@@我走我留 thank you

@@frogproduction8388 After testing, after changing the protection voltage, the highest can be 69V. If you need 73V, you need to readjust the output transformer. The transformer has two coils, and change the double coils in parallel to series (the coil needs to be reduced by 2 turns and then connected in series).

@@我走我留 感謝🙏回覆

@@trongminh2804 Yes, that's right. Disconnect the PCB next to the CPU (Note: 8 for versions above 00)

Because the circuit has been changed, the CPU thinks it is a malfunction. In fact, this does not affect the use. Don't worry about whether it is a red light, as long as your output voltage can be adjusted to 0-60V (actually it can be 0-70V)

可以啊，我的也还要重新改一下配置

Tôi cũng quan tâm vấn đề này. Mong được giải đáp

@@HaLe-hd8ce Được nhé bạn, đã test thử dùng module DAC để điều khiển ok nhé

@@tientun mình dùng Riden 6012 cũng Ok thôi phải không

@@HaLe-hd8ce bộ đó có sẵn chỉnh nguồn rồi, không cần mod thêm mà đấu thẳng là được

No, only ESR4856A can

我买的是24V的，直流电。只要二根线，正接正转（升），反接就反转（降）

@@我走我留 也就是說~再買一個24V變壓器~從(台灣)家用110V或 (大陸)家用220V接到變壓器上就行了嗎?

@@cool6084 对，AC110V变DC24V的就行

@@我走我留 感謝你的回覆^^

yes

First confirm your version. If it is the S2 version, you need to cut off the PIN 33 of the CPU (it is difficult to cut the PCB lines); if it is 00 or above, you need to cut off the PIN 8 (it is easy to cut the PCB lines). After adding a 10K potentiometer, the actual voltage can be between 0-70V.

no

can u get it. like this one@@我走我留

Very simple, voltage part two: remove a 10K resistor and use a 20K potentiometer (42V-60V). Current part: Cut off the current detection line and connect a 1.5K potentiometer (0-38A) in series.

Thank you sir ji

When these two lines are connected, it is turned on, and when it is disconnected, it is turned off (on and off).

@@我走我留 there is an esr48/40a power supply, when jumpers 2 and 3 or 2 and 4 are closed, the power supply flashes the rfa/ff indicator (at the same time, when the unit starts, 41.5 volts appears, then the rfa/ff indicator starts flashing and it gradually drops and drops to zero) please help!!!

可以更换新的电容，用100V耐压的。我的方法是把6个电容，每2个电容串联，变成3个126V电容。

厂家说明书上有安装图标示尺寸的

这里也能遇到你啊

U27 pin4 and U24 pin4 are the same SGND, you can also connect to other SGND on the circuit board. You don't need to consider the capacitor (C) connected to the right, because this wire is the original line. I drew two capacitors (C) on it, but the U27 and U24 are arranged in a schematic diagram.

U27 4=SGND，U24 4=SGND。U27→C→U24→C→JB2. Both are on the position arrangement diagram on the circuit board (left→right)

@@我走我留 , thank you so much for your fast answer and clear explanation, good job and have a nice day

@@我走我留 , good morning, I have an additional question on your video at minute 3:11, why did you remove DA44, DA45, DA46 and DA47 and CA75? those parts is necessary to remove due to change from half-wave rectification to full wave rectification? Thank you so much in advance.

@@saifulbadri1143 If you need 0-60V, you don't need to change this part of the circuit. If you need 0-120V, you need to change this part of the circuit. There are two ways to change 60V (50A) to 120V (25A). The first method is to change the two-way parallel mode rectified output voltage to series. The second method: the two-way parallel method is rectified to a full-bridge rectification (I use the second method). ​ ​如果需要0-60V，则无需更改电路的这一部分。 如果需要0-120V，则需要更改电路的这一部分。 有两种方法可以将60V（50A）更改为120V（25A）。 第一种方法是将输出变压器的二路半桥整流输出电压，由并联改成串联（半桥整流方式不变，只是改成串联）。 第二种方法：将输出变压器的二路半桥整流输出电压改成全桥整流（我使用第二种方法）。
