Frequently Asked Questions
Can the ELG-100-C1050A drive LED downlights where the output current needs to be trimmed on-site?
Yes. The 'A' suffix indicates an analog output-adjustment interface that lets installers trim the constant current output from the panel without replacing the driver. The driver delivers up to 1050mA across a CC voltage range of 48–95V.
Is the ELG-100-C1050A rated for damp or outdoor LED sign cabinet use?
The ELG-100-C1050A carries an IP65 water-resistant rating, which protects against dust ingress and low-pressure water jets. It is suitable for damp locations and sign cabinets, but not for full immersion or high-pressure wash-down environments.
Can I use this driver for LED retail display lighting that requires periodic brightness adjustment?
Yes. The adjustable output feature of the ELG-100-C1050A makes it practical for retail displays where a designer may need to fine-tune light levels after installation. It operates in constant current mode at 1050mA output.
What LED string voltages work with the ELG-100-C1050A?
The constant current output voltage range is 48–95V. Series-connected LED strings whose combined forward voltage falls within this window are compatible; the actual number of LEDs in series depends on each LED's forward voltage.
Does the ELG-100-C1050A work on a wide range of global AC supplies?
Yes. It accepts 100–305VAC, covering 100V Japanese, 120V North American, 230V European, and 277V US commercial supplies without any hardware reconfiguration.
How does the ELG-100-C1050A compare to the non-adjustable ELG-100-C1050?
Both are 99.75W constant-current drivers at 1050mA with a 48–95V CC range. The primary difference is that the ELG-100-C1050A adds an output-adjustment (trim) interface, while the base model does not. The ELG-100-C1050 is rated IP67 waterproof; the C1050A is rated IP65 water-resistant.
