During initial startup, the power supplies operate in constant voltage mode, suitable for lights with internal drivers or in-seriesresistors(i.e. LED strip lights). Once the output current requirement exceeds rated current of the power supply and the voltage reaches the constant current region, t...

LED POWER SUPPLY Last update: 28 May, 2015 Page: 4 of 5 Electrical curves: .self-ecg note For constant current power supply,"LOAD" means the percentage of the maximum rated output voltage. For constant voltage power supply,"LOAD" means the percentage of the maximum rated output current. ...
What are the correct settings to force the power supply into CV, CC, CP mode? (CV = Constant Voltage, CC = Constant Current, CP = Constant Power) CV, Set current and power presets/limits to its maximum: CC, Set voltage and power presets/limits to its maximum:...
Switching Mode Power Supply Basics Why Use a Switching Mode Supply? A quick answer is high efficiency. In an SMPS, the transistors are operated in switching mode instead of linear mode. This means that when the transistor is on and conducting current, the voltage drop across its power path ...
