รีเลย์ตรวจสอบแรงดันไฟฟ้า VM110

Littelfuse VM110 Voltage Monitoring Relays are designed for electrical systems to ensure reliable and safe operation. These relays monitor the sequence of phase voltages, preventing incorrect rotation of three-phase motors, detecting undervoltage conditions, and identifying overvoltage situations. By monitoring these conditions, the VM110 relays from Littelfuse protect equipment from potential costly or critical damage, malfunction, or operational failure. Additional features include adjustable setpoints for undervoltage and overvoltage thresholds and phase sequence detection, providing a voltage protection solution in industrial applications.
