FET Switch (U21) is burned below conditions.
DC POWER SUPPLY 12V: CURRENT LIMIT 2A,
WHEN POWER ON,
Q) How can I prevent FET burning?
(Change large size FET?)
(DC POWER SUPPLY Current Limit: 2A to 15A)
(LOAD: 0 to 15A)
(Customer may use DC POWER SUPPLY with CURRENT LIMIT)
Thank you for your help.
I am waiting your answer.
