https://www.edaboard.com/members/529643/ and https://www.edaboard.com/members/569777/ is there a way to remove the epoxy without damaging the components?.
Hello Enthusiasts!
I would like to ask if anyone of you knows what is this glue added in some power supplies or generators. Please give me the name. Thanks a lot. See attached photo.
Best regards,

Hello Enthusiasts!
I have this capacitor, please see image, but I want to verify if this is really 10uF. But the voltage rating is confusing... this is used as RC (in parallel) connection from MOSFET output. MOSFET is rated at 550V.
106K 100A - picture marking
Please help me verify.
Thanks...
Hello All Enthusiasts!
Could anyone please tell me what kind of part is this in the picture? I tried searching the net but I could not get an accurate result.
Thanks/deJong
is this what you are talking about?
I checked and traced back the output and found this relays directly connected to its output. I also measured the one you mentioned, Out and Sense high reads open while Out and Sense low reads around 34Mohms. Please check this block diagram. I don't have the...
Hello Electronic Enthusiasts!
My old DC source giving me troubles. Used to be very accurate in producing output voltages for Sense (Hi and Low) and Out (Hi and Low).
Here are the pictures. The source is programmable, and outputs and are exact anymore. The lower voltage you want, the higher you...
I don't have the complete schematic Orson. I don't have also the data sheet for the transformer. 28003309 Mech-tronics label is all I have. Any ideas what is this transformer.
Series coupling caps are for steady state volt-second balance and prevent transformer saturation.
it's single ended input, totem pole output

I did not check my transformer with the scope. Im not sure if it's a 1:1 tx. it is small 28003309 from Mech-tronics
here's the updated IGBT circuitry for the IGBT.
I have measure my gate to emitter using o'scope and the frequency measured is 50kHz for both. PWM frequency is around 101kHz also. see pics below
compared to the theoretical calculation:
PWM UC3524, F=1.18/RtCt
Rt=866 Ohms
Ct=0.01uF...
