Opinion on the production of high voltage function generator shield

Other Hardware General Electronics

hello. Forum Families.

I am trying to make a function generator shield that supports 0~200V.

Approximate specifications

Driver Output wave : Sinusoidal, Square, DC
Driver Output Range: 0 ~ 180[Vpp_sinusoidal] (In this case, it has a range from 0 to Vpp.), 0 ~ 200[Vpp_square, Vpp_DC]
Driver available frequency : 10 ~ 10,000[Hz]
Laser Control Output Range: 0 ~ 40 steps

Currently, we are using MEMS resonant drives or PZT motors.

I'm thinking about the price of around $400-$500.

  1. Are there any additional features you need to see?

  2. Do you think the price is right?

  3. If so, is there anyone willing to buy?

Any comments would be appreciated.

thank you. I hope you have a nice day. :slight_smile:

I think the price is high for a shield. I use an amplifier with a standard function generator. You neglected to show in your specifications the output impedance you are delivering the 200 volts into. Assuming the standard 50 Ohm load you need 4 amps or at 100% on or about 800 watts of power.

Personally I would never have a high voltage close to any low voltage (cpu, frequency synthesiser etc) when using Arduinos and shields; I would put the actual power part (5V / 12V to 200V) on a separate PCB. But that might be me being paranoid.

For your shield, it would advise to add mounting holes so a (e.g. transparent) cover can be placed over the high voltage part using standoffs; less risk that people electrocute themselves.
