CN DC 12V 30A 400W Power Supply 350W 300W 250W 200 Transformer / 24V 36V LED Driver Adapter For 110-220 Source Adapter ,Applications Widely

We encourage everyone to use 220 because using 110 will cause the power supply to lose 20% of its power. When using power for a long time, do not exceed 80% of the maximum power. The conversion for current is: power (W)/voltage (V) = current (A). For example: 60W/12V-5A. The power is less than 250W and there is no fan for heat dissipation. Due to the low power and very small amount of heat generated, the unit is designed to have open holes for heat dissipation.
