Ratings follow the corresponding model columns in the linked ELG-100 specification. The electrical table separately lists 320VAC for 24 hours and 360VAC for one hour; neither is the continuous AC input range. Consult the static-characteristic and thermal curves before setting the load.
Choosing the output and control version
Match the LED load voltage to one of the three models, then check current and power at the intended AC input. The A version provides local adjustment. External 3-in-1 dimming and DALI belong to other suffix versions and should not be assumed for these A models.
Frequently asked questions
What output power is available at 115VAC?
For 100–180VAC input, the datasheet rates each of these ELG-100 models at 70W. The higher model-specific ratings apply at 200–305VAC.
What is the difference between ELG-100 A and AB?
A models provide built-in voltage and current adjustment. AB models add external 3-in-1 dimming. Both suffixes are listed as IP65 in the function table.
Can an ELG-100-24A replace a 36V or 48V version?
Only if the connected equipment is designed for its output. These are separate voltage models with different current and adjustment ranges; select the voltage required by the load.
Is 360VAC within the normal continuous input range?
No. The electrical specification lists 100–305VAC continuously, with 320VAC for 24 hours and 360VAC for one hour as separate limited-duration conditions.
