Frequently Asked Questions
Can the ELG-100-C1400B be used to drive LED downlights in a building automation system with 0-10V dimming?
Yes, the ELG-100-C1400B supports external dimming control via its 'B' dimming interface, which is compatible with 0–10V, PWM, and resistance dimming signals, allowing integration with building automation lighting control systems. It delivers a constant 1400mA at up to 100.8W and operates across a 35–72V output range suited to medium-power LED downlight modules. The IP67 waterproof rating also allows flexible installation locations.
Is the ELG-100-C1400B suitable for outdoor LED signage that requires dimming control?
Yes. The ELG-100-C1400B is rated IP67, meaning it is fully protected against dust and temporary water immersion up to 1 meter, making it a strong choice for outdoor LED signage cabinets exposed to rain or wash-down cleaning. Its external dimming input allows sign brightness to be adjusted by a controller. The driver accepts 100–305VAC input, covering both North American and international mains supplies.
Can I install the ELG-100-C1400B in an outdoor LED fixture that may be exposed to rain?
Yes. The ELG-100-C1400B has an IP67 waterproof rating, which protects it against complete dust ingress and temporary immersion in water up to 1 meter for 30 minutes. This makes it suitable for outdoor LED fixture installations that may be exposed to rain or moisture. Its operating temperature range of -40°C to +90°C also supports a broad range of outdoor climates.
How does the ELG-100-C1400B maintain consistent LED brightness as temperature changes?
As a constant current driver, the ELG-100-C1400B regulates its output to a fixed 1400mA regardless of the LED string's forward voltage, which shifts with temperature. This keeps drive current — and therefore light output — stable across the operating temperature range of -40°C to +90°C. The driver's wide 35–72V compliance range allows it to track the LED forward voltage drift without losing regulation.
What LED load voltage range is compatible with the ELG-100-C1400B?
The ELG-100-C1400B operates in constant current mode with an output voltage compliance range of 35–72V. LED strings whose combined forward voltage falls within this range can be driven at the rated 1400mA. The actual number of LEDs that fit depends on the individual LED's forward voltage; there is no single fixed count.
How does the ELG-100-C1400B differ from the ELG-100-C1400DA in dimming capability?
The ELG-100-C1400B supports PWM, 0–10V, and resistance-based dimming through its 'B' dimming interface, which is common in commercial lighting controls. The ELG-100-C1400DA instead uses the DALI (Digital Addressable Lighting Interface) protocol, which is suited to DALI-based building management systems and allows individual addressable control. Both share the same 100.8W, 1400mA output rating and IP67 waterproof enclosure.
