DC Power Supply

[SignTorch]

The recommended gecko drives can take 20 amps and 18 to 80 volts, so a 60 volt 20 amp unregulated toroidal transformer will be ideal.

Don't use over 60 volts, to leave headroom for voltage spikes.

We usually also will need one or two 5 volt regulated DC power supplies to power the breakout board, components, and signals.

I used Unregulated Linear 1200W/60VDC/20A Toroidal PSU (KL-6020) | Automation Technology Inc for $189.00

It comes with one regulated 5 volt output.



You can use less volts and amps and or switching power supplies.

Higher voltage means higher top speed. More amps means more acceleration.

Do you no the volts the z-motor runs on ???

not specifically - I'm using 60 V - the stepper driver limits current in which case higher voltages can be used without overheating the motor - mine doesn't even get warm - I'm not sure how low the voltage could be - 12 or 24 V might work but lower voltage means less torque which means less power, less speed, less velocity, and less acceleration, so higher is better.
