Input Power
The EGCP-2 accepts any input power source that supplies a voltage within the 9-
32 Vdc voltage range. It is expected that the installation of this equipment will
include overcurrent protection between the power source and the EGCP-2. This
overcurrent protection may be accomplished by series connection of properly
rated fuses or circuit breakers (see the Input Power Ratings below for proper
sizing).
Input Power Ratings
Nominal Voltage Range: 10–29 Vdc
Maximum Voltage Range: 9–32 Vdc
Maximum Input Power: 20 W
Typical Input Power: 13 W @24 Vdc
Input Fuse Rating: 5 A (time delay with melting I²t  100A²sec)
Wire Size: Up to 12 AWG
Holdup Time: 5 milliseconds @ 24 Vdc
Significant inrush currents are possible when current is applied to the EGCP-2
control. The magnitude of the inrush current depends on the power source
impedance, so Woodward cannot specify the maximum inrush current. Time-
delay fuses or circuit breakers must be used to avoid nuisance trips.
