Microprocessor Turntable PSU Set

[meldano]

Highlights:

- Sinus and Cosinus Output
- Output xx-22V (adjustable with pot) with standard transformer and high voltage (115/230) with step up transformer
- High Power Output with LM3886
- Adjustable phase shift between the two output phases
- Adjustable speed up ramp
- Adjustable frequence for two steps
- USB Configuration with PC Application (English or German)
- working hour timer
- easy assembly
- rock solid reliability and utter immunity to mains variation



One Set include a high quality black PCB, a programmed microcontroller and the data (bom, shematic, pc app...).
I ordered a batch of 10 Boards / Controllers to sell for a special price.

Price for the Set is 37€ + 10€ worldwide shipping by registered mail + paypal fee.

Would that board be suitable to use with stepper motors?

The PSU is designed for synchronous motor

Hi,

Is that version different than the once you had before? Meaning do I have to get that one as well? 🙂

Hi Nikola,

don't worry 😉
Only cosmetic (pad size, silkscreen...)

Would be interested in one as well. Would it be capable to drive a preamplifier as well?
and is the output separated from mains?

 

[meldano]

Hi,

the output stage is realised with two lm3886.
I think it is possible to drive a preamp or other small consumer.

What comes in the kit? Suitable to drive a Rega P3-24 turntable? Do the switches on the front allow adjusting to support 33rpm and 45rpm?

 

[meldano]

The Kit include a programmed microcontroller the PCB (unsoldered)snd all necessary data (part list, shenatic, pc app, infos).

It ist possible to set two different frequency values and chose them with the two pus buttons.

No problem to drive a rega sync. motor!

Hi Daniel,
would be interested in the Controller. Do you still have boards?
Best regards

[meldano]

Yes, see your PN 😉

This works really well with the Project 18v motor and it's even better with the Rega 24v. Rock solid speed stability with perfectly trimmed minimum motor vibration

For the Rega, did you retrofit an existing table? Did you bring out the third wire and bypass the internal phase adjustment and relay switching in the table?

Hello,
I'm interested to drive a 220v single phase Lenco motor. There is any schematic of the connection of the output transformer?
I wish you an Happy New Year

 

[meldano]

Use one 230/18V transformers 😉
Attached files show a dual phase motor with 115V.
