Protecting Absorption Capacitors

Notes

In power supplies where thyristors are used as switches, they are connected in series with resistors to form an RC absorption protection circuit. This circuit prevents voltage spikes during thyristor turn-off, thereby protecting the thyristors.

。Altitude Environment: <2000m
。Temperature Range: -25 to +40°C
。Humidity Level: <85%
。Protection Rating: IP00 for indoor installation
