DC-DC Boost Converter 3.7V-5V to 280v-350V 400V adjustable voltage regulator Power supply Module FOR Capacitor charging Control solenoid valve

The capacitor charged and the control solenoid valve can be activated.

Input dc 3.7v~5v output 300v~350v .

Charge 450v 330uf Capacitor Within 2 seconds (guaranteed current) The module works intermittently and cannot work continuously. If continuous operation is required, please make the booster tube passive or forced to dissipate heat.

The boost must be added with a capacitor. After charging to the specified voltage value, the charging is stopped. The no-load does not output voltage. After the charging stops automatically, the current is 0. There is no power loss. The capacitor can be re-energized after it is completely discharged.

Note: High current power equipment, charging does not last long. For capacitors above 330 UF, it is necessary to pay attention to heat dissipation, and it cannot be used for continuous load.
