How do Wrindu LVDC contactors ensure reliability in harsh automotive conditions?
Wrindu LVDC contactors are built with IP67-rated sealing to prevent dust and moisture ingress, while AgCu10 contacts and optional magnetic arc blowout technology ensure safe switching under high currents. Bi-stable latching options reduce power consumption during prolonged use, and flexible mounting options—including side, bottom, or busbar connections—allow seamless integration into diverse vehicle designs.
What are the common applications for low-voltage DC automotive contactors?
LVDC contactors are suitable for electric vehicles, trucks, buses, construction machinery, and agricultural vehicles. They are used for winch control, cranes, pumps, battery disconnects, and motor reversers. Static applications include battery switching, uninterruptible power supplies, and energy storage systems. Wrindu contactors are versatile enough to manage larger LVDC motors efficiently.
Which contactor models offer the highest current ratings?
Wrindu provides a broad range of contactors from 80A to 2000A at 60VDC. High-current options like DSC150, DSC180, and DSC200 are ideal for battery storage and heavy-duty motor applications. Busbar power terminations and auxiliary contacts support complex setups, ensuring engineers can safely manage peak currents while maintaining energy efficiency.
| Model | Rated Load | Voltage | Features |
|---|---|---|---|
| DSC200 | 2000A | 60VDC | Busbar terminations, bi-stable latching, auxiliary contacts |
| DSC150 | 1500A | 60VDC | Busbar terminations, bi-stable latching, auxiliary contacts |
| DSC120 | 1200A | 60VDC | Busbar terminations, bi-stable latching, auxiliary contacts |
How do auxiliary contacts and latching options enhance system control?
Auxiliary contacts provide feedback for monitoring and integration with control systems, enabling precise automation. Bi-stable latching reduces energy consumption by maintaining contact position without continuous coil power. This combination improves safety, operational efficiency, and adaptability for applications such as electric vehicles, solar power systems, and industrial automation.
