NOTE
1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25
℃
of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel
capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.

DRIVING METHODS OF LED MODULE
There are two major kinds of LED drive method, "direct drive" and "with LED driver".
A typical LED power supply may either work in "constant voltage mode (CV)" or "constant current mode (CC)" to drive the LEDs.
Mean Well's LED power supply with CV+ CC characteristic can be operated at both CV mode (with LED driver, at area (A) and CC mode (direct drive, at area (B).

(A) Constant
Voltage area
(B)
Constant
Current area
In the constant current region, the highest voltage at the output of the driver
depends on the configuration of the end systems.
Should there be any compatibility issues, please contact MEAN WELL.
