Reverse Time As A Function of Voltage Limit
Note: Not all Pinnacle Plus+ units are shipped with reverse time as a function of
voltage limit. This is a special feature that your power supply must be
configured for at the factory.
Some processes require that the Pinnacle Plus+ power supply allow a longer duration
when reversing the voltage. By utilizing the V-Limit function of your power supply,
you may be able to increase the reverse time to a maximum of 10 µs (when voltage is
limited to 325 V). When the unit is set for 650 V (or higher in Hi-Z models), the
maximum reverse time is 5 µs. As you decrease process voltage using the V-Limit
function, the reverse time increases linearly until it reaches the maximum allowable
value of 10 µs.
Note: The maximum reverse time duty cycle is still 45%.
Figure 3-2 on page 3-11 is a graph of pulse reversal times as a function of the user
voltage limit. Table 3-5 on page 3-11 provides a detailed list of reverse times and the
corresponding user voltage limit.
