In+: Input positive; - In-: Input negative; - Out+: Output positive; - Out-: Output negative; - Input voltage: 5~25V; - Output voltage: 0.5~25V(Adjustable); - IN/OUT Power : 30W(MAX); - Rated current: Max. 2A; - Note: This module don't have reverse protection if you connect reversely it will be burned. Please pay more attention. When the output is in shot the output will be automatically stopped. So you put out the enable interface cap and then insert it. The module will become normal. When the module starts or the load is off it will appeared easily that the temperate output voltage will be more than the preset voltage. So the module is not suitable for the device which is sensitive to voltage.
