Over Voltage Protection(OVP)
⚫ Software over-voltage protection: when the over-voltage protection is
enabled, the voltage at the power output terminal is limited to the value set
by the over voltage protection. If the over-voltage protection is triggered,
the output will immediately be switched off and the LCD display will show
.
⚫ Hardware over-voltage protection: when the over-voltage protection is
disabled, the maximum input voltage of the power supply is limited to about
120% of the present voltage range. If the hardware over-voltage protection
is triggered, the output will be immediately switched off and the LCD
display will show . To avoid damage to the internal elements of the
product, please avoid that the external voltage loaded on the output
terminal is over 120% of the rated voltage.
⚫ Clear OVP: When the power supply occurs OVP, firstly cut off the DUT.
