1.Multiple protection mechanisms
Overvoltage protection(OVP):When the output voltage exceeds 6.6V±1%,the output is automatically shut down and latched,and manual reset or remote signal unlocking is required.
Overcurrent protection(OCP):When the output current exceeds 110%of the rated value,it enters the hiccup mode and automatically recovers after the fault is eliminated.
Short circuit protection(SCP):When the output is short-circuited,the current is limited to<120%of the rated current,and the power supply is restored immediately after the short circuit is removed.
Overtemperature protection(OTP):When the internal temperature exceeds 110℃,the power supply is turned off to prevent damage,and it automatically restarts after the temperature drops to 90℃.
Input undervoltage/overvoltage protection:When the input voltage is lower than 80VAC or higher than 275VAC,the power supply is turned off and an alarm is issued.
