The input adopts replaceable fuse to protect the power supply and equipment The whole electrolytic board adopts patch, low resistance, high frequency capacitor, so that the ripple is reduced to the freezing point Constant voltage, constant current, undervoltage protection (MPPT is more suitable for solar charging)Output error indicator light, which lights up when the output voltage drift is too serious, short circuit and other faults The heat dissipation effect of the oxidized heat sink is that of the natural aluminum sheet The inductor adopts iron silicon aluminum, which generates less heat Electrical parameters: Input voltage: DC5-32V, recommended voltage is above 10V Output voltage: DC1V-30V continuously adjustable Output current: 10A (MAX), long-term within 7A Output power: long-term 80W, 130W, please strengthen heat dissipation if it exceeds 80W Output ripple: 50mV (12V to 12V, measured) Input reverse connection protection: No, if necessary, please connect a Schottky diode in series at the input end Output backflow protection: No, if used for battery charging or the load is a self- load, please connect a Schottky diode in series at the output end Size: 77.6x46.5x15mm Short circuit protection:Yes The product appearance and printed words depending on the batch, but this does not affect use. Colour:As Shown Material:PCB Package Contents: 1 * Solar Car Voltage Regulator Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
