Features:
1. Magnetic Latching Function: Uses pulse excitation; the coil consumes power only during the switching moment, and the contact state is self-locked after power off, significantly reducing system energy consumption.
2. High Load Switching: Contacts support 8A current switching, meeting the high-power control needs of household appliances such as air conditioners and microwave ovens.
3. High Withstand Voltage Isolation: The withstand voltage between the coil and contacts reaches 5000V, providing excellent electrical isolation performance and ensuring the safety of the control circuit.
4. Compact Design: Small size and compact structure, ideal for high-density mounting on PCB boards.
5. Wide Voltage Coil Range: Offers various coil specifications from 3VDC to 48VDC, adapting to different control voltages.
6. Safety Certification: TUV and CQC certified, complying with international safety standards.
Typical Applications:
1. Communication Equipment: Used in communication base stations and switching equipment for low-power circuit switching and signal routing.
2. Household Appliances: Suitable for air conditioners, microwave ovens, and other equipment as an energy-saving power control switch.
3. Security Equipment: Used in security alarm systems and access control to ensure that the original locking or alarm state is maintained even in the event of a power outage.
4. Office Equipment: Applied in office automation equipment, such as copiers and printers, to reduce standby power consumption.
