Frequently Asked Questions
Can the ELG-100-C700B be used to drive dimmable LED downlights in a hospitality or retail setting?
Yes. The ELG-100-C700B is a dimmable constant current driver delivering 700mA across a 71–143V CC output range, which suits many high-power LED downlight modules. The dimming input allows brightness control from a compatible dimmer or lighting controller, and the IP67 rating means the driver can be installed in above-ceiling spaces or other locations where moisture may be present.
Is the ELG-100-C700B rated for outdoor or wet-area installation?
Yes. The IP67 waterproof rating protects the driver against dust and temporary water immersion, making it suitable for outdoor LED signage housings, canopy lighting, or other exposed locations. The operating temperature of -40°C to +90°C means it can also handle extreme cold or high-ambient-temperature installations.
How does the ELG-100-C700B differ from the ELG-100-C700AB?
The ELG-100-C700B provides dimming functionality only, while the ELG-100-C700AB adds an output current adjustment feature on top of dimming. The ELG-100-C700B is rated IP67 (waterproof) compared to the IP65 of the C700AB. Both share the same 100.1W, 700mA, and 71–143V CC specifications.
Can the ELG-100-C700B drive a series LED string for illuminated outdoor signage?
Yes. The 71–143V constant current operating range accommodates outdoor LED signage strings that require a stable 700mA drive current. Combined with IP67 waterproofing, the driver can be housed directly in an outdoor sign cabinet without a separate sealed enclosure.
How do I determine how many LEDs I can connect in series to the ELG-100-C700B?
Add up the forward voltages of the LEDs you plan to connect in series; the total must be between 71V and 143V to stay within the CC operating range. The exact number of LEDs varies depending on the forward voltage specification of the particular LED you are using.
