What is VCC on Power Supply?
VCC or Voltage Common Collector is a high current output port on a power supply unit. It is commonly used to supply power to devices that require large amounts of current such as motors, solenoids, and actuators.
Uses of VCC in Power Supply
- Providing a steady source of power to multiple devices simultaneously by using voltage regulators.
- Delivering power to a single device from a single source that requires a large current.
- Serving as a source of power when using a transformer to increase voltage to a higher level.
Advantages of VCC on Power Supply
- VCC acts as a single connection point to supply high current devices, thereby reducing the amount of circuitry required.
- It is easy to install and configure.
- Makes it easier to manage power needs when devices require a steady supply of power.
Limitations of VCC on Power Supply
- It is not possible to use VCC on devices that require isolated power.
- Care must be taken when using VCC, as some devices may be damaged if the current exceeds the device’s rating.
- VCC does not offer protection from electrical noise or surges, as is often found in a commercial grade power supply.
VCC is an essential component of a power supply, as it provides a single source for delivering high current to a wide variety of devices. It is important to understand the limitations of VCC when using it to ensure that it is used safely and effectively.
