  • RTB Marine Rectifier and Battery Charger

RTB Marine

Raddrizzatore trifase 50-2000 A

Borri RTB range of Marine Thyristor Controlled 3-Phase Battery Chargers are designed and built for the harshest conditions and to provide high reliability power supply and battery charging capability. Using a powerful microprocessor to control all the functions provides reliable operations with ease of settings and communication.

Built with a rugged thyristor-controlled rectifier bridge suitable for charging nickel-cadmium or lead acid batteries while simultaneously supplying DC loads. It can also be used without batteries as a direct power supply.

  • Large LCD panel with mimic panel and history.
  • Wide selection of alarms, indications and measurements.
  • Electronic battery and charger output current limit.
  • Rugged thyristor bridge with isolation transformer.
  • Communication ports and potential free contacts.
  • 4 level battery charging including manual charge.
  • High MTBF and low MTTR.
  • 20 programable alarm and status LEDs.
  • Operates with Nickel-cadmium (vented/ gas recombination) and Lead acid batteries (vented/ gas recombination).
  • Advanced Battery Management.
  • Flexible in-built features.
  • Operation without battery (Rectifier).
  • Highly customizable.
  • Easy maintenance and serviceability.
  • Anti-vibration dampers (optional).
  • Internal rectifier input and output switches.
  • 6-pulse rectifier bridge with input isolation transformer.
