B-Series Electronic Controllers

All-in-one controllers for high-efficiency professional refrigeration systems.

HIGH-EFFICIENCY CONTROLLERS FOR PROFESSIONAL REFRIGERATION

The B-Series covers compact all-in-one (BR5), DIN-rail (BR1-27) and split-mount power-unit (BD1-28, BR1-28) refrigeration controllers, with dedicated outputs for Variable Capacity Compressors (VCC) or EC variable-speed fans and enhanced ECO energy-saving management.

Key Features

  • Fully configurable relay outputs
  • Dedicated output for Variable Capacity Compressors (VCC), EC variable-speed fans or external relay (model dependent)
  • Enhanced ECO Energy Saving and defrost management
  • Real-Time Clock available (standard or optional, model dependent)
  • Wide choice of remote displays (split-mount versions)
  • Extended mains power supply
  • TTL or RS485 serial port with selectable ASCII/RTU protocol
  • Suitable for flammable refrigerants (A2L/A3) thanks to sealed relays (model depending)
