1.6 Power supply requirement
Devices are often used in complex environments, in order to adapt to the complex application environment and
improve the stability of the system, the equipment uses advanced power technology. Users can use BIVOCOM
12VDC/1.5A power adapter to supply power to the device, or directly supply power to the device with DC 5-35V
power supply. When the user supplies power to the device with an external power supply, the stability of the
power supply must be ensured (the ripple is less than 300mV, and the instantaneous voltage does not exceed
35V), and the power supply is guaranteed to be more than 4W (excluding the power consumption of the external
sensor).
Using Bivocom standard 12VDC/1.5A power adapter is highly recommended.
