Overview

Rectifiers convert alternating current (AC) to direct current (DC) using diodes, SCRs or bridge assemblies. They come as discrete modules, rack-mounted units, or integrated power supplies for industrial applications. Rectifiers are used in welding, electroplating, battery charging, and DC motors, and vary by voltage, current rating, cooling method, and control features. Buyers check specifications, cooling, and protection features to match load and environment.

FAQ

What should I consider when buying a rectifier?

Verify output voltage and current ratings, duty cycle, form factor, cooling method, control features and protection (overvoltage/overcurrent). Ask for test reports, maintenance history and spare parts availability.

How do I ensure safe shipping of a rectifier?

Secure and palletize the unit, protect terminals and cooling openings, use vibration and moisture protection, label heavy loads and choose a carrier experienced with electrical equipment and local regulations.

What regular maintenance does a rectifier need?

Keep cooling paths clean, inspect and service fans/heatsinks, check connections and fuses, measure output voltage/ripple periodically, and replace worn diodes/SCRs or aging capacitors as needed.
