RTB Compact

Raddrizzatore trifase industriale 50-200 A

The RTB Compact is designed to cover the lower range of industrial chargers but still offering all the functions and controls with Borri microprocessor controller providing 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.

  • Proven microprocessor control.
  • 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 optional manual charge.
  • High MTBF and low MTTR.
  • Operates with Nickel-cadmium (vented/ gas recombination) and Lead acid batteries (vented/ gas recombination).
  • 10 programable alarm and status LEDs.
  • Advanced Battery Management.
  • Flexible in-built features.
  • Operation without battery (rectifier).
  • Easy maintenance and serviceability.
  • Internal rectifier input circuit breaker and output switch.
  • 6-pulse rectifier bridge with input isolation transformer.
  • Output LC ripple filter.
  • Rectifier protection fuse.
  • Advanced Multi-functional LCD panel with active mimic diagram.
  • Audible alarm.
