Product Introduction
The TL913-200 Series magnetic DC latching relay is a high-performance power relay designed by Mingni Tech for demanding applications requiring exceptional current handling capabilities. With a rated current of 200A and maximum switching voltage of 2770V AC, this high current relay delivers reliable performance in critical power management systems.
This bistable relay features low power consumption with pulse-driven operation, requiring only a brief 50ms pulse to switch states. The innovative magnetic latching mechanism maintains contact position without continuous power, significantly reducing energy consumption. With 4kV isolation between contacts and coil, the TL913-200 ensures operational safety in high-voltage environments.
Engineered for durability, this power latching relay offers a mechanical life of 100,000 operations and electrical life of 6,000 operations at 150A/250V AC. The robust silver alloy contacts provide minimal contact resistance (1mΩ max) while the compact design (47.2×34.6×22.1mm) enables space-efficient integration in power distribution systems.
As a specialized DC latching relay, the TL913-200 is particularly suitable for electric vehicle charging infrastructure where high-power switching and energy efficiency are critical requirements. This charging relay is also ideal for smart grid applications, remote power control systems, and industrial automation where reliable high-current switching is essential.
