12V 300mA power supply module
Say goodbye to dealing with bulky power converters; introducing a convenient and compact way to power up your hobbyist projects! Our 12V 300mA Power Supply Module is a perfect fit for those times when larger power consumption isn't necessary.
A DC power supply module converts AC power from a standard outlet into a stable DC power source. This regulated direct current is then used to power a device, module, or component. DC power supplies come in varying levels of input and output voltage, output current, and power rating.
The main advantage of the 12V 300mA power supply module is greater efficiency (up to 96%) and lower heat generation than linear regulators because the switching transistor dissipates little power when acting as a switch.
Other advantages include smaller size and lighter weight from the elimination of heavy and expensive line-frequency transformers. Standby power loss is often much less than transformers.
