Frequently Asked Questions
Can I use the ELG-150-12B to power 12V LED strip lighting in an outdoor sign cabinet?
Yes. The ELG-150-12B is rated IP67, meaning it is fully sealed against dust and can withstand temporary submersion, so it is suitable for outdoor sign cabinets exposed to rain or wash-down environments. Its 12V output matches standard 12V LED strip tape directly.
Is the ELG-150-12B suitable for powering LED strips mounted on a building facade exposed to rain?
Yes. The IP67 rating certifies this driver against water ingress from rain and splashing, and the metal case is designed for outdoor installation. The operating temperature range of -40°C to +90°C also accommodates most outdoor climates.
How many meters of 12V LED strip can the ELG-150-12B power?
The ELG-150-12B delivers up to 120W at 12V. Dividing 120W by your strip's rated power per meter gives the maximum run length — for example, a 14.4 W/m strip yields 120 ÷ 14.4 ≈ 8.3 m per driver. Always check your strip's rated power per meter and derate to 80% for continuous operation, which would give roughly 6.6 m for that example.
Can I use the ELG-150-12B to dim LED strips in a retail display?
Yes. The 'B' suffix indicates built-in three-in-one dimming: it accepts a 1–10V analog signal, a PWM control signal, or a resistance input, making it compatible with most dimming controllers used in retail display lighting. The dimming range runs down to the minimum the connected controller can produce within the 6–12V CC voltage range.
Can the ELG-150-12B be used to drive LED lighting inside a food processing area that gets hosed down?
The IP67 rating covers temporary water immersion up to 1 m, which is suitable for hose-down environments common in food processing facilities. Verify that the specific installation enclosure and wiring also meet the required ingress protection for your local safety code.
Is the ELG-150-12B a good fit for architectural LED cove lighting in a hotel lobby?
Yes. At 120W and 12V it can serve multiple short runs of 12V cove LED strip, and the built-in 3-in-1 dimming allows smooth tuning from a building management system or standard 0–10V dimmer. The metal enclosure is compact enough (219 × 63 × 35.5 mm) to fit within a standard cove cavity.
How does the ELG-150-12B compare to other 12V variants in the ELG-150 series?
The ELG-150-12 series at 12V includes several control variants sharing the same 120W / 10A output: the base model (no dimming), the A variant (built-in potentiometer), the B variant (3-in-1 dimming), the AB variant (potentiometer + 3-in-1 dimming), the D2 variant (150W, DALI-2 / push-dimming), and the DA variant (DALI dimming). Choose based on your dimming protocol; all share the same enclosure and IP67 rating.
