ENABLING / DISABLING OVER VOLTAGE PROTECTION
The user can enable or disable the OVP circuit by pressing the "OVP ON/OFF (2)" key. When it is enabled
the OVP enunciator is on.
When the VFD displays “OVER VOLTAGE”, the over voltage protection circuit has been activated and the
output is disabled. To reset, press the "CLEAR (RESET)" key. To turn the output on again, press the "OUT
ON/OFF (1)” key.
<NOTES:>
1. Remote sensing, take into consideration the voltage drop across the load leads since the threshold
measurement is t
aken at the output.
3. In inductive load applications, a high-surge voltage would enable the OVP circuit and disable the output.
3. Also note the programming resolution and programming accuracy specifications
4. When the OVP ci
rcuit is disabled, the threshold voltage becomes invalid.
OVER CURRENT PROTECTION
The power supply has an over current protection (OCP) feature to guard the supply against current overdrawn.
If the OCP feature is enabled and the supply switches to CC mode, the OCP circuit is triggered and the output
is disabled. The OCP threshold is set by the value of the current limit.
