Scenario-Specific Adaptation:The SLNA Relay's core function is to control automotive preheating devices, precisely matching the short-term, high-load power demands of these devices. Its 15-minute rated operating time perfectly matches the automotive preheating process, allowing for direct integration with vehicle systems without additional adaptation.
1. Provides power-off protection during overload conditions.
2. Offers fault-induced power-off protection.
3. Helps the preheater function more effectively.
Automotive-Grade Performance Guarantee:The SLNA Relay can withstand extreme environments such as cold-weather starts and high-temperature engine compartment operation, preventing preheating failures caused by temperature fluctuations. An ultra-low voltage drop of ≤200mV reduces energy loss, and its 1×10⁵ electrical cycle and 1×10⁷ mechanical cycle lifespan meet the high-frequency preheating requirements of automobiles, ensuring stability and durability.
Easy Automotive Installation: The SLNA Relay uses QC quick-connect terminals, adapting to the efficient assembly processes of automotive production lines. Installation is secure and maintenance is convenient. The 12VDC/24VDC nominal voltage precisely matches mainstream automotive power systems. The simple A-type contact configuration adapts to the circuit control logic of the preheating device, and its lightweight 80g design does not add to the vehicle's load.
