Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
3. Length of set up time is measured at cold first start. Turning ON/OFF the driver may lead to increase of the set up time.
4. Aux. 12V will be damaged with short circuit; It will not be available with dimming off or output no load condition.
5. The driver 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.
6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
7. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.

FAQ

Can I use the IDLV-45-12 for 12V LED strip lighting in shelving, coves, or display accents?

Yes, this is a 12V PWM-output LED driver with 36W rated power and 3A rated current. It fits 12V LED strip lighting applications where the total strip load stays within 36W.

Is the IDLV-45-12 suitable for 12V LED signage or light box lighting?

It can be used for 12V LED signage or light box applications if the lighting load is designed for a 12V supply and does not exceed 36W. The 3A rated current supports moderate 12V signage loads within that power limit.

Can this driver power 12V linear lighting for cabinets or retail displays?

Yes, it has a 12V output and can support cabinet, shelf, or retail display lighting that stays within 36W. Buyers should match the fixture or strip voltage to 12V and keep the total load at or below 3A.

Is the IDLV-45-12 a good fit for short-run 12V LED strip projects?

Yes, this model is better suited to shorter or lower-power 12V strip runs because its rated output is 36W. It has a 12V output, so the strip or fixture should be designed for 12V operation.

How much 12V LED strip can the IDLV-45-12 run?

The maximum strip load is 36W, so estimated strip length is 36W divided by your strip's rated power per meter. For example, the formula is 36 ÷ watts per meter = maximum meters, and you should check your strip rated power per meter before sizing.

Can the IDLV-45-12 be used outdoors or in wet locations?

The provided specifications do not list an IP rating, so this product should not be treated as wet-location or outdoor-rated based on the available data alone. Its working case temperature (Tcase) range is -20°C to +85°C, but temperature range is not the same as water ingress protection.

How does the IDLV-45-12 compare with the other 12V IDLV series models?

This spec sheet covers only the IDLV-45 series, so ratings of other IDLV series are not confirmed here. The IDLV-45-12 delivers 36W at 3A, and its A-Type version adds a nominal 12V auxiliary output rated at 50mA.
