5V 12V 24V 50W 100W 150W 200W 350W Smps Power Supply For CCTV Camera And LED Light
So how do I know what type of LED driver I need?
The case for constant current drivers:
If you take a look at high powered LEDs, one unique characteristic is the exponential relationship between the applied forward voltage to the LED and the current flowing through it. You can see this clearly from the electrical characteristics of the Cree XP-G2 below in Figure 1. When the LED is turned on, even the smallest 5% change in voltage (2.74V to 2.87V) can create a 100% increase in current driven to the XP-G2 as you can see at the red marks current went from 350mA to 700mA.

| Remarks | ① Ripple and noise measurement method: use a 12 "twisted pair, and connect 0.1uF and 47uF capacitors in parallel at the terminal, |
| and measure at 20MHz bandwidth. ② The efficiency is tested at an input voltage of 230VAC, rated load, and an ambient temperature |
| of 25 ℃. Accuracy: including setting error, linear adjustment rate and load adjustment rate. Linear regulation test method: under |
| rated load from low voltage to high voltage test load regulation test method: from 0% - 100% rated load. The start-up time is |
| measured under the cold start state. The quick and frequent switch on and off may increase the start-up time. When the operating |
| altitude is higher than 2000m, the operating environment temperature needs to be reduced by 5 ℃ / 1000m |
