Overview :

The power supply was designed for LED display :,small size, high efficiency, stability, and reliability. Power supply has input undervoltage, output current limiting, output short circuit protection. Power supply will apply with high rectification which greatly improves the power efficiency,can reach 87.0% above, saving energy consumption.



Note 1: Please add the new requirement when the power supply will be used for high humidity condition.


Note 2:Meanings of rated input voltage and the input voltage range: the rated input voltage is the international general appellation, the highest voltage of rated input voltage float upwards 10%,is the input voltage upper limit, the maximum value, the minimum voltage of rated input voltage float downward 10%, is the input voltage lower limit, the minimum value. Rated input voltage range of 200-240 is corresponding to 180-264. The two terms are not contradictor, essence is consistent, uniform, only two different terms.



Note 3:Efficiency:Terminal output voltage multiplied by the output current, and then divided by the AC input voltage, divided by the AC input current, divided by the power factor: efficiency=terminal output voltage X output current / (the AC input voltage X AC input current X power factor).

Output Electrical Characteristics :


Note 3: Ripple & noise test: Ripple & noise bandwidth is set to 20MHz, use a 0.10uF ceramic capacitor in parallel with a 10.0uF electrolytic capacitor at output connector for ripple & noise measurements.

Note 4: The power delay time measured is when AC power on to 90% of specified output voltage observed on the channel.

Note 5: The hold-up time measured is when AC power off to 90% of specified output voltage observed on the channel.


Note 6: The rise time measured is when the output voltage rise from 10% to 90% of specified output Vout observed on the channel wave form.
