Comprehensive Protection Features
The power supply offers Over Voltage Protection (OVP) and Over Current Protection (OCP) settings, activated by pressing "V" and "A" for long durations. When enabled, these features trigger an alarm and shut off the output to safeguard connected equipment. The built-in intelligent fan adjusts based on system conditions, while Over Temperature Protection (OTP) engages when the instrument overheats, ensuring system longevity.
