Hi, I am an IT engineer and electronics is not really my strong point.
I am making a studio ring flash for the wife's studio as new ones just cost way way to much.
I have ripped apart 6 Olympus T20 flash units and salvaged the triggers, Photo-Flash capacitors and Xenon tubes from them.
I want all six to fire with the one trigger and one charging circuit.
I have drawn up the below circuit made from various information I have found on this site but like I said before my electronics understanding is limited so was hoping someone that does know something could look over the circuit and tell me if there is anything odvious wrong with it before I build it.
Here are the specs of the parts I have
-> Capacitors I have for C1,C2,C3,C4,C5,C6 are all the same and have wrote on them Photo-Flash 330v 450uF Auto-Cap FLX
-> The 6 triggers have the following specs
Trigger Coil (Trigger Transformer) for Xenon Tubes Secondary Voltage (Max unloaded) 11 kV
Primary VOltage (Max unloaded) 300 V
Trigger Energy (Max) 10 mWs
Trigger Power (Max) 0.5 W
Transformer Ratio 1:36
Primary Inductance 20 uH
Trigger Capacitor 0.047 - 0.22 uF
-> For R1 the power resistor I have purchased 1 x 47R 100W Aluminium clad wirewound resistor, Resistance tolerance 5%
-> The flash tubes are all 28ws CB254200Xe Lamps
-> Rectifier Diodes are all 1N4004 1AMP 400V (not to sure about these, are the amps enough?)
-> SCR 400V 0.4A Igt 30mA http://www.datasheetcatalog.org/datasheet/MitsubishiElectricCorporation/mXvrrvu.pdf
-> MOC3020M Integrated Circuit x 1 K3020 http://pdf1.alldatasheet.com/datasheet-pdf/view/176764/FAIRCHILD/MOC3020M/+0WW775UwYhRDpKxHeyUKwvDC/+/datasheet.pdf
Can someone please look at this circuit for me and the components I have and tell me if it will work.
Thank you very much in advance.
