Power Supply
5G routers are usually used in complex external environments. To adapt to the complex
application environment and improve the stability of the system, the router adopts
advanced power supply technology. Users can use the standard 12VDC/1.5A power
adapter to power the 5G router, or directly use the DC 9~36V power supply to power the
router. When the user uses an external power supply to power the router, the stability of
the power supply must be ensured (the ripple is less than 300mV, and the instantaneous
voltage does not exceed 36V), and the power supply must be greater than 8W.
