Power with set for output voltage

The utility model is suitable for a power technology improves the field, provides a power with set for output voltage, including the voltage input module, the input of the output linked switch moduleof voltage input module, voltage output module's input is connected to the output of switch module, the input of modulation voltage module is connected to voltage output module's output, the input ofvoltage output module's output connection control module, drive module's input is connected to control module's output, the input of drive module's output linked switch module, wire jumper cap throughadjustment modulation voltage module changes the different voltage of output. Modulation voltage module has been add for guaranteeing under the output circumstances unchangeable basically that the voltage of output can be through the nimble settlement of wire jumper, the product can be produced greatly in batches, the stability that can improve production, reduction line changing cost and inventory risk.
