Frequently Asked Questions
Can I adjust the output current of the ELG-100-C500A to fine-tune LED brightness without a dimmer?
Yes. The A suffix indicates this driver includes an output current adjustment potentiometer, allowing the output current to be trimmed from the rated 500mA level. This lets installers optimize LED brightness or match specific LED current requirements without relying on an external dimmer.
Is the ELG-100-C500A appropriate for driving LED modules in an indoor commercial luminaire?
Yes. The driver delivers a constant 500mA across a CC voltage range of 100–200V and accepts 100–305VAC input, covering all common commercial mains voltages. Its IP65 water-resistant rating is appropriate for indoor recessed or surface-mount luminaire applications.
What is the IP65 rating of the ELG-100-C500A and does it affect outdoor use?
IP65 provides complete protection against dust and protection against water jets from any direction. This makes the ELG-100-C500A suitable for outdoor installations that are sheltered from direct rain exposure, such as under-canopy or covered walkway lighting, but it is not rated for immersion or heavy water exposure — the IP67 variant (ELG-100-C500B) would be required for those conditions.
How do I determine if the ELG-100-C500A can drive my LED strip or module string?
The driver supports a CC voltage range of 100–200V. Add up the forward voltages of all LEDs in your series string and confirm the total falls within that range. The driver will maintain a constant 500mA through the string, so individual LED forward voltage — not a fixed LED count — determines compatibility.
Does the ELG-100-C500A support dimming in addition to current adjustment?
No. The A suffix indicates output current adjustment via potentiometer only — it does not add external dimming signal support. If dimming control via 1–10V, PWM, or resistance is needed, the ELG-100-C500AB (which adds both adjustment and dimming) or ELG-100-C500B (dimming only) would be the appropriate alternatives.
