Note: Please refer to the model Spec. sheet for bandwidths used to report recovery times. For products manufactured in the United
Kingdom it may be assumed that recovery times are based on ISO8528-5 G2 class bandwidths. Voltage and frequency recovery times
are estimates. Typically, allow five to ten seconds between application of load steps when designing your system.
*Caution: The starting PF for this step exceeds 0.8 lagging. The actual transient performance of the generator for these steps may vary
compared to the results predicted by GenSize.Contact your Cummins Distributor for Guidance.
**Please note that in some cases the voltage and frequency recovery time estimates are not shown in list. This is a result of "dummy"
data points temporarily being used to fill data gaps in the GenSize database. Please disregard these blank results.
*Note: Contact your Cummins Power Generation Distributor for Recovery Data
