Frequently Asked Questions
Is the ELG-75-42A suitable for outdoor LED lighting installations?
The ELG-75-42A is rated IP65, which means it is protected against dust and low-pressure water jets from any direction. It is suitable for rain-exposed outdoor fixtures and sign cabinets but is not intended for temporary immersion—choose the IP67-rated variants for submersion-risk locations.
How many meters of 42V LED strip can the ELG-75-42A drive?
The ELG-75-42A delivers 75.6W at 42V. For a 10 W/m strip, the maximum is approximately 7.5 meters; for an 8 W/m strip, about 9.5 meters. Divide 75.6W by your strip's rated power per meter and reduce by 20% to account for thermal derating and efficiency losses.
Can I adjust the output current of the ELG-75-42A for different LED loads?
Yes. The 'A' suffix indicates a built-in potentiometer that allows the output to be trimmed within the CC voltage range of 21–42V. This is useful for fine-tuning the current to match a specific LED load or to compensate for wiring resistance in longer runs.
Is the ELG-75-42A a good fit for powering 42V LED strips in a retail display case?
Yes. The adjustable output and 75.6W at 42V make the ELG-75-42A well suited to retail display lighting where precise brightness control without a separate dimmer is needed. The wide 100–305VAC input range supports both 120V and 230V installations.
Can the ELG-75-42A be used in a cold-climate outdoor application?
Yes. The ELG-75-42A operates from -40°C to +85°C, making it suitable for outdoor signage and landscape lighting in cold regions. Its IP65 rating handles rain and dust exposure typical of outdoor enclosures.
How does the ELG-75-42A differ from the ELG-75-42B?
The ELG-75-42A ('A' suffix) adds a potentiometer for analog output adjustment and is rated IP65. The ELG-75-42B ('B' suffix) adds 3-in-1 dimming (10V, PWM, resistance) for remote control and is rated IP67 for higher water ingress protection. Both deliver 75.6W at 42V with 1.8A output.
