The IT8500+ series electronic load supports the following protection functions: overvoltage protection (OVP), overcurrent protection (OCP), overpower protection (OPP), and overtemperature protection (OTP). If any of the protections are activated, the electronic load enters the corresponding self-protection mode, such as overtemperature protection. The load will then generate an alarm and the input will automatically switch to the OFF state. Finally, the VFD will display the OTP. The customer can clear the protection by pressing any button on the front panel.
