Binary Load Controller
230Vac single phase output
10A 2000VA max
This is the "brains" for our NPAT series micro hydroelectric systems. It regulates the output voltage of an induction generator. If you want to assemble a micro hydroelectric system using your own turbine, induction generator, diversion load resistors and excitation capacitors you can purchase this controller board and user interface.
NoOutage.com is introducing this new product to fill the need for simpler micro-hydro electric power. The design is based on research by Arthur Williams and Dr. Nigel Smith in the UK. They have installed these type systems at many sites in third world countries. Approximately 100 units have been operating successfully for years providing electricity to villages where grid power is either unavailable or unaffordable.
The turbine drives an induction generator producing ac power without the need for an expensive DC-AC inverter or battery bank. And since the generator output is at 230Vac the electricity can be transmitted many hundreds of feet without using oversized conductors commonly required with low voltage DC systems. If the distance is longer, such as over 1000 feet, a step-up transformer can be used operate your transmission line at 460V or 600V.
Many Unique Features
The controller, LCD display, user interface pushbuttons and
interconnecting ribbon cable are included. You provide the turbine,
induction generator, capacitors,
diversion load resistors, breaker
protection and enclosures to complete the system.
Load Controller:
* Voltage is regulated using a binary diversion load
controller.
* Since this type of controller does not chop the ac wave it
can provide clean power quality with virtually no
harmonic distortion.
Other cheaper SCR controllers chop the ac wave causing very bad distortion and
RFI noise.
* 32 load steps for accurate voltage control and regulation.
* Response time typically 1 cycle (17 milliseconds for 60 Hz system).
* Microprocessor-based with many settings
adjustable in the field by user.
* Complete control via three push buttons with LCD display.
* Settings are automatically stored in EEPROM memory and are not lost when
system is turned off.
* Designed so that no batteries are required for control power.
Self-powered from generator.
* Displays diversion load watts, output load watts, volts, frequency, and more.
* Will automatically disconnect output load when abnormally low voltage is
sensed. Prevents loss of
generator magnetism that would cause problems upon restarting
system.
* Microprocessor installed in Ziff socket for easy change out (in case of
future software upgrades).
* maximum output 10 amps at 240Vac (fan cooling required for max rating)
This controller can be used with our NPAT-DLOAD Diversion Load.
