Rutland HRDi Charge Regulator

The latest wind & solar charge controller development from Marlec, the HRDi evolves from and improves on the successful HRDX controller.  The contemporary design meets the needs of ever increasing power demands and features a user selectable digital display.  The controller incorporates Pulse Width Modulation (PWM) technology to regulate battery voltage preventing overcharge. Charge control and split charging for use with Rutland 503, 504, 913 or FM910-3 Windchargers and up to 160W of solar panels.


Key Product Features

• Clear alpha-numeric digital LCD screen with user display options

• Connectable to two independent battery banks with voltages shown on display

• Push button activated and timer controlled back light

• Autoconfiguration to 12 or 24 V supply

• Latest technology micro controller based system shuts wind charger down when batteries are full

• Wall mounted modern moulded structure with easy access connection ports

• Manual shutdown switch

• Bulk and float phase charge control indicated on LCD

• Temperature compensation of charge voltage using internal sensor or external sensor also supplied

• Accepts up to 6 mm² cable (SWG 11 or AWG 9)

• The PWM electronic charge regulator tapers charge to the battery to limit current and avoid battery overcharge. When regulating the Windcharger speed is reduced.

• Standard regulator cut in level is 13.8 Volt and fully on at 14.4 Volt for 12 Volt systems   (24 Volt= 27.6 Volt – 28.8 Volt).

• Built in charge splitter for 2 isolated battery banks.

• LCD digital display of:
  • Windcharger current
  • Solar current
  • Net charge current
  • Battery 1 voltage
  • Battery 2 voltage

• Charge source shutdown switch

• Designed for use with Rutland 504, 503, 913 or FM910-3 plus up to 160w of solar panels.
