PRT™

PRT™, reliable and fail-safe thyristor rectifier for demanding industrial use

The PRT™ thyristor rectifier is a high-quality DC power supply developed and manufactured by ELLEGO™ in Finland since 1983. The device is specifically designed for demanding industrial electrolysis and plating processes that require reliability, precise control, and maintenance-free operation.

 

PRT™ is a cost-effective, stable, and customizable thyristor rectifier tailored to customer requirements.

Typical applications:

  • Electroplating (zinc, chrome, tin)
  • Anodizing and hard anodizing
  • Tinning
  • Gilding (gold plating)
  • Electrolysis in ore refining
  • Corrosion protection
  • Water purification

Key features:

  • Input voltage 230-690 Vac
  • Selectable output voltage range 0-750 Vdc
  • Selectable output current range 0-15 kA
  • 6- or 12-pulse rectification
  • 100 % duty cycle, 24/7 operation
  • Optional polarity reversal
  • Control modes: local control, remote control (via voltage or current signals), logic control (e.g. Profinet)
  • Ah-counter available for logic control

All electronics and control components of the PRT™ are housed in an IP44 enclosure. The combination of power transformer and rectification ensures efficient and stable DC output with minimal ripple, resulting in high-quality end products.

 

“We have used ELLEGO’s PRT rectifiers since 1995 and are extremely satisfied with their quality and reliability.” – Petteri Soraranta, Kova-Kromi Oy
