Diversion Loads - Air Heating
for use with micro hydroelectric and wind generators
These diversion loads are used to dissipate extra electricity from wind and hydroelectric turbines to prevent overcharging batteries. Use the following formulas to compute and convert the electrical parameters.
To calculate current: amps = volts / ohms
To calculate power: watts = volts x volts /ohms
Do not exceed maximum allowable wattages.
Enclosed Versions - 900W/1200W max at 60V
These resistive loads enclosed in vented aluminum enclosures can be used in 12, 24 and 48 volt diversion regulation systems. The enclosure may get hot during operation and should be mounted at least 12" from any flammable material. Available in two versions: 4 ohm model which can be reconfigured to 1 or 0.25 ohms with a maximum dissipation of 900 watts or 3 ohm model which can be reconfigured to 0.75 ohms with a maximum dissipation of 1200 watts. Reconfiguration easily done at terminal block. Warranty 2 years.
Enclosure screws, jumpers and instructions shipped loose inside in plastic bag. Shipping can sometimes jar resistors loose from mounting clips and may need to be re-mounted at time of installation.
Finned Versions - 1900W max at 120V
This resistive load is finned and needs no enclosure. Resistance is fixed at approximately 7.58 Ohms and can be operated at up to 120V. Unit is 21" long x 2" wide x 1.37" high over the fins. Sheath temperature can reach 1200F when operated at 120V but will be significantly less at lower operating voltages. Includes high temperature porcelain terminal covers. Terminal studs are #10-32. See below for power dissipated at various voltages.
