HRDX Charge Controller Specification
HRDX Charge Controller – incorporates Pulse Width Modulation (PWM) technology to regulate battery voltage preventing overcharge in the same way as the HRS type regulators with additional features for battery management, monitoring and ease of installation. This generation of voltage regulation saw the end of the need for bulky heat sinks to dissipate excess energy generated by wind turbines and, more importantly for the lifetime of the windcharger, introduced speed limiting to the turbine when the battery is full.
For use with Rutland 503, 504, 913 & FM910-3 Furlmatic Windchargers.
Features
- The PWM electronic charge regulator tapers charge to the battery by gradually limiting windcharger current to avoid battery overcharge.
- When regulating the turbine speed is gradually reduced finally to an idle
- As fully charged batteries are more likely to occur in high winds this slow mode of operation is safer and reduces wear
- Built-in charge splitter enabling you to charge 2 separate sets of batteries, typically the services and engine batteries
- 5 Position switch for LCD allows you to see a display of: Windcharger current, Solar panel current, Net charge current to battery, Battery Voltage 1 & Battery Voltage 2.
- Charge source shutdown switch
- When switched this will stop the windcharger from running and the solar panel from generating power so the batteries are isolated from these charge sources
- Note that wherever possible this should be activated in low wind conditions or by slowing the turbine to an idle first.
- A solar panel with a maximum rating up to 100 Watts may be connected directly into the built in terminal. This connects the windcharger and solar panel in parallel
- A built in blocking diode prevents the wind & solar chargers from drawing current from each other
- Access panel to terminals for any one Rutland Windcharger 913, 910-3, 504 or 503 model, solar panel, battery bank 1 and battery bank 2.
- Built-in blocking diode protects the HRDX Controller from other charge sources to the same batteries, eg engine charging
- LED indicates battery full status.
- 12 Volt System regulating cut-in voltage 13.8 Volt, maximum charge voltage 14.4 Volt (+/- 2 %)
- 24 Volt System regulating cut-in voltage 27.6 Volt, maximum charge voltage 28.8 Volt (+/- 2 %)
- Product Dimensions: 160×137 x75mm Net Weight: 0.85 Kg
- Carton Dimensions: 215×170x105mm Packed Weight: 0.97 Kg

- Built in charge splitter for 2 isolated battery banks.
- 5 position switch for LCD digital display of:
- Windcharger current
- Solar current
- Net charge current
- Battery 1 voltage
- Battery 2 voltage
- Charge source shutdown switch.
- Wall mounted.
- Designed for use with Rutland 504, 503, 913 or FM910-3 plus up to 100w of solar panels.
