Coleman Air


25 Amp, 1500 Watt, 48 Volt Diversion Load Center

Designed for use with Diversion Controllers

Now with custom made Kanthal-A1 wire wound, high heat elements.


This Diversion Center Can be mounted on to a wall to provide heating as well as serve as a diversion (dummy) load.

These resistors have been custom made (here in Coleman Texas) specifically to perform as diversion (dummy) loads in solar/wind/hydro alternate energy systems. Unlike water heating elements, this unit does not need to be submerged in water or oil. It will operate in free air.

Each of the resistors we sell has been selected (or custom made) based on it's ability to dissipate a very specific amount of power (watts) with a very specific resistance value (ohms), at a very specific voltage. When used as recommended, they will not burn out, even under continuous use.

Please note. These resistors will become hot during normal use, please mount them away from heat sensitive objects and out of the reach of children.

The diversion load center consists of six resistors mounted directly onto two sheets of CNC cut, .063 aluminum (A left and right sheet). These two sheets form the electrical connection for the six resistors. Both sheets are mounted to a solid piece of ceramic board. Two terminals with aluminum nuts are provided for a solid connection to your wiring. The entire unit is enclosed in a Hoffman 12 x 16 x 4 enclosure with a vented cover



Load specs per resistor.

Ohms Volts Amps Watts

Area in green is where most diversion controllers would be set to divert.
This Diversion Center consists of six - 15 ohm resistors. Each 15 ohm resistor will dissipate 3.8 amps at 58 volts. This is 224 watts/resistor. 6 resistors in parallel will dissipate 1343 watts at 58 volts (23.16 Amps), or 1440 watts at 60 volts.


This Diversion Load center is a perfect companion to a 1500 watt 48 volt wind generator and our C440-HVM controller. Please see our other listings for 12 and 24 volt diversion centers.


Please contact us if you have wiring questions.



More to come:
Put us on your watch list, we are currently working on a series of new products specifically for the solar/wind market.

Big things are happening from a lot of little companies, and if you notice the truly innovate products are being released from the new kids on the block.


Due to major delays in customs, we no longer ship to Italy.
