multiple led controllers on one driver

[muh3]

Hello, as the topic already explains, is there a problem using 2 led controllers on one constant voltage driver?

Many thanks.

on one constant voltage driver?

on one constant voltage power supply.

There can be problems depending on how the "constant" voltage is produced. It may not be smooth DC, it may be a varying voltage that averages out at the stated voltage. This type of "DC" is OK when used to supply power to an incandescent lamp in which the thermal mass of the filament will smooth out the variation in the DC voltage. The power supply output should be labelled as V eff ( effective )

LED controllers .( properly refered to as variable current LED drivers ) may work on a V eff source but the variations in the voltage may result in the LED driver operating in an unstable mode.

Many power supplies labelled as electronic transformers are in reality switched mode power supplies (SMPS ) and these may produce 12 V eff by chopping a higher voltage on and off at several thousand cycles per second such that the average output is 12 volts.

Hello,

Thank you for your answer, the power supply I'm talking about is a MEAN WELL LPV-60-12, which I was planning to connect to 2 rgbw controller's/dimmer's which is controlling 2 led light strips in the kitchen.

Thank you.

The Mean Well device does appear to be a good quality device with a label that suggests the 12 V output is "smoothed" as it is not labelled as 12 V eff but as 12 V --- which implies it is smoothed DC

Does this mean I'm good to go?
