External A/C Power

The Alternating Current (A/C) connection to the GSA Unit accepts input voltages from 90 to 250 VAC at 50 to 60 Hz, as stated on the External A/C Power panel. Depending on the components in use, the state of the various batteries in the system, and the current operating conditions, the system will draw up to one ampere from the source. The system has circuitry to ensure overloads do not cause damage to the GSA Unit or to the installed components. The system also contains protection against heat by monitoring the temperature inside the case to ensure it does not exceed 170 degrees Fahrenheit.

NOTE: When the case exceeds 170 degrees Fahrenheit, the case will shut itself down. After the case has cooled down, the case will be able to be turned back on. This downtime depends on how hot the case was when it finally turned itself off.

A/C electrical power is supplied to the GSA Unit through a standard, three-wire power plug connected at the back panel of the case (as shown in Figure 3). Connect the other end of the power cord to a three-prong power source. Using appropriate adapters, the GSA Unit may be connected to a wide variety of sources. Since it will accept a wide variation in input voltages and frequency, as described above, the GSA Unit can be safely connected to standard A/C power sources throughout most of the world. Nonetheless, precautions must be taken to ensure the power connections are correct. In particular, the GSA Unit is not certified for direct connection to US military aircraft since power is usually generated at 400 Hz unless indicated on Input Power Panel.

The GSA Unit contains circuitry that will automatically reset after an overload, but if the system fails and does not come back up after approximately 10 minutes, the unit must be considered in a non-recoverable condition and should be returned to the factory for repair.
