Power
Combiner
The Ideal Diode Power Combiner takes two power sources and combines them into one, creating redundancy without sacrificing efficiency.
A power diode may drop a volt or more when carrying 80 Amps. This may not sound like a lot, but at 80 Amps this equates to 80W which is a lot of power to get rid of as heat. The Ideal Diode Power Combiner typically drops less than 100mV at the same current, equat-ing to less than 8W.
Features
- 65 VDC, 80 Amps (5000W max.)
- Inputs reverse polarity protected and tolerant of transients up to +100V.
- Robust mechanical enclosure
- Potted PCB for Ingress Protection
- Weight: est. 290g
- Dimensions: 92.5 x 86 x 22
Operation
The Ideal Diode Power Combiner works just like a pair of diodes with their cathodes connected together: power enters at the anodes and exits at the cathode. There is, however, a key difference to be aware of.
Unlike diodes – which do not need a ground connection to work correctly – the Ideal Diode Power Combiner must have a ground connection because it contains active devices. A ground terminal is provided for both of the input terminals and also for the output terminal. These are all connected together internally. At least one ground terminal must be connected.

High power rating
Safety for your UxV
Redundant output
Use with ESCs
One possible application for this device is to power an ESC (Electronic Speed Controller) from a pair of batteries. Be aware that regenerative braking only works if there is a path for regenerated current to make its way back into the batteries, and any sort of diode – real or ideal – in the way will prevent this. Regenerative braking must be turned off in this situation or damage will occur.
