Works well for my solar generator application
Review for MGGi DC Converter 8V-40V to 12V 6A 72W. I'm using this device to provide regulated 12 VDC power from a DIY solar generator to a few electronic devices including an internet modem, a router, a 12 VDC to 19 VDC laptop power adapter, and a couple of small battery chargers that require 12 VDC. The battery voltage on the solar generator can range from 11.0 volts to about 14.7 volts. I didn't want to send this range of voltages directly to these electronic devices, hence the use of this converter.The converter seems to be well made and looks to be of good quality. Note that the two negative (black) leads, one for input and one for output, are tied together inside the unit as shown by an ohm meter reading of 0.0 ohms between these two leads. Therefore, the input circuit and the output circuit are not isolated from each other, and I was able to tie the two negative leads together when wiring this device. I have operated this converter for 7 days 24 hours per day with a load of 1 to 3 amps on it, with input voltages ranging from 14.5 volts to 11.4 volts. During this time, the converter output voltage always read 12.1 or 12.2 volts, regardless of the input voltage applied. Note that the meter that I was reading this voltage from only displays one decimal place, so the output voltage may have only been varying by a few hundredths of a volt.Under a load of 1 to 3 Amps, the unit was just slightly warm to the touch, certainly not hot. I expect that the unit might get quite hot if it were operated at its full 6 amp rating. I mounted this converter on a thin piece of aluminum to act as additional heat sink surface area, but that was probably overkill for my application.I am using this device in the same room as a ham radio. So far I have not noticed it causing any RF interference on the ham radio, although I am not using the output of the converter to power the ham radio since the maximum allowable input voltage of the radio is higher than the unregulated voltages that the solar generator will ever put out.Based on my experience with this unit so far, I am very pleased with it and would certainly buy another one for other projects.
