Would this item be an acceptable choice for testing my electrical system? Could it be used without any battery in the system? My avionics etc. are all Dynon.

Thanks,

Ken

Read the Amazon user reviews. There is a high percentage of dissatisfied customers.

Some builders just use an automotive battery along with a battery charger.

There is a used power supply on eBay, item number 360632236168 HP DL380 400W Power Supply HP.  But it requires soldering.  I am not necessarily recommending it, just saying that it is available.

I am already set up with an auto battery plus charger (I use it to power a small ATV winch in my shop for lifting things) so it would be simple for me to go that route. Wasn't sure if that was safe power for expensive airplane stuff.

What about a power supply from an old computer?

Thanks

A computer power supply could be used, but be careful with polarity.  A computer power supply has both positive and negative outputs.  The negative output has a much smaller output rating, so use the positive output.  A computer power supply voltage is only 12 volts, whereas an aircraft usually operates between 13 and 14 volts.  But that should not matter for most equipment.

I bought something like this.  I don't remember which vendor.

This one has adjustable voltage.  I bought one in this voltage range,  

so that I could have 14.2V after dropping through a protection diode.   

If the unit is not plugged in, but is "back fed" voltage from the  

airplane battery, it will be damaged, so put an eBus diode in series,  

then adjust the output voltage as desired.

http://tinyurl.com/lq7je4b

A computer power supply produces quite a lot of current at 5V, but not  

so much as 12V.  Some models require a load on the 5V output to  

regulate properly.

I just use a cheap 12v AGM battery for a UPS or alarm system. Works great, is safe, and I just charge it periodically. Dan
