How to use 0-3.3 volt analog output to control 0-10 Volt VFD ?

[RadiantHeat]

I don't know what circuit or device to use to interface the Pokeys analog output to a 'standard' VFD. The VFD requires 0-10 Volts to go from stopped to full speed.

Thanks in advance !

CNC4PC has a model C14 0-5 volt converter which can deliver a output of 0-10 volts  , (For only $12.28) , but my pokeys unit only goes to 3.3 volts ?

Hi!

Ask Arturo from CNC4PC what should be changed for 0-3.3V input.

if you VFD (check you programming manual), it may have an Analog Offset that you can scale to the 3.3

Just a small-signal PNP transistor with a 10-12 volt external power source should do the trick. NTE 59 or equiv. should do it.

Transistor is not linear at it ewill not do the work correctly.
