I'm a lighting technician that works in the UK film industry. I was really hoping some one could help me with a SSR switching issue.
I have built a led lightning flasher to simulate storm lightning for a film. This fixture will be attached to a drone and will be switched on and off repeatedly for up to 6 minutes in very short bursts due tho the lack of heat sink. I am using 250 W voltage booster and Constant current driver to power two 100 W LEDs these draws 5 A at 30 V. I have 10 drivers and 19 LEDs in my fixture. I will be using two SSRs to switch two separate circuits via a wireless dc controller system. One circuit will switching a load of 40 A and the second will be switching a load of 30 A.
I'm hoping to use a DC-DC SSR like this.https://docs-emea.rs-online.com/webdocs/10c9/0900766b810c9bee.pdf
I have learnt that I need to use a Schottky diode to protect my SSR. I am not an electrical engineer and I really need help in choosing the correct Schottky diodes for this project and where to put them. I have already killed two SSRs after 10 or so flashes and can't afford to kill any more!
I have attached a basic drawing and a photo of my build to help explain what I'm trying to do.
This is the basic set up for driving two leds.
