Series CW3 specified for charging point.
Designed for power supply,low voltage inverter
High temperature,105a 3000hours
Temperature range:(16V~100V)-40~+105 (160V~450V)-25~+105
Voltage range:16~500
Capacitance range:68~47000 @20a ,120Hz
Capacitance tolerance:A 20%
Insulating Voltage:Apply AC 2000V between all terminals and snap ring with insulating sleeve for 1 minute and no abnormality appears.
Durability:Apply rated ripple current on capacitor with voltage not more than rated voltage under105a environment and apply rated voltage for 3000hours,then recover to 20a environment and the test results should satisfy the requirements as below.
Capacitance change rate (a ci a initial valueA 20%
DF(tgI'i a 200%of initial specification value
Leakage currenta initial specification value
High-temperature zero load characteristics:Capacitor kept in 105a environment for 1000hours,then tested in 20a environment and the test result should satisfy the requirements as below.
Capacitor change rate (a Ci a initial valueA 15%
DFi tgI'i a 150%of initial specification value
Leakage currenta initial specification value
(Voltage pretreatment should be done before test:apply rated voltage on both ends of capacitor through a resister of about 1000IC for 1Hrs,then discharge electricity through 1IC/V resister after pretreatment.
