Overview

PWM-90-24 is the 24V output model of this series: rated current 3.75A, rated power 90W, typical efficiency 90.5%.

PWM-90 series is a 90W LED AC/DC LED driver featuring the constant voltage mode with PWM style output, which is able to maintain the brightness homogeneity when driving all kinds of LED strips.PWM-90 operates from 90～305VAC and offers models with different rated voltage ranging between 12V and 48V. Thanks to the high efficiency up to 90.5%, with the fanless design, the entire series is able to operate for -40℃ ~ +85℃ case temperature under free air convection.

Test conditions and notes9

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 first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
4. 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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
5. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
6. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
7. 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).
8. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
9. Based on IEC 62386-101/102 DALI power on timing and interruption regulations, the set up time needs to test with a DALI controller which can support for DALI power on function, otherwise the set up time will be higher than 0.5 second for DA-2 type.

FAQ

Can I use the PWM-90-24 to drive 24V LED strips in an outdoor landscape lighting project?

Yes. The IP67 waterproof rating makes the PWM-90-24 suitable for outdoor landscape lighting where the driver may be exposed to rain or moisture. It outputs 24V at up to 3.75A (90W), enough to run a substantial length of 24V strip lighting.

What dimming methods does the PWM-90-24 support?

The PWM-90-24 includes built-in 3-in-1 dimming, which accepts 0–10V analog, 10V PWM signal, and resistance dimming inputs. This allows it to work with a broad range of compatible dimmers and control systems without needing an external dimming interface.

Is the PWM-90-24 a good choice for powering 24V LED strips in illuminated outdoor signage?

Yes. At 90W and 24V, it provides enough power for medium-scale 24V LED strip signage, and the IP67 rating ensures the driver can be mounted in locations exposed to weather. The wide 90–305VAC input also makes it easy to deploy in varied electrical environments.

How many meters of 24V LED strip can the PWM-90-24 power?

The driver delivers up to 90W at 24V. If your 24V strip is rated at 14.4W per meter, you could power approximately 6.25 meters (90W ÷ 14.4W/m ≈ 6.25m). For long-term continuous use, limit load to 80% capacity (72W) — about 5 meters at that strip rating. Always check your strip's rated power per meter.

Can the PWM-90-24 be used for 24V LED strip lighting inside a cold-storage facility?

Yes. The operating temperature range of -40°C to +85°C (Tcase) allows this driver to function reliably in cold-storage and refrigerated environments. The fully sealed IP67 enclosure also protects against moisture and condensation common in those settings.

Does the PWM-90-24 work with a standard 0–10V lighting control system?

Yes. The 3-in-1 dimming feature includes 0–10V analog dimming as one of its supported methods, making the PWM-90-24 directly compatible with 0–10V lighting controllers commonly used in commercial and hospitality settings.
