- （Red light is on, no need to pay attention）Constant Current-Constant Voltage Charge。版本REV:S2比较难改，切断S2版本的33脚的位置很难操作，导致有少数人切断后无法开机，主要原因是没有完全切断和焊接电位器中心电线时有焊锡过大引发故障，请尽量使用其它版本。非S2版本的机型CPU是切断8脚，切断很容易，切断后焊接电线也非常容易。建议新手不要使用S2机型改制。（红灯亮无需理会）
台达4850， DELTA ESR48/56 4840也应该一样结构。

Thanks, Just bought a ESR-48/60a. I haven't hooked it up yet, but if I do not get power It may be the jumper (between 2 and 4) in the middle. This is the first place I've found where it described the jumper!
hello.did you buy an ESR-48/60a? My video is the ESR-4856AC, I haven't tested if the ESR-4860A will work.
Yes I bought one, I haven't had time to test it yet, but I appreciate you posting about the jumpers, with or without it should work!
Nice video. Thanks you sr.
Please tutorial adjustable for Huawei r4850/75
Great information! thank you, this is suitable for ESR 48/40 AA REV:07? or these are different power supplies..
Thank you very much for the video but I need a simpler solution. Just to drop some voltage. I have model ESR48/56B A Rev.09. Can you help with a simpler method for this?
Great 👍
0-60V is very simple, the third OCEP is disconnected, the CPU 33pin of the S2 version is disconnected (8pin of other versions are disconnected) and 10K and 100K are connected. If it is DIY 0-120V and voltmeter and ammeter, it takes more time.
good job
Nice..
@@taryoto9751 If you don't install a voltmeter and ammeter, DIY 0-60V is very simple! Just cut off the CPU pins and solder the wires to the potentiometer. 0-120V DIY is very time-consuming.
I am having ESR48/56A B REV 01..Is it same as this video? Need only 0-63v.
Do you know how to modify EPW30?
I just have converted my esr-48/56a c (rev. S2 model) rectifier by following your guide, so far , the function is working well with no problem , but just have the led status ( Red < RFA/FF> and yellow ) not so clear, can you please tell my what the meaning of the RFA, FF and CL for me as an reference ?Thanks !
Note: Capacitor C is the chip capacitor next to UB27 and UB24. The picture is to tell you the correct pin position of UB27 and UB24. Do not change any of these two chip capacitors.
In the case of adjusting voltage and current, can I use a voltage regulation module to adjust it through another device? I want to control it precisely through DAC modules. Is it possible?
Is it ok for ESR 48/56B F c Rev: 12

Hi I need more explanation for this. to which pins and what kind of potentiometer. Could you please be more descriptive.
Jika saya hanya butuh 27v saya harus memasang potensio yang mana??

@@user-cw5gz4fs3r Thank you for this information. I was worried because I didn't understand what the symbol C on the diagram meant, and I even considered cutting it, lol

How much for someone to sell me one that can do 120v 25a to the USA
Hello master, Can you please tell the instruction for delta 4000b?

I only have the circuit diagram for the DELTA 4856.
Maestro, tengo la referencia ESR 48/40A y mi pregunta seria si las resisencias que mencona en el video hay que cambiarlas y si los potenciometros se montantan sin las resistencias que menciona, le agradeceria su ayuda
I'd love to help you, but I didn't understand your question clearly due to the google translate I used, but the translation was wrong. Please re-describe the problem in detail. (Did you mean the potentiometer can't be found?)
@@user-cw5gz4fs3r las resistencias que usted menciona se tienen que cambiar?
Hola, si necesita 0-60V, no es necesario reemplazar la resistencia. Si necesita 0-120 V, deberá reemplazar varias resistencias.
@@user-cw5gz4fs3r Gracias maestro, saludos desde Colombia
Hello boss, I want to ask a question and hope to get an answer. I just want to be able to adjust the voltage from 0 to 60V. What I need to do is add a 10k resistor and remove pin 33 of the MCU, right? And the source will run at its full capacity, right?
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.
Buen Dia,
quiero encender un modelo ESR-48/56A F REV:04, lo enciendo pero no me da voltaje de salida -56 v no se si hay que puntar otros pines?
Please refer to my video picture, short circuit pin2 and pin4 to start the power.
so ligar pino 2 e 3
@@rogerkloss me funciono perfectro . gracias
voltage regulator, I will have to disconnect pin 8 from the cpu to the board, and solder the potentiometer to pin 8 on cpu, right?, thank you
@@trongminh2804 Yes, that's right. Disconnect the PCB next to the CPU (Note: 8 for versions above 00)
I have ESR48/56B A Rev.09 model. Can I do what you do for this power supply?
No, only ESR4856A can
Hello Have nice day Please help me My power is Delta 48V/40A Rev 01, Already cut protech voltage dow 8 pin cutting and 35,36 pin fix to Gnd But power on... red led error...?
What erro..?
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)
Thank you @我走我留 it is very helpful. but I have some questions. Is pin no. 4 of the UB27 and UB24 must be disconnected from the SGND on the PCB or left connected and the pin of the VR 100K connected to pin no. 4 which remains connected to SGND? the second question is pin no. 5 of the UB27 were also disconnected from the PCB and connected to a 100K VR? thank you so much in advance
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)
@@user-cw5gz4fs3r , thank you so much for your fast answer and clear explanation, good job and have a nice day
@@user-cw5gz4fs3r , 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）。
Merhaba, Delta ESR-48/56C modelinde videodaki gibi 2 ve 4 nolu pini kısadevre ediyorum fakat çalışmıyor.Yardımcı olursanız memnun olurum.Teşekkürler
Merhaba bu cihazlardan elimde 10 adet var ihtiyaçınız olurmu?
На выходе конденсаторы на 63 вольта
Как работает регулировка до 75 вольт ?
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。
It is not clear how to install the ammeter
Hello, if you want to make this special ammeter, you need to change a 0-100V voltmeter to a 0-6.00V voltmeter, because when the current signal output by UB14 is 6V, the actual current is 60A, and when the voltage is 3V , the actual current is 30A, when the voltage is 5V, the current is 50A, when the voltage is 0.1V, the current is 0.10A... Got it? You need to turn a 0-6.00V voltmeter into a 0-60.0A ammeter.
Can it be applied to ESR 48/40 A A-S REV:07 Sir ?
Ocep disconnection - just to raise a leg from circuit board?
Yes, you can cut a leg with a sloppper, or remove the entire OCEP.
