Features:
• Ultra-high voltage withstand performance: Withstands up to 5000 volts, providing excellent insulation performance, reducing the risk of circuit breakdown, and improving equipment operating safety.
• Flexible coil voltage: Supports a wide coil voltage range of 3VDC-48VDC, directly matching various control circuit voltage specifications without the need for additional voltage conversion components.
• Compact structural design: Small size, suitable for high-density PCB mounting scenarios, saving internal equipment space and improving circuit layout flexibility.
• High load switching capacity: Contact switching capacity up to 17 amps, with rated loads covering 10A 250VAC/28VDC and 16A 250VAC/28VDC, suitable for medium to high-power circuit switching needs.
• Dual authoritative certification: Certified by TUV and CQC, complying with international and domestic safety standards, meeting the needs of end-product applications in multiple markets.
• Convenient PCB assembly: Uses a 5-pin structure, facilitating easy soldering and fixing to printed circuit boards, resulting in high assembly efficiency and compatibility with automated production processes.
• Stable switching performance: Uses a single-pole single-throw (SPST) contact form, providing clear switching logic and stable contact resistance, ensuring the reliability of the circuit on/off switching.
Applicable Scenarios:
• Home appliances: Power on/off control for high-power small appliances (such as electric heaters, induction cookers), and automatic control of kitchen appliances.
• Industrial control: Signal switching and power control for industrial automation equipment, small PLC control modules, and motor control circuits. • Smart power equipment: Smart distribution boxes, power distribution modules, and charging pile auxiliary control circuits, adapted for high voltage and high load demand scenarios.
