Understanding Actuator VA

[FrancoisY]

Hello All,

I am outputting 108VAC, 120VAC, and 132VAC on the actuator, but the Voltage Amperage is staying consistent maybe +/-1.
What would be the root cause? other actuators I'm testing has an increase VA by voltage increase. Assuming there are so many possibilities, but maybe a few big item root cause?
I am unfamiliar with electrical.

Thank you,
FGY

Likely because there is an electronic drive circuit in your actuator.

as in the DC motor? if so, why aren't all the other actuators keeping the same consistent VA? nothing is different about these units

You are supplying AC to a DC motor?

Clearly. Out put usually means current leaving the device.

We don't know what actuator, what you're feeding it with, what you are actually measuring and how, what the control, system is, what the load is etc etc.

If the load is fixed and constant then the power will stay the same.

But give us more than 5% of the i formation and maybe we can work out what is going on.
