Product Features:
• High Load Switching Capacity: Supports a maximum switching load of 30 amps (some specifications up to 40A), capable of handling the control needs of high-power equipment.
• Compact Design: Small size, suitable for high-density installation in space-constrained electrical boxes or control panels.
• Low Power Consumption: Coil power consumption as low as 0.9W, effectively reducing system energy consumption and heat generation.
• Multiple Terminal Options: Copper terminal products are available to ensure excellent conductivity and contact reliability when handling high currents.
• Wide Voltage Range: Coil voltage covers 3VDC to 48VDC, compatible with various control system voltage levels.
Typical Applications:
• Automotive Electronics: Used for high-power load control in automobiles, such as heaters, fan motors, and lighting systems.
• Heating and Ventilation Equipment: Suitable for industrial and household HVAC equipment, controlling heating elements or ventilation fans.
• Home Appliances: Used for power switch control in high-power home appliances such as electric ovens and microwave ovens.
• Industrial Control: Used as an actuator in automation equipment requiring high current switching.
