SQL50A 1200V Three-Phase Rectifier Bridge

This rectifier bridge is rated for three-phase operation at 50A and 1200V peak reverse voltage. It integrates a robust diode bridge group with an attached heat sink for thermal management. Designed for use with single-phase 35A brushless generators, it measures compactly to suit OEM replacement in confined equipment bays. Constructed from high-purity silicon diodes and aluminium alloy heat sink material, it delivers consistent forward conduction and reliable reverse blocking under sustained load. The unit supports stable DC output conversion in demanding applications such as automotive alternators and walk-behind or ride-on lawnmower charging systems. Its electrical performance remains steady across operating temperatures from -40°C to +125°C ambient, with resistance to vibration, dust ingress, and transient voltage spikes typical of engine-driven environments. Installation follows original equipment manufacturer (OEM) mounting patterns and terminal layouts—no modification or calibration required. Compatible with multiple common brushless generator models used in small engines and light-duty vehicles, it enables direct-fit replacement during routine maintenance or field repair.
