Eaton's low voltage soft starter is compact and multifunctional, making installation and programming easy.
Main features of DS7: - Smooth and asymmetrical motor control without using DC components - Operates with high torque and minimal noise - Non-contact switching of pumps in harsh environments (supports minimum ambient temperature of -40 degrees) - In fan drive applications, soft start reduces wear on V-belts - Easy installation even with high currents - Wiring errors are eliminated with SmartWire-DT connection Main features of S811+: - One of the world's smallest and most compact soft starters, featuring a cost-effective, compact, and space-saving design - Requires 58% less space compared to standard 30 kW star-phase starters. It also significantly saves space in control panels compared to competitors' products - Ensures safe continuous operation with comprehensive monitoring and protection functions - Overload protection - Equipped with Modbus RTU, allowing polling of data from all devices and monitors within the PLC. Network connectors for Ethernet/IP, Modbus TCP, Profibus, and DeviceNet (C441x) are also available as options.
