Frequently Asked Questions

Can the ELG-100-42A power an adjustable LED lighting system where I need to fine-tune brightness?

Yes. The ‘A’ suffix means the ELG-100-42A includes an output-adjustment potentiometer that lets you trim the output voltage within the 21–42V CC range. This is useful when a fixture requires a slightly lower drive voltage to reach a specific lumen level without adding an external controller.

Is the ELG-100-42A suitable for outdoor LED strip runs in covered but exposed areas?

Yes. The ELG-100-42A is rated IP65, meaning it is fully dust-tight and protected against low-pressure water jets from any direction. It is appropriate for covered outdoor areas such as canopies, soffits, and car parks where direct rain splash is possible but water immersion is not expected.

How many meters of 42V LED strip can the ELG-100-42A support?

The driver delivers a maximum of 95.76W at 42V. For a 42V strip rated at 10W per meter, that allows approximately 9.5 meters at full load. Check your strip’s rated power per meter before finalising the run, and include a 20% derating margin for long-term reliability.

Can I use the ELG-100-42A with a 42V architectural LED cove or linear fixture?

Yes. The driver’s 95.76W / 42V / 2.28A output suits medium-power linear architectural fixtures rated at 42V DC. The adjustable output lets you match the exact voltage required by the fixture within the 21–42V range.

Will the ELG-100-42A work in very cold environments like outdoor winter installations?

Yes. The operating temperature range is -40°C to +90°C, so the driver is fully rated for cold-climate outdoor use. The metal case also acts as a heatsink to handle the upper end of that temperature range during high-ambient operation.

Can I use the ELG-100-42A to drive 42V LED modules in a retail display or illuminated sign?

Yes. The constant-current output with adjustable voltage trimming makes the ELG-100-42A well-suited for indoor or semi-outdoor illuminated signage using 42V LED modules. The IP65 rating also protects the driver from cleaning agents used in retail environments.
