Frequently Asked Questions
What makes the ELG-150-12B-3Y different from the standard ELG-150-12B?
The ELG-150-12B-3Y adds a 3-conductor input configuration compared to the standard ELG-150-12B, which is useful for installations requiring a separate earth/ground wire on the input side. Both share the same 120W, 12V, 10A output, IP67 rating, and 3-in-1 dimming capability.
Can the ELG-150-12B-3Y power 12V LED strips in an outdoor landscape lighting system?
Yes. With an IP67 waterproof rating the driver can be installed in outdoor junction boxes or buried enclosures appropriate for landscape use. It supplies 120W at 12V, enough to drive multiple landscape LED strip runs from one supply.
How much 12V LED strip can I run from the ELG-150-12B-3Y?
The driver provides 120W at 12V. For a 9.6 W/m strip, that allows 120 ÷ 9.6 = 12.5 m at full load; apply an 80% derating for continuous use, giving about 10 m. Always verify your strip's rated power per meter before sizing.
Is the ELG-150-12B-3Y suitable for powering LED channel letters on an outdoor sign?
Yes. The IP67 waterproof enclosure protects against rain and outdoor humidity, and 12V is the standard voltage for LED modules used in illuminated channel letters. The 3-in-1 dimming allows brightness adjustment if needed for daytime/nighttime operation.
Can the ELG-150-12B-3Y operate in a cold storage room that drops below freezing?
Yes. The operating temperature range is -40°C to +90°C, so it can function in cold storage environments well below 0°C without issue.
Can I use the ELG-150-12B-3Y with a 0–10V building automation dimming system?
Yes. The 3-in-1 dimming on this driver accepts a 1–10V analog signal as one of its three control methods, which is directly compatible with standard 0–10V building automation and lighting control systems.
