It smooths the pulsating DC output from a rectifier by storing charge during peaks and releasing it during troughs, reducing voltage ripple and suppressing high-frequency noise.
Typical total bank capacitance ranges from 100 to 1000 µF, and rated voltage from 400 to 690 V AC, but these must be confirmed for the specific model.
IEC 60831-1 for capacitor parameters and IEC 60529 for enclosure protection. These are references, not proof of compliance.
Increased ripple voltage, overheating, bulging or leakage from capacitors, or failure of downstream equipment may indicate degraded performance. Regular inspection and testing are recommended.
