Hi guys and gals!
I have a problem here... And I tought that you could possibly help me!
I have a project where I need to apply a certain voltage (0 to 300VDC) to a resistive load for a given amount of time and then drop the voltage to zero (single shot voltage burst). So in short, I need a relay! But the problem is that I need it to be very fast and high voltage (up to 300VDC). Right now, I use a Crydom DC400D10. It is good for relatively long burst (200us and up) but I cant get lower that that due to principally "toff" delay and rising and falling time.
You can see here (on top) in that shot (1200us corrected on the output voltage, the signal is shorter to take into account the ton and toff) that the toff delay is pretty long.
I can live with "ton" delay as what I really measure is the total energy but the rising and falling times and "toff" are really killing it.
What I really would like to have is something in the order of 10us. I dont know if you know any SSR that is capable of that?
Thanks for your advices!
