Test conditions and notes8
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25β of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. Please refer to "DRIVING METHODS OF LED MODULE".
- 5. Derating may be needed under low input voltages. Please check the static characteristics for more details.
- 6. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
- 7. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.
- 8. Refer to warranty statement.

FAQ
Can the ELG-150-12AB be used to drive 12V LED strips in an outdoor retail sign cabinet?
The ELG-150-12AB is rated IP65, which protects against water jets and dust but is not submersion-rated. It is appropriate for sign cabinets that shield the driver from direct rain exposure. For unprotected outdoor mounting where direct rain contact is likely, consider the IP67-rated ELG-150-12B instead.
Is the ELG-150-12AB appropriate for a 12V LED strip installation in a hotel corridor with a building-automation dimming system?
Yes. The AB suffix means the driver supports both adjustable output current and 3-in-1 dimming (1β10V, PWM, and resistance). This covers the range of control interfaces used in building-automation and hospitality environments, allowing integration with scene controllers or BMS systems.
How many meters of 12V LED strip can the ELG-150-12AB power?
The driver outputs 120W at 10A. For a 12V strip rated at 14.4 W/m, you can run approximately 8.3 m per driver (120 W Γ· 14.4 W/m). For a denser strip at 24 W/m, that reduces to about 5 m. Always verify the strip's rated power per meter and allow a 10β20% safety margin.
Can the ELG-150-12AB power 12V LED tape used in cove lighting for a restaurant interior?
Yes. With 120W of output at 12V and support for continuous dimming via the built-in 3-in-1 interface, this driver suits restaurant cove lighting where tunable ambient levels are needed for different service periods. The adjustable current also allows fine brightness calibration during the fit-out.
Is the ELG-150-12AB suitable for 12V LED strip lighting in a residential bathroom with steam or humidity?
The IP65 rating provides protection against water spray, which covers steam and humidity in bathroom environments. Avoid direct water contact on the driver body. For shower niches or areas with direct water splash, the IP67 variant would offer additional protection.
Can this driver be used in a commercial office fit-out with 0β10V dimmers controlling 12V LED strip ceiling lights?
Yes. The AB model includes 1β10V dimming support as part of its 3-in-1 interface, which is directly compatible with standard 0β10V commercial dimmers. At 120W and 10A, it provides sufficient power for multi-meter runs of 12V ceiling strip in open-plan office layouts.
