Onboard 5V Fan Port
Fan Port Description
- Port Feature: This 5V fan port is designed as "Always On". It is defined as follows: once the main control board is powered on, the port continuously outputs 5V voltage, and the fan will start running continuously.
- Control Method: This port is not controlled by software and does not support intelligent start/stop functions based on temperature changes. It only provides basic cooling.
- Electrical Parameters: The current capability of this 5V output is directly related to your power input specifications:
- When using a 24V power supply, it can provide approximately 1A of current.
- When using a 12V power supply, it can provide approximately 0.5A of current.
- Therefore, the actual load capacity of the 5V output depends on the power solution you adopt.
- Terminal Specification: Please use a
ZH1.5-2Pterminal to connect the fan. The specific wiring method is shown in the image below.
