Electronic Load Controller.
This site has moved to www.hydroelectronics.net
Controllers are available for order on the new site.In order to make the power of your generator useable, you need to make sure the voltage (Volts) and the frequeny (Hz) stay stable. List of worldwide mains voltages and frequencies.
The AVR Automatic Voltage regulator takes care of the voltage.
The ELC takes care of the frequency.
Principle:
The higher the user load, the lower the frequency will get. So if you switch on the kettle, the frequency will drop. The ELC does nothing more than switching off an equal amount of power (wattage), so the frequency stays stable even after you've switched on the kettle.So in effect, the total amount of power consumed always stays the same.
To ensure this switching works as smooth as possible, the ELC uses a Proportional-Integral feedback loop, PI-Controller
