Slew Rate
The slew rate is calculated as a function of change in the output voltage and a
given time interval. The maximum slew rate is 1% rated voltage/150us. The slew
rate is saved upon power off and restored at power on. Output ON/OFF and
shutdown are not affected by the programmable slew rate. These functions have a
slew rate of 1%/20ms.
The range of output voltage is 5% - 0.1% of rated voltage.
The range of time interval is 1.5 s - 150 us.
The negative slew rate is limited by the discharge rate of the output capacitors.
During current share, slaves operate with their default slew rate. The master
operates at its programmed slew rate. Hence a programmable slew rate for the
system is achieved. However, this slew rate is limited by the speed of the control
loop. The slaves will return to their programmed slew rate when they exit current
share slave operation.
The slew rate error increases as the slew rate increases.
Selecting
SLEW RATE
from the main menu will give you two choices:
Voltage slew -
adjust the voltage slew rate
Voltage default -
restore the default voltage slew rate
Selecting
VOLTAGE DEFAULT
will return the slew rate to the default value of
1% rated voltage per 150us.
To set the slew rate:
