Chapter2 NetS9 power and battery
NetS9 provides a stable external power while providing a built-in battery as UPS functions.
When plug into charger, the internal battery has automatic charging function; in the case of
external power failure, it can safely switch to the internal battery automatically and ensure
NetS9 stable operation for about 15 hours; similarly, when the external power supply is
restored, built-in battery-powered mode can automatically safely switch to external power
supply, then internal battery enter into the power storage state.
2.1 Ext power
The right to use an external power supply of NetS9 precedence over the built-in battery. Only
when the receiver is not connected to an external power supply or external power failure, the
internal battery will work.
For a receiver to work properly, the external power supply must provide 9V DC to 28V DC,
and the power must be greater than 5W. When external power is disconnected and the built-in
battery is exhausted, NetS9 will automatically shut down; when the power is restored, the
receiver automatically starts and its configuration parameters will be restored to pre-shutdown
state, and begin normal operation.
Warning: Do not place the external power adapter, its subsidiary plug, and cables to
outdoors or in damp places. Do not use an external power to supply power when
receiver works in a humid environment.
Warning: External power supply input voltage cannot exceed 28V DC, otherwise the
receiver will have a fatal injuries.
