The fault light is on and the buzzer sounds after the 300W inverter is turned on
Model
BP series pure sine wave inverter 300W 24VDC 220VAC
Description
After power on, the fault light is on, the buzzer sounds, and there is no output voltage.
Analysis of the possibility of the cause
1. Check the internal components, the front and rear MOSfets are normal, check the rectifier bridge, and confirm that the fast recovery diode MUR1660CTA is damaged by breakdown.
2. The cause of the fault in changing the position is most likely to be the fault caused by the overload or short circuit of the output terminal.
Solutions and steps
Replace the faulty diode.
