Test conditions and notes10

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. Please refer to "DRIVING METHODS OF LED MODULE".
4. This series meets the typical life expectancy of 30000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
5. 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.
6. 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)
7. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
8. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
9. 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).
10. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations but recommend to be used for commercial decoration/sign board/Luminaire lighting purpose.

FAQ

What are the main electrical ratings of the Mean Well SLD-80-56?

The SLD-80-56 is rated for 78.4W output with a 56V output voltage and 1.4A rated current. This model is designed as a linear LED driver with constant voltage plus constant current mode output. It is intended for applications that need those specific output values from a slim driver format.

What kind of LED applications is the SLD-80-56 best suited for?

This model is typically considered when a project needs a slim LED driver with 56V output and 1.4A rated current in a 78.4W class. Its linear housing design can be a practical fit where installation space is limited. Buyers usually compare it against other drivers by matching output voltage, current, and available space.

Does the Mean Well SLD-80-56 support dimming?

No. The listed dimming control for the SLD-80-56 is none. If dimming is required, this model should be compared against other LED drivers that explicitly include a dimming function.

What input range does the SLD-80-56 accept?

The product description lists a wide input range of 110-305VAC and also references 155-431VDC. That makes it suitable for buyers looking for broad input compatibility in commercial or industrial power environments. It also includes PFC according to the supplied description.

Is the SLD-80-56 suitable for demanding operating conditions?

The specified temperature range for this model is -20°C to +90°C (case temperature). That makes it a stronger candidate for environments where temperature tolerance matters, provided the rest of the application requirements also match the product's ratings. The unit also carries a 3-year warranty.
