Frequently Asked Questions
Can I use the ELG-75-C350B to drive LED downlights in a commercial lighting installation?
Yes. The ELG-75-C350B operates as a constant current driver at 350mA, which is a standard current level for many LED downlight modules. Its 74.9W output and CC voltage range of 107–214V allows it to support series strings of LEDs whose combined forward voltage falls within that range. The IP67 rating also makes it suitable for recessed or damp-location downlight housings.
Is the ELG-75-C350B suitable for outdoor LED signage modules?
Yes. With an IP67 waterproof rating and an operating temperature range of -40°C to +85°C, the ELG-75-C350B can be installed in exposed outdoor environments. It accepts 100–305VAC input, making it compatible with worldwide mains voltages commonly used in outdoor signage cabinets.
Can I use this driver for a small LED array in a cold storage or freezer environment?
Yes. The ELG-75-C350B is rated for operation down to -40°C, so it is appropriate for cold storage, freezer rooms, or outdoor installations in cold climates. The IP67 sealed metal enclosure also protects against condensation and moisture ingress.
Does the ELG-75-C350B support dimming, and what dimming methods are available?
The B-suffix variant supports both PWM and resistance dimming via a three-in-one dimming interface. This allows the driver to be integrated into lighting control systems that use either PWM signals or a simple potentiometer for brightness adjustment. Output current can be dimmed down from the full 350mA level.
How many LEDs can the ELG-75-C350B drive in series?
The CC voltage range is 107–214V, so the number of LEDs in a series string depends on each LED's forward voltage. Divide the usable voltage window by the forward voltage of your specific LED to determine how many can be connected in series. Do not pair with a string whose total forward voltage falls outside the 107–214V range.
What certifications does the ELG-75-C350B carry?
The ELG-75-C350B holds c_BSI, CB, CCC, CE, EAC, ENEC, c_RCM, and UL certifications. This broad certification coverage makes it suitable for projects requiring compliance with North American, European, Australian, and Chinese market requirements.
How does the ELG-75-C350B compare to the ELG-75-C350 and ELG-75-C350D2 within the same current family?
Within the ELG-75 350mA family, the ELG-75-C350 (74.9W, 224V max) has no dimming, the ELG-75-C350B (74.9W, 224V max) adds three-in-one PWM/resistance dimming, the ELG-75-C350D2 (75W, 214V max) uses a different D2 dimming interface, and the ELG-75-C350DA (74.9W, 224V max) adds DALI dimming. All share the same 350mA constant current output; the variants differ only in dimming method.
