This review contains only the opinion thoughts of my own through my own investigative testing of the product. Static tests may not indicate real world performance of any equipment, but real world data will be provided as the testing proceeds.

The next set of tests that I have run are 10 minute tests of the regulator with the same loads and power source as the 3 minute tests. I had to switch to a lower-resolution data acquisition device(10-bits, about .2 volts) as the Fluke Scopemeter software would not allow me to change the 30sec/div display setting and the whole 10 minutes would not have fit onto the screen.

The new device is a DI-194 Data Acquisition board manufactured by Dataq Instruments, it was a freebie I recieved a long time ago when they were doing promotions, and although it's not greatest piece of data acquisition hardware around, their free software lets you change the display range.

Before I get to the data, I want to clarify that this is mostly the same setup as the 3 minute test, the only difference is that I powere a fan up on the bench to cool the regulator heatsink, as well as my load resistors.

As with the 3 minute tests, the regulator maintained the set voltage through the entire duration of the test and with airflow across the heatsink it barely got warm at all. It does not take very much airflow to keep the regulator cool, but just a little makes a big difference.


The first test was run at 5 Volts (+/- .2 volts), 2 Amps for 10 Minutes. The top graph is the regulator output and the bottom graph is the battery pack(2s2p home made Li-Ion pack)

The second test was run at 5.5 Volts (+/- .2 volts), 2.2 Amps for 10 Minutes. The top graph is the regulator output and the bottom graph is the battery pack(2s2p home made Li-Ion pack)

The third test was run at 5.5 Volts (+/- .2 volts), 2.2 Amps for 10 Minutes. The top graph is the regulator output and the bottom graph is the battery pack(2s2p home made Li-Ion pack)

The regulator is performing well throughout these tests, you may be wondering why I haven't tested the gyro regulation with the primary regulator, that will come in due time. So far I am pleased with the test results.

Please keep watching for Page 3 (Primary + Gyro Reg Tests) Page 4 (Real World Testing 1) and Page 5(Real World Testing 2) of this article....
