Power Settings
OFF Prevent current from exceeding the OCP setting.
ON-CODE Allow current to exceed OCP setting - See conditions, below .
With 'ISET > OCP+200' OFF ,
The unit will NOT allow the output current to go above the protection value, as
described in the ‘
OCP ’ Setting details.
Except, The time from output current reaching the OCP value and the PS
turning OFF ( Protection Mode ) could be delayed by up to 600ms; rather
than immediately as a more advanced/expensive PS_s would do.
With 'ISET > OCP+200' ON ,
The unit WILL allow the output Current to go to whatever value is selected (I-SET),
regardless of the ‘ OCP ’ value.
However, since the value is above the ‘ OCP ’ value, Protection Mode will still
be activated, after the delay, IF the output current has not fallen back below
the OCP value.
This setup is for load devices with high in-rush current that lasts less than the delay time:
Output current can go over the OCP value for short bursts, to a MAXIMUM of ‘ I-SET ’, and
for less than the response delay, up to 600ms.
The response delay is due to a lack of a hardware-implemented ‘over current’ protection.
This is unavoidable with the RD60xx and cannot be corrected in Firmware.
IF the output current reaches ‘I-SET’ the (Hardware Controlled) fast change to CC mode
would lower the Voltage to maintain the I-Set maximum, until after the response delay.
