This device works quite well at lower currents (< 3A). MPPT via panel voltage tracking seems to work quite well. I have mine outputting an almost consistant 10 Watts(2.8A @ 3.6v) into a 1s20p Lithium battery(nom. 3.6v, 45Ah) from a 12.5 Watt panel (21Voc, 17Vmp), so approx. 80% efficiency, even in 42 degree celcius ambient heat with panel temperature above 60 deg C !! (Australian summer). In 'cooler' summer weather (mid 20's) I get maybe an extra Watt out at mid day (~11W -ish). Although this is advertised as working up to 5A, even after extensive testing I was not able to get much above 4A with a 25Watt(measured) panel and very good heatsinking: I only get 15 Watts out (4.2A@3.6v) so efficiency at higher currents suffers badly (25W in, 15W out = ~60% efficiency) This item, as shipped, will NOT work with 1S lithium because the regulation voltage can only be adjusted down to ~6.5v, however, it is relatively easy to modify it for 1S operation. To do this, simply replace the 22k resistor (R7, marked 223, 0603 size) with something around 75k to 100k. I used an 82k resistor which alows me to adjust regulation from ~3.0v to ~9v. Note that the supplied heatsink itself is okay, but it is useless as supplied because it is mounted with a thick dob of silicone adhesive. This is because A) the current sense shunt resistor is thru-hole and protrudes, and B) the PCB tracks under it have exposed solder pads. Poor design/lack of forethought by whoever did the PCB layout!. Therefore, mounting the heatsink directly to the PCB would cause a short circuit. I have modified mine with heatsinks on the top side packages(Mosfets and Diodes), and also a heatsink with a drilled hole (to clear the shunt solder pad) un the underside using double-sided tape as insulation to avoid shorts with the board tracks. Not exactly ideal, but much better than as-supplied.

Q: hi, is this A series or AN. I want to buy 30A versions

MrBungle Tracer A. It says so right there in the description.

MrBungle Arapaima666 is correct. The two centre terminals are connected together and are at GND potential.

MrBungle The Turnigy 9x IS a Flysky TH9X. Infact, the current version of the Turnigy 9X ships with the FS-RM003 module and an i8A receiver. So, yes this module will work with a 9x *BUT* if yours is an early version of the 9x, you will not have any telemetry unless you mod the 9x and also update the firmware to ER9X or OpenTX. The current 9x with RM003 module has a different mainboard and firmware to the earlier 9x versions.

MrBungle I realise this is old, but for anyone else wondering the same as brisi:The toolpost is not designed to take two holders at the same time.The 'side' dovetail is for normal turning/facing.The 'front' dovetail is for boring/facing.

Q: Will you be restocking the other colours?

zapytał MrBungle na 2018-05-17 06:44:02

Mobxweez Other colours can't be available, sold out.
