Product Description and Operating Instructions
You have purchased a system that harnesses a readily available source of renewable energy – Human
Power. It is user friendly, portable, and available whenever you have the need for it. The power
output is directly proportional to the effort put into it. The Human Power Generator can be a
valuable tool in teaching an appreciation of the power we often take for granted.
Applications
•
Emergency power generation and 12V
battery charging.
•
Exercise systems that do useful work
generating power while exercising.
•
Remote or off-grid power for 12-volt water
pumps and small appliances.
•
Independent radio or radiotelephone
systems; emergency communications.
•
Classroom projects and educational
exhibits to demonstrate the physical effort
required to generate electrical power.
The Human Power Generator is a DC power source primarily designed to charge a 12V battery. It will
charge at a rate of between 3-5 amperes. It will provide a maximum of 75 watts. Sustainable power
output over a period of time is usually around 50 watts. It is ideal for low power appliances like
laptops, radios and lighting. AC appliances can be powered by the Human Power Generator when a
DC/AC inverter, connected to the battery (often in the form of a portable power pack), is used.
Please note
: It is possible to directly power certain DC appliances without using a storage battery. It
is important to observe maximum voltage ratings. An appliance rated for 12V DC will be damaged if
too much voltage is delivered. For example, a 12V lightbulb may be able to absorb 13V momentarily
but any more voltage would cause the bulb to burn out and fail. We recommend that DC Direct
applications be voltage regulated or closely monitored with a dc voltmeter or multimeter to
accurately measure output. The HPG can produce up to about 16V when connected to the load in
short bursts if the pedals or hand cranks are given a very quick turn.
Note
: Windstream’s 12V
Educational Light Box is voltage regulated.
