Hi.
I have some questions for dummy load:
Can I use dummy load at about 1A of current?
Is there dummy load for high current?
When I set the current of driver (V5, microboost) and the current was near 800mA, the serial diodes(1N4001?) of dummy load became very hot and my multimeter showed the fluctuation of the reading.
I don't know the maximum forward current of the diode(1N4001?) but I wonder if this could distort the reading.
Because the power output of my recent A140s (850mA) showed very high over the other member's. I double-checked all the procedure but couldn't find the reason. I don't think all the two of A140s are freak at the same time.
There must be some reason.....I have little knowledge of electronics.....
....but I like to DIY laser.....
Thank you.
