Product Advantages:
Ultra-High Voltage Isolation: Withstand voltage between contacts up to 6000V, providing excellent high-voltage isolation capabilities for PCB-level relays, effectively blocking high-voltage interference.
High-Voltage Low-Current Switching: Optimized for switching weak currents under high voltage (e.g., 10mA @ 1500VDC) or conventional currents under low voltage (e.g., 1A @ 30VDC), with a clearly defined application range.
Sealed Long-Life Structure: The reed switch is sealed in an inert gas, with no moving wear parts, resulting in an extremely long mechanical life and immunity to environmental dust and humidity.
Key Features:
Multi-Level Load Specifications: Supports various load conditions: 10mA/1500VDC, 15mA/1000VDC, 1A/30VDC, accommodating both high-voltage microcurrent and low-voltage conventional current scenarios.
High-Sensitivity Coil: Low coil driving power consumption, compatible with 3-24VDC low-voltage control signals, easily driven directly by integrated circuits.
Compact PCB Mounting: Miniature package design, directly soldered to the PCB, saving space and suitable for high-density instrument internal layouts.
Fast Response: Rapid reed switch action and short switching time meet the timing requirements for signal sampling in instrumentation.
Main Applications:
Safety Monitoring Equipment: Used in high-voltage signal sampling or test circuit switching in insulation monitors, withstand voltage testers, and fault arc detectors.
Precision Instruments: Integrated into high-precision power supplies, meters, and medical imaging equipment (such as X-ray high-voltage generator control) to provide high-voltage isolation and signal switching.
Communication and Industrial Control: Used as a reliable isolation and switching component in communication interfaces and PLC high-voltage input modules requiring high potential isolation.
New Energy Systems: Applied in voltage sampling isolation circuits of photovoltaic inverters and battery management systems (BMS).
