Will this replace a v box ?

This is not service at all, it is just a try to assist to some crazy hobbyists. My pleasure.

The positioner was handed to be by a postman on a moped on saturday morning (through a kitchen window, but that's not relevant).
Even faster delivery than some well-known German sat pushers!
Thank you @RimaNTSS!

From the documentation, the device looks very much like a positioner for smaller sat-dishes.
It does not (readily) accept an external power supply, but relies on what's on the coax going in.
As far as I can tell from the somewhat sketchy (google translate from Russian?) documentation, it even has a 0.6A limiter built into the circuit, so an external power feed would make little difference.

Nevertheless, it is aimed at people with multiple LNBs on a motorised dish, e.g. with Ku-linear, Ku-circular, and C-band on the same dish.
Just not clear exactly what dish would yield good results on all three, and still be moved by a 0.4A current to the actuator? (Except from a limited arc-range dish, of course).
EXCEPT if you have a dish with an LNB changer, then you WOULD want to have a DiSEqC switch built into the positioner.
As I see it, this could be ideal for the LNB changer people using devices with linear actuators swtiching betweeb LNB 1,2,3 and 4...

I am no quit agree, I think that that power (current) used by actuator depends on relays used in the positioner (I think @a33 , meant this before ) . So, this positioner needs external 36V AS or DC power and can operate any actuator. Maybe I am wrong, but I do not think so.

Come on, I'm trying to use a language that the most esteemed and respected elders of this site will understand, and then I get nitty-grittied for my lack of keyboard-dexterity??

No, I think NWA has gone to your head and you cannot stop bopping ;)

Well, as far as I can tell (and I'm not an electronics expert), the circuitry passes on the voltage provided om the coax cable to the positioner +/voltages.
I also see no "external 36V power" input.
Of course the circuit could be "bent" to accept an external power input, but that's what I mean with "(readily)"...

Examinent mine , for shure there is a "external 36V power" input !
You may use a DC or AC adaptor , wire connection is "foolproof" by a little rectifier block .
The relais can switch 15 amps , but the restriction is the rectifier , only 1.5 amps .
By using a powerfull 36 V DC adapter and remove that rectifier and bridging the connections , give you useful "V-box" for reed sensored motors .
Cant see the limiter is built into the motor / relais line , I think only in the lnb F-conn. line to protect the receiver .
Have to look further , even a + 5 V connector could be possible .

Thanks @Trust1, I missed that bit. (But then, I am no electronics expert!)
It could be a very nice little device.
This makes it even more important to test the thing to see if it does what it says on the tin.
Does it work well with DiSEqC command chains, does it do it continously (no rebooting), and what's the signal pass-through like? What sort of degradation of the incoming signal?

Of course, We'll have to find a good source of 36V transfomers, but this is doable...

Just did some tests , without adapter , only relays just one click ( by the lack of pulses )
Switching ports and motor use in the same mode , possible .
With a actuator motor connected and shaft torturing till 3 amps (end of the amp meter of the 30 V power unit) still running .
Did not made a signal drop test .
My Jeager SMR1224 is running at a 30 V DC printer adapter , the elevation actuator at 19 V DC laptop adapter . Both with the use of a SG2100 circuitboard and separate relay interface .

Agree. I have piles of unused adapter (a good part even real metal transformer based) - these can be resued I am certain.
And in any case, the DARL actuators (notwithstanding the whole quality discussion elsewhere on the board) require not too much current, so the smaller dishes and accompanying actuators should work with this arrangement!
