I have purchased an LED Driver for fountain musical lights application but it get damaged within one or two days.I am unable to find exact problem in the system.I am switching LEDs with Solid State Relays.So my question is there problem with LED driver or with the Solid State relay switching which causes problem?
LED driver is of
1. 230V RMS ac input
2. 4W ,0.7A current output
3.3 LEDs in series
most probably the LED driver works as current source.
when the LED is disconnected (solid state relay open) then the voltage rises to it´s maximum.
When now then solidstate relay switches on there may be high current until the voltage is down to its normal value.
So either the high voltage causes the problem, or the high current peak.
