Fixture Driver

[Alwayslearningelec]

I pulled up spec sheet for fixture I'm estimating. Does below mean it's one or the other?(0-10v or 120/277v). Need to know if I need to bring dimming wires to it.

BTW the controls/switches are not specified so I can't even get clued in by that.

0-10 volts indicates the type of dimming. 120/277 volts is the input voltage to the driver.

0-10 volt dimming is 0-10 volt dimming.

This luminaire can operate at 120 or 277 supply volts, and likely anything in between?

The 1% is maybe minimum dimmed lighting output ability?

I agree that this is the most likely interpretation of the 1% spec. Some LED drivers will turn off the output when the 0-10V control is below some value, typically somewhere between 0.5 and 1.0VDC (aka "dim to off').

The driver, and probably the dimmer, receive unswitched power.

The 0-10v wire pair communicate between the two for dimming.

You don't have to use the dimming feature if you don't need it.

Or you can get dimming or non-dimming line-voltage drivers.
