DSX12V Puts out 15 amps PEAK!!!!
Engine Crank Pictures:
Rather than speculating on what the DSX12V will deliver and if it will survive crank, I decided to apply the good old scientific method.
I used 12 gauge wire for this experiment. I ran about 9 feet from the positive terminal of the battery to VIN of the DSX12V. This simulates the unit in the trunk or something. I ran 5 feet from the Negative Terminal of the battery to the GND of the DSX12V. I used less here because the Chassis is a much better conductor anyway and most people will use about 2-3 feet from the chassis to the negative terminal of their power supply anyway.
I connected a Resistor Load Board to the Output of the DSX12V. I could measure current and voltage on both the VIN and the VOUT terminals.
I hooked up an oscilloscope to voltage AT THE BATTERY and the voltage at the output of the DSX12V.
CH1: Voltage at the Battery
CH2: Voltage on output of DSX12V
I was able to set the output load on the DSX12V from 0 to 16 amps. I started the Car with the load set to 7,12,13,15,16 amps.
The scope plotted the results.
One thing is for sure; the supply can deliver a constant 12 amps no problem and 15 amps peak. (Iím still going to de-rate it to 10 amps with 13 amps peak. (120-watt supply))
Iíve developed a power supply capable of 144-watts with 180 watts peak. Wow, I canít wait to get it to market!
Those of you who have contacted me Iíll be getting back to you shortly.
Does anyone want to pre-order one so I can get rolling on this?
