DC Resistor Air Elements

Weight: 2.0 kg

One of these air resistor elements can be used on 12 & 24V battery systems to divert surplus power up to 1kW to air heating. Two of these air resistor elements can be used together on 12,24 & 48V battery systems to divert surplus power (up to 1kW each) to air heating. Two resistors (0.8 and 1.0 Ohm) can be combined in many ways as per table below.

The power dissipated in a resistor is calculated as follows:

  • (fully charged battery voltage)^2 / resistance

Also check that the maximum current draw does not exceed 30 amps, this will depend on the size of SSR used (we have assumed a D1D40).

  • Current =  Power/fully charged battery voltage

Power in Watts (table below):

Please note: Must be mounted on a steel backing with suitable protection to eliminate any fire risk.
