Frequently Asked Questions
Can I use the ELG-100-C700 to drive LED downlights in a commercial office fit-out?
Yes. The ELG-100-C700 is a constant current driver rated at 700mA with a CC output voltage range of 71–143V, which covers many multi-LED downlight modules designed for series operation. At 100.1W it provides enough power for a single high-wattage luminaire or a compact array of lower-wattage LED downlights whose combined forward voltage falls within the operating window.
Is this driver appropriate for LED channel-letter or illuminated signage applications?
Yes. The 71–143V constant current range accommodates medium-to-long series strings of LED signage modules operating at 700mA. The IP67 rating means the driver can be housed in an outdoor signage cabinet exposed to rain, and the -40°C to +90°C operating range covers most outdoor installation conditions.
Can the ELG-100-C700 be used in a wet or outdoor environment without an additional enclosure?
Yes. The ELG-100-C700 has an IP67 waterproof rating, so it is fully protected against dust ingress and temporary submersion. It can be mounted directly on an outdoor structure or inside a non-sealed signage cabinet. The metal case also provides mechanical protection in industrial or harsh environments.
How many LEDs can the ELG-100-C700 support in a constant current string?
The total forward voltage of the LED string must fall between 71V and 143V. The actual number of LEDs depends on each LED's forward voltage — there is no fixed count. For example, LEDs with higher forward voltages will result in fewer devices per string compared to those with lower forward voltages.
What is the difference between the ELG-100-C700 and the ELG-100-C500DA?
The ELG-100-C700 delivers 700mA at a CC range of 71–143V with no built-in dimming, while the ELG-100-C500DA outputs 500mA at a CC range of 100–200V and includes DALI dimming. Both are IP67 rated and rated near 100W. Select based on whether your LED load requires 700mA or 500mA drive current and whether DALI control integration is needed.
Does the ELG-100-C700 operate as a constant current or constant voltage driver?
The ELG-100-C700 operates exclusively in constant current mode, maintaining a fixed 700mA output regardless of load voltage variations within the 71–143V range. This is distinct from constant voltage drivers and is required for LED loads that must be current-regulated rather than voltage-regulated.
