A simple AC-DC power supply circuit outputs about 6.1 volts DC without a filter capacitor connected, and about 9.3 volts DC with a filter capacitor connected: Explain why this is. How can the addition of nothing but a capacitor have such a great effect on the amount of DC voltage output by the circuit?
The battery symbol on the screen reports external power - as AC or the voltage (11.7V with a fresh cell). Other than a faulty Smallrig plate, my suspicion would fall on the batteries but, since you have more than one, you''ll have covered that. Besides, the camera shouldn''t power off if it still has power in its internal cell.
Solved: AC adapter not detected, battery does not charge, …
It could be something as simple as the DC power conector on the notebook is damaged or a component of the power/charge subsystem has failed. (Mosfet/Capacitor/resistor} Power/charge LED lit means that the power adapter and charging subsystem is OK. A new battery or power adapter will not resolve that.
If the set value is exceeded, the inverter reports inverter failure of DC overweight inverter failure. Reason: A sudden change in DC input power may cause this inverter failure. Solution: You can turn off the AC/DC switch, restart the inverter and try again. Check whether there are high-power electrical equipment near the photovoltaic …
