Anonymous users2024-02-05It's about the same as the amount of 3-level tubes, I use the M47 meter X1K file, don't care about the side to you, the middle foot is connected to the black watch pen, and the forward resistance of the two feet is 5K. The reverse resistance is not the same, one does not move, and the other is around 200k. That's good.
Forward and negative are too big and too small, both are bad.

Anonymous users2024-02-03ACT30BHT is not a transistor, it is a switching power supply control integrated circuit, with 3 pins, one connected to 5V, (more connected to the emitter of the power supply power tube), one to ground, and one connected to the control output (more connected to the photocoupler).

Anonymous users2024-01-31ACT30BHT is a TO-92 package of AC DC switching power supply ** (1 30W) produced by ACT company, mainly used in induction cooker, there seems to be no equivalent performance can be replaced, but can be changed with universal power supply.

Anonymous users2024-01-29ACT30 is a common low-power switching power supply chip on induction cooktops. There is no replacement, but it is very easy to buy, 2-3 yuan a, it is best to repair the original circuit as well.

Anonymous users2024-01-28It can not be replaced by the power module on the TV, because the switching transformer has a small inductance, it is recommended to find an ACT30 power supply IC is relatively simple and feasible If necessary, please welcome Q I 38410478Do your job responsibly.

Anonymous users2024-01-27I don't have anything for sale here. I would like to replace it with a three-wire power module used on a regular TV. But I don't really understand the circuit of an induction cooker.
13002 should be a ** switch tube. Connect the red line of the module to its C level. The black wire is connected at a negative level of three hundred volts.
Is that okay. Adjust the voltage again. Is that okay.

Anonymous users2024-01-26Check the step-down resistor, 13003, Z2, Z4, resistance and ACT30BH in front of the switching transformer.
ACT30BH is a power management module, about 1 yuan or so.

Anonymous users2024-01-22Only 220V rectifier DC works, so there is 300V, and the other electronic circuits after it have not worked, there is a fault, and then check.
-
Anonymous users2024-01-21This shows that the switching power supply is not working, 300V is only the power supply voltage after rectifier filtering, this should check the switching power supply chip itself and the peripheral circuit and protection circuit

Anonymous users2024-01-20What do you instruct? Anyway, I didn't understand it. Do you want to rectify the circuit or do the problem?

When you are struggling to pursue a girl, but there is no result, you should stop and think about what kind of boy the girl you like likes, and then you try to get closer to this direction, to change, and finally become the person she likes.
But many things still have to be chosen according to the individual, because most of the time, everyone chooses differently, and what is expected is different, and many times he is different, because the standard of living is different. Nowadays, I prefer to get cash, some people prefer gifts, and if you have a letter, you will prefer to eat something delicious, and this is chosen according to each person's differences.
