1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ 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. Line regulation is measured from low line to high line at rated load. 5. Load regulation is measured from 0% to 100% rated load. 6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time. | ||||||||||||||||

Power Supply FAQ
How do you select suitable MeanWell power supplies and 12v 30a power supply?
A. Select suitable wattage based on customer’s system requirements
and application methods. Must also take excess power and driving
method into consideration.12v 30a power supply
B. Based on LED power supply’s operating environment select
suitable IP level and mechanical type (metal enclosure, plastic
enclosure, and open frame PCB) for that environment.
C. Is PFC function required or not? Single stage PFC is only
suitable for LED load. Dual stage PFC is suitable for general
applications.12v 30a power supply.12v 30a power supply
D. If LED system is based on direct drive, units with adjustable
voltage and current should be considered for flexibility in
changing voltage/current levels. Dimming function may also come in
handy when LED brightness control is preferred.
