Whether you are repairing a vintage welder, building a 3kW solar charge controller, or maintaining a hospital-grade UPS, the RCT406 provides the electrical backbone necessary for stable, efficient DC power conversion.
Always discharge all capacitors in the circuit before testing. The RCT406 can hold a charge even when power is removed. rct406
Always consult the specific manufacturer’s datasheet for the RCT406 revision you possess, as parameters may vary by production lot. When in doubt, over-specify your heat sinking and under-specify your operating current (run at 30A continuous instead of 40A) to maximize the lifespan of this workhorse component.
