*OVP (Over Voltage Protection): OVP prevents the damaging impact of excessive output voltage by shutting down the power unit.
*UVP (Under Voltage Protection): UVP ensures a constant flow of power to keep your components at their max performance.
*OPP (Over Power Protection): OPP safeguards the power supply from any overload, preventing over exposure to extreme power conditions.
*OTP (Over Temperature Protection): OTP automatically shuts down the power supply if the system overheats. This helps protect the power supply duration from any possible damage.
*SCP (Short Circuit Protection): SCP prevents any “rush back” of voltage that may cause harm to the power supply and other components.
