There are many ways to judge the aluminum electrolytic capacitor used by UPS. The quality of the aluminum electrolytic capacitor used by UPS depends on the manufacturer.

 

If it's not specially designated by the customer, it's a long way to judge its quality. Of course, it's a long way to go for engineers and technicians to test through samples sent by multiple manufacturers, and compare multiple performances (such as capacity tolerance, loss tangent of capacitor, leakage current, ESR, heating of capacitor, stability of ups after operation, long-term sexual load After the test, the capacitor should be the same, and the one with better comprehensive performance will win.

 

Of course, after the capacitor is sent to the laboratory of the technology department, it will conduct preliminary quality performance test, such as quality detection, boosting speed, capacity, loss tangent, leakage current, ESR, core temperature, life, etc.

 

Qingquan electronic aluminum electrolytic capacitor manufacturers recommend that UPS customers use capsun long-life capacitors in the selection
