the CLOSED position.
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
Part Number: 8406-115 and 116
Supply Voltage Rating
Nominal Voltage Range: 10–29 Vdc
Maximum Voltage Range: 9–32 Vdc
Maximum Power: 20 W
Typical Power: 13 W
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.
