load and current peaks in the supply line. The SSW07 Voltage Reducing Soft Starters are static starting devices, designed for the acceleration, deceleration and protection of the three phase, electric induction motor through the control of the voltage applied to the motor. The SSW07, with DSP control (Digital Signal Processor), was designed to provide great performance on motor starts and stops with an excellent cost-benefit relationship. Because it is easy to set up, it simplifies start-up activities and daily operation. The SSW07 incorporates all electric motor protection classification and adapts to customer needs through its easy-to-install optional accessories. Such as, an optional keypad, a communication interface or a motor PTC input.

Features: 

• Significant reduction in mechanical stresses of the coupling and transmission devices (gearboxes, pulleys, gears, conveyors, etc.) during start.
• Increases motor and equipment lifetime due to the elimination of mechanical shock.
• Easy operation, setup, maintenance & installation.
• Operates in environments up to 55ºC (without derate for all models).
• Integral, electronic motor protection.
• Built-in by-pass minimizes power loss and heat dissipation in the thyristors, providing size reduction and contributing to energy savings.
• Built-in electronic thermal relay.
•  Avoids the “Water Hammer” in pumps.
• Limitation of voltage drop during start.
• Universal voltage (220 to 575 Vac).
• Switched type power supply with EMC filter for the control electronics (110 to 240 Vac).
• Thermal monitoring of both motor and soft starter.
