Frequently Asked Questions

Can the ELG-100-C1400DA be integrated into a DALI building management system for office LED downlights?

Yes. The ELG-100-C1400DA includes a native DALI interface, allowing it to be addressed and controlled individually by a DALI-compliant building management or lighting control system. It delivers a constant 1400mA at 100.8W, suitable for powering LED downlight modules in office environments. The IP67 waterproof enclosure provides flexibility in installation, including humid plenum spaces.

Is the ELG-100-C1400DA suitable for LED signage installations in a DALI-controlled environment?

Yes. The DALI interface on the ELG-100-C1400DA allows centralized control of LED signage brightness through a DALI network, which is useful in venues where multiple sign zones must be scheduled or dimmed independently. The driver is rated IP67 waterproof, supporting both indoor and semi-outdoor signage cabinet installations. Input accepts 100–305VAC, covering international mains voltages.

Can the ELG-100-C1400DA drive LED modules in a retrofit project where the existing control system uses DALI?

Yes, the ELG-100-C1400DA is designed for DALI-protocol dimming and is suitable for retrofit projects where the control infrastructure is already DALI-based. It supplies a constant 1400mA to the LED load and operates across a 35–72V output range. Verify that the LED module's forward voltage series string total falls within the 35–72V range before selecting this driver.

How does the DALI interface on the ELG-100-C1400DA differ from the dimming in the ELG-100-C1400B?

The ELG-100-C1400DA uses the DALI protocol exclusively, which supports individual addressing, group scenes, and scheduled dimming via a two-wire DALI bus, as used in sophisticated building management systems. The ELG-100-C1400B uses analog dimming methods (0–10V, PWM, resistance), which are simpler to wire but do not support DALI addressing. Both drivers share the same 100.8W, 1400mA, IP67 specification.

What LED string voltage range is compatible with the ELG-100-C1400DA?

The ELG-100-C1400DA operates in constant current mode with an output voltage compliance range of 35–72V. The LED string's total forward voltage — the sum of all series-connected LEDs' Vf values — must fall within this range for the driver to regulate correctly at 1400mA. The actual number of LEDs is not fixed and depends entirely on the Vf of the LEDs selected.

Can the ELG-100-C1400DA be installed in outdoor or wet-location LED fixtures?

Yes. The ELG-100-C1400DA is rated IP67, which means it is fully protected against dust and can withstand temporary immersion in water up to 1 meter, making it suitable for outdoor LED fixtures or wet-rated indoor locations. Its operating temperature range of -40°C to +90°C covers most outdoor environments. The wide 100–305VAC input accommodates international power grids.
