Assumes slow modulation as when following a base load. Does not consider additional power
required as seen in grid firming applications requiring continuous and fast ramping of power. If this is
expected in the application, please contact Woodward for additional information. Stated current
values are based on minimum DVP input voltage for full dynamic performance.

Information provided for breaker and wire sizing. Current seen when performing a full 100% step
against load. Note: this value varies by actuator type. The values above are applicable only for the
products referenced in this manual. Stated current values are based on minimum DVP input voltage
for full dynamic performance.
