FAQs – Bridge Rectifier Modules

How do I choose the correct current rating?

Recommended selection:

  • Choose 3–5× the actual load current

  • For capacitive or inductive inputs → 4–5× recommended

When the current is above 10A, a heatsink is required.
For enclosed installations, adding a cooling fan is recommended for long-term reliability.


How do I choose the voltage rating?

Use at least 2× the AC input voltage to protect against voltage spikes.

Examples:

  • 220V AC → choose ≥ 600V rectifier

  • 380V AC → choose ≥ 1200V rectifier


What applications are your bridge rectifiers suitable for?
