Internal Fuse; Startup Times - Iridium EDGE User Manual

3.1.5

Internal Fuse

The Iridium Edge contains an internal, non-serviceable internal surface mount fuse to limit the current in
the event of an internal short.
3.1.6

Startup Times

The Iridium Edge uses an internal super capacitor to limit the current which in turn minimizes the voltage
drops on the power and ground return. Before the Iridium Edge can reliably start operation, its internal
super capacitor must be at least partially charged. The internal super capacitor is charged when a valid
voltage is present and when the Iridium Edge is not powered down with the On/Off control line.
The table below outlines the specifications for the startup times for the Iridium Edge to startup its internal
SBD modem.
