6 KW Heater Controller
With optimal power point tracking for Scirocco wind turbine
Description :
Our 6kW Heater Controller provides a simple and economic way to realize direct heating
applications with our 6kW Scirocco wind turbine.
It is intended to directly works with standard 230Vac heater resistors, and thus can easily adapt to
existing installation.
Features :
•6000W rated output with 5kW to 7.5kW (@ 230Vac) rated resistors.
•Possibility to connect 2kW to 9kW rated resistors (with derating).
•All working parameters and settings are displayed on a unique and large LCD display with keypad,
and there is no need for any additional metering or display device.
•Total produced energy is internally recorded and can be displayed.
•Programmable maximum voltage-current-power allows to perfectly tune the installation in case of
re-employ of existing heaters.
•Digital input for remote control ( output ramp up/ ramp down).
•Internally self powered by the wind turbine generator. No need for any other power source.
•Noise free DC output (PWM converter, 20khz IGBT switch) doesn’t generate any mechanical noise
in the heater resistor.
•Specifically designed to work with Scirocco Wind Turbine, variable speed management and our
unique DSP controlled Maximum Power Point Tracking system ensures maximized wind power
extraction, even in low wind conditions, and low noise.
Eoltec’s power electronics are manufactured and developed in exclusive cooperation with leading innovative
inverter manufacturer, MLT Drives CC (South Africa – www.mltdrives.com - [e-mail] )

Cautions and Warnings
WARNING
THE HC- 6K HEATER CONTROLER GENERATES
HIGH VOLTAGES AND CURRENTS.
INCORRECT USE MAY CAUSE ELECTRICAL SHOCK AND DEATH.
•This manual is only for use with the HC- 6K Heater controller.
•The HC- 6K Heater controller contains sophisticated electronic equipment and must be installed by a qualified
electrical technician. Any queries must be referred to the appropriate service provider.
•Any work performed on the HC- 6K Heater controller and the installation of the HC- 6K Heater controller must comply
with local and national electrical regulations.
•All precautions relating to the installation and operation of mains voltage equipment must be observed when installing
the HC- 6K Heater controller. This includes considerations to insulation of cabling, access to bare conductors,
grounding, protection from moisture etc.
•Do not operate the HC- 6K Heater controller with any panels or covers removed. Do not operate the HC- 6K Heater
controller if it is not properly installed.
•After being disconnected, the HC- 6K Heater controller may still contain high voltages in the capacitors. Ensure that
these have been fully discharged before working on the HC- 6K Heater controller.
•Do not use the HC- 6K Heater controller outside the permissible ambient conditions.
•Do not short the inputs or outputs of the HC- 6K Heater controller while the HC- 6K Heater controller is running, as
this can cause damage to the HC- 6K Heater controller.
Warranty
•Warranty is for two years from date of purchase.
•No liability is accepted for any damages occurring through use, manipulation, working situations and handling which
are not explicitly mentioned in these operating instructions.
•The following cases are not covered by the warranty:
oReverse polarity on Battery connections (+/- reversed)
