Test conditions and notes9
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Current ripple is measured 60%~100% of maximum voltage under rated power delivery.
- 3. Derating may be needed under low input voltage. Please check the static characteristics for more details.
- 4. 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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 5. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
- 6. Suitable for indoor use or outdoor use without direct sunlight exposure. Please avoid immerse in the water over 30 minute.
- 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. This product is not intended for LED lighting luminaire applications in the EU and China.(In the EU and China the LPF/NPF/XLG/XLC/XLN series are recommended.)

FAQ
Can I use the LPC-20-700 for a 700mA LED downlight?
This model is suitable for a LED downlight when the LED module requires 700mA constant current and its total forward voltage is within 9-30V. With 21W output power, it is aimed at smaller downlight loads rather than larger multi-module fixtures. It should be matched to constant current LEDs, not constant voltage fixtures.
Is the LPC-20-700 suitable for compact signage lighting?
It can work for compact signage lighting if the LED assembly is designed for 700mA constant current and the full load falls inside the 9-30V CC range. Because this is a constant current driver, it is meant for current-regulated LED boards rather than constant voltage signage systems. Its 21W rating keeps it in the small-load category.
Can this driver power a small LED array with higher current demand?
Yes, provided the small LED array is built for 700mA constant current operation and needs between 9V and 30V across the full load. Compared with a lower-current driver, this model is better suited to arrays that need more drive current but still stay in a lower voltage range. It is not intended for constant voltage LED products.
How do I check whether my LEDs are compatible with the LPC-20-700?
Your LED load needs to require 700mA constant current, and the total forward voltage of the connected LEDs must fall within the 9-30V CC output range. The number of LEDs depends on the forward voltage of each LED, so compatibility cannot be reduced to one fixed LED count. This driver should not be used where the load expects constant voltage output.
How does the LPC-20-700 differ from the LPC-20-350 and LPC-35-700?
The LPC-20-700 delivers 700mA with a 9-30V CC range and 21W, while the LPC-20-350 delivers 350mA with a 9-48V range and 16.8W. Their over voltage protection points also differ (31.5-40.5V vs 50.4-60V). The LPC-35-700 belongs to a different series and is not covered by this datasheet, so please check its own spec sheet.
Is the LPC-20-700 appropriate for outdoor or washdown-prone locations?
It is fully encapsulated to IP67 level and is suitable for indoor use or outdoor use without direct sunlight exposure; immersion in water for over 30 minutes should be avoided. The working temperature is -30°C to +70°C, with load derating at higher ambient temperatures per the derating curve. Refer to the user manual for waterproof installation cautions.
