Frequently Asked Questions
Can I use the ELG-240-48B to power a large 48V LED strip installation?
Yes. At 240W and 48V, this driver can power up to 240W worth of 48V LED strip. For example, a strip rated at 20W per meter would allow up to 12 meters per driver. Always check your strip's rated power per meter and keep total load at or below 240W.
Is the ELG-240-48B suitable for outdoor LED signage?
Yes. The ELG-240-48B carries an IP67 rating, meaning it is fully sealed against dust ingress and can withstand temporary submersion in water. This makes it suitable for outdoor LED signage cabinets and exposed architectural lighting fixtures.
Can I dim the ELG-240-48B with a 0–10V dimming signal?
Yes. The B-type suffix indicates three-in-one dimming compatibility, which includes 0–10V, PWM signal, and resistance dimming methods. The output current is continuously adjustable across the CC voltage range of 24–48V.
Can the ELG-240-48B be used in cold-storage or outdoor enclosures exposed to freezing temperatures?
Yes. The operating temperature range is -40°C to +90°C, so this driver functions reliably in cold environments such as outdoor cabinets in winter climates or refrigerated display cases.
Is the ELG-240-48B appropriate for commercial LED lighting projects requiring dimming control?
Yes. With 240W output at 48V and three-in-one dimming, this driver is well suited for commercial cove lighting, retail display illumination, and architectural LED installations where a 0–10V building automation signal or PWM controller is used.
Can I run a 48V LED driver in parallel with another ELG-240-48B to expand capacity?
The ELG-240-48B can be operated in parallel for increased current output when units are wired in a shared load configuration; consult the datasheet for parallel operating instructions. Each unit provides 5A at 48V, so two units together can supply up to 10A.
How does the ELG-240-48B differ from other ELG-240-48 variants?
The ELG series at 240W 48V includes variants without dimming (ELG-240-48), with output adjust only (ELG-240-48A), with three-in-one dimming (ELG-240-48B), with D2 digital dimming (ELG-240-48D2), and with DALI dimming (ELG-240-48DA/DA-3Y). All share 240W, 48V, and 5A output; the suffix indicates the dimming interface only.
