LV Soft Starter

The LSD100-B series is a motor soft starter developed for overseas markets. The use of soft start has the effect of reducing motor starting shock, lowering starting current, and alleviating the burden on the power grid. The product is aimed at the global market and provides personalized customization. This series can customize the target country voltage, power frequency, and built-in multilingual menu through software adaptation upgrades and hardware adjustments. The product can be widely used in industries such as municipal HVAC, chemical metallurgy, solid waste sand and gravel, environmental pollution control, and agricultural and forestry irrigation. Can be applied to various motor equipment such as fans, water pumps, transmission machinery, compressors, hydraulic systems, etc

Key Features & Benefits

• High Machine Efficiency (99.9%): The HSD2000 series minimizes internal thermal and electrical losses during starting, reducing direct energy costs on large medium-voltage motor assets.
• Closed-Loop Voltage Ramp Starting: Solid-state SCR control ramps voltage smoothly from 0–100%, eliminating the heavy mechanical shock and voltage dips associated with direct-on-line (DOL) starting.
• Optical Fiber Control Communication: High-speed, noise-immune signal transmission between the control platform and power cells improves reliability in electrically noisy industrial environments.
• Intelligent Bypass Control: Automatically transfers the motor to bypass once full speed is reached, cutting heat generation and energy loss during continuous running.
• Complete Motor Protection Suite: Overcurrent, overload, short circuit, phase loss, three-phase unbalance, undervoltage and overvoltage protection are built into both the MV and LV series.
• Global Voltage & Frequency Customization: The LSD100-B low-voltage series adapts to target-country voltage, power frequency and language through software and hardware configuration.
• Flexible Control & Monitoring: Local control panel, external control, infrared remote and RS485 (Modbus RTU) options integrate with plant SCADA and DCS systems.
