Description
ELG-240 series is a 240W AC/DC LED driver featuring the dual mode constant voltage and constant current output. ELG-240 operates from 100~305VAC and offers models with different rated voltage ranging between 24V and 54 V. Thanks to the high efficiency up to 93%, with the fanless design, the entire series is able to operate for -40 °C ~ +90 °C case temperature under free air convection. The design of metal housing and IP67/1P65 ingress protection level allows this series to fit both indoor and outdoor applications. ELG-240 is equipped with various function options, such as dimming methodologies, so as to provide the optimal design flexibility for LED lighting system

DRIVING METHODS OF LED MODULE
This series is able to work in either Constant Current mode (a direct drive
way) or Constant Voltage mode (usually through additional DC/DC driver) to
drive the LEDs.
DIMMING OPERATION
3 in 1 dimming function (for B/AB-Type)
-
Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-: 0 – 10VDC, or 10V PWM signal or resistance.
Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers. -
Dimming source current from power supply: 100uA (typ.)
Note:
- Min. dimming level is about 8% and the output current is not defined when 0% < lout<8%.
- The output current could drop down to 0% when dimming input is about Ok or 0Vdc, or 10V PWM signal with 0% duty cycle.
DALI Interface (primary side; for DA-Type)
- Apply DALI signal between DA+ and DA-.
- DALI protocol comprises 16 groups and 64 addresses.
- First step is fixed at 8% of output.
Smart timer dimming function (for Dxx-Type by User definition)
MEAN WELL Smart timer dimming primarily provides the adaptive proportion
dimming profile for the output constant current level to perform up to 14
consecutive hours. 3 dimming profiles hereunder are defined accounting for the
most frequently seen applications. If other options may be needed, please
contact MEAN WELL for details.
Operating Time(HH:MM)
TIME matches Operating Time in the diagram whereas LEVEL matches Dimming
Level.
Example: If a street lighting application adopts D02-Type, when turning on the
power supply at 5:00pm, for instance:
- The power supply will switch to the constant current level at 50% starting from 5:00pm.
- The power supply will switch to the constant current level at 80% in turn, starting from 6:00pm, which is 01:00 after the power supply turns on.
- The power supply will switch to the constant current level at 100% in turn, starting from 8:00pm, which is 03:00 after the power supply turns on.
- The power supply will switch to the constant current level at 60% in turn, starting from 1:00am, which is 08:00 after the power supply turns on.
- The power supply will switch to the constant current level at 80% in turn, starting from 4:00am, which is 11:00 after the power supply turns on. The constant current level remains till 6:30am, which is 14:00 after the power supply turns on.
TIME matches Operating Time in the diagram whereas LEVEL matches Dimming
Level.
Example : If a tunnel lighting application adopts D03-Type, when turning
on the power supply at 4:30pm, for instance:
- The power supply will switch to the constant current level at 70% starting from 4:30pm.
- The power supply will switch to the constant current level at 100% in turn, starting from 6:00pm, which is 01:30 after the power supply turns on.
- The power supply will switch to the constant current level at 70% in turn, starting from 5:00am, which is 11:00 after the power supply turns on. The constant current level remains till 6:30am, which is 14:00 after the power supply turns on.
