Feature:1. The DC output voltage/current is related to the output of the transformer, the DC output voltage (no load) = AC input voltage x 1.422. Wide voltage range input, with overload, short circuit, and over temperature protection3. AC input voltage should not be greater than 25V, if you want to input a higher AC voltage, use a higher voltage capacitor4. Use of original accessories not only guarantees safety and quality, but also guarantees a good signaltonoise ratio of the whole machine5. A power board that converts a single power supply into a DC single power output, the maximum DC output can support DC10A or moreSpecification:Item Type: Rectifier Filter Power BoardThe Highest AC Voltage Input: Single 18VBoard Size: Approx. 50x25mm / 2.0x1.0in(8a Rectifier Bridge) Filter Capacitor: Original Ruby 3300uf/25V(Diameter Approx. 18mm/0.71in, Height Approx. 20mm/0.79in, Foot Pitch Approx. 7.5mm/0.3in) +0.1uf/100V (Foot Pitch Approx. 5.0mm/0.2in).Package List:1 x Rectifier Filter Power Board
