Programmable Maximum Output Voltage (VOUT_MAX)
The output Voltage can be programmed using the “Direct data Format”.
Please refer to Table 5-1 for
the Coefficients to be used for calculating the Voltage Programming.

Example:
Power Supply RFE1600-24;
To program the maximum programmable output voltage to 29V.
Send ((-15360))/10 = 938 (DEC).
5.3.6
Programming Output Current Limit
The accuracy of the Current Limit Programming
is +/-8%.
It is possible to program the OCP with the PMBUS. The OCP can be programmed between 50%~110% of nominal load
current. Please refer to Section 1.1 for the current limits at respective levels
The output Current can be programmed using “Direct data Format”.
Please refer to Table 5-1 for the Coefficients to be used for calculating the Current Programming.
During Current programming, Vout Max must be programmed to maximum limit.

IMPORTANT:
When using the PMBUS to program the current limit, the output voltage is set to the rated value as a default.
To set the output voltage to different level, Please refer to Section 3.2.5; 3.2.6.
Example:
Power Supply RFE1600-48;
To program the Current Limit to 100%, send ((-5830))/10 = 877 (DEC);
Read the actual Current (Ex: 32.5A) / Accuracy is (32.5-33)/40(*1)x100 = -1.25%.
