CCPA Board Level TestCCPA Board Level Testquantity:4 FM, 2 FS, 4 QM

before coating:- check of output voltage puls shape- load test- adjustment of HW current limit (max power 150W/CC @126V)- calibration of voltage*current readout- relais check (launch lock)- full functional test

10 x CCPA

• all failures could be repaired and defective parts were replaced
