Specialized Switching for Photovoltaic and Storage Systems
Our DC Load Switch is designed for the unique needs of DC power systems. This product covers DC1000V and DC1500V voltage levels. These are the standard DC platforms for solar arrays and battery systems. The switch is used in photovoltaic combiner boxes and DC distribution cabinets. It is also used in battery storage enclosures for routine switching. The switch closes and opens DC circuits under load. This is more difficult than AC switching due to the arc problem. DC current has no zero-crossing point. The arc created during opening is harder to extinguish. We solved this challenge with specialized magnetic blow-out structures. The product uses a permanent magnet arc blow-out design. This system forces the arc into the arc chute quickly. The arc splits into multiple short arcs and extinguishes rapidly. The contacts are made from silver-tungsten alloy. This material resists arc erosion better than standard materials. It maintains good contact condition even after many switching operations.
Reliable DC Operation with Magnetic Arc Extinction
This DC Load Switch handles high DC currents safely. The arc chamber uses strong magnetic fields to control the arc. The field moves the arc into arc-splitting plates rapidly. The arc is divided into many small arcs and extinguishes quickly. This design minimizes contact damage during switching. Even large DC currents are interrupted within a very short time. The switch is ideal for PV array combiner and grid connection control. It also works for battery cluster switching in energy storage systems. The product includes auxiliary contacts as standard. These contacts send open and closed status to the monitoring system. This provides remote visibility of switch position. The DC LBS series is our dedicated DC load switch product. It supports the growing renewable energy and storage market.
Professional Support for DC Projects
Our DC Load Switch comes with 12-month warranty coverage. We provide complete technical documentation with each shipment. Our team helps you select the right switch for your DC application. We understand the specific challenges of DC system design. The product's magnetic arc blow-out ensures reliable DC interruption. This technology has been proven in many renewable energy projects.
