Hello,

I have a cc+CV HLG 320h 24b
I want to run strips soft, And would like to use 50% of the capacity right boa.

Im planning on a parralel strip build, Will this driver adjust
Itself?

So more strips parralel is lower current each strip?

The HLG-320H-24B (-B suffix) Driver will output 320 Watts but can be easily Dimmed down to ~ 32 Watts minimum with a 100K Ohm pot connected to the Dim wires (Purple and Grey) and adjusted down to 10K Ohm...

You can also use a 1/4 watt 1% Resistor with 50K ohm resistance for~ 50 % output, ~ 160 Watts. Connected Dim wire Resistance is Directly linear to Output, 10K - 100K Ohm is equivalent to 32 - 320 Watts output (10 - 100%).

The Driver will automatically adjust itself for the Voltage Range of ~ 12 - 24 Vdc and 320 Watt max output, to match the Vf (Forward Volts) of the LED Strips.

Yes, more Parallel connections results in less Watts per “Strip” , they will also operate cooler with higher efficiency, for example;
160 / 12 = 13.3 Watts
160 / 16 = 10.0 Watts

Thanks, but doesn't CV mean the voltage is fixed?
Don't know how cc and CV works together.

You’re welcome.

Yes, the Voltage is in the “Fixed“ Constant Current Range of ~ 12 - 24 Vdc.

The Driver’s internal circuits are configured to sense the “Range” or Vf (forward volts) of the LED Strips, Constant Voltage (CV) and also Control / Maintain maximum Current (Amp) output, Constant Current (CC) all while referencing the Dim setting.

Older technology LED drivers would vary the max Output Watts along with the varying Voltage to maintain a single fixed Amps (Watts = Volts x Amps). These newer MeanWell Drivers maintain their listed max output Watts at their CC range (Operating Voltage) , by varying the Current (Amps) ...
