PCCU Combination Rectifier and Magnet Controller
The PCCU is a contactor based control system engineered for industrial lifting applications.
Product image not available.
OVERVIEW
The PCCU excels where instantaneous drop time is critical and environmental conditions would challenge solid‑state electronics. Ideal for scrap handling, high-throughput operations, and harsh industrial environments. Whether your application requires precision, speed, rugged durability, or multi magnet sequencing, Walker systems offer unmatched reliability. The rugged performance you'd expect in harsh environments! The PCCU integrates a transformer, AC‑to‑DC rectifier, and heavy‑duty lift/drop contactors in a single cabinet. This proven Walker design delivers the fastest load release available, making it ideal for scrap handling.
