ماشاءاللہ سر ایک اور معلوماتی ویڈیو دیکھ کر خوشی ہوئی اللہ اپ کے علم اضافہ فرمائے

[@test0957]

This man is an amazing master in his job. With his help, through online consultation, we repaired two 5KV UPS controller board. . Only after describing the problem, he immediately showed us the damaged part... Now both of UPS working like a new. Lots of thanks and recommendations from me. I want everyone who has had problems with UPS devices, to know about him. He has an expert knowledge. That's why I write this comment on all his videos. I spent 4 nights without sleep looking for the problem. 👍 👍👍

Sir i am checking one surt3kva when i soft start battery relay 702 not closing,then i found q707 getting fault when start.i changed control card at that time q707 not getting fault.What may be the fault with control card having connector black flat type not the ethernet type

[@ganeshm1735]

Sir I have another doubt can I use 10kva control to check 3kva to verify the problem with control card

[@AKElectroTech]

@@ganeshm1735 there will be multiple faults that controller stop PSDR power.

sir ji . i want to down load SW from ST72324 MCU which is used in APC BI850sine Inverter ..can u pls suggest how to do that . I have CH341A in my hand

[@varishali9111]

SurtD5000 uxi controler card working ok but no display..... Only display not working... No LED glow.... Only on off button working.. Where we serch fault in controller card... Please reply

[@AKElectroTech]

@varishali9111 ON/OFF switches on display panel are separate and rest LEDs are separately operated on display panel. First of all check RJ45 cable between controller and display panel. Check connection between IC 3 pin 2 which is used on display panel. This is +5v DC used on display panel. If +5v is coming then check RN24. I hope you will find solution

replace fan or drive where connector is connected. IC36 and Q36 are used for fan drive and fan error

Hello friend No at this time.

[@PakGuides]

Greeting sir, I have a surtd 3000xli showing the error 00010 I replaced the control board with a new one, and the error is fixed. Can you help me sir where is the fault in faulty control board. Thanks in advance

[@AKElectroTech]

@PakGuides This fault 00010 is related with backfired relays. Backfeed means that AC input relays are not operating. There may be so many issues in control card. 1. Backfeed relays are operated by IC18 (ULN2003). Check wiring pin 13 of this ic to backfeed relays. 2. It is possible that controller stop back feed relays due to not sensing AC input. You can check D23, IC35 and IC27 and related components. This portion is used for AC sensing. 3. It is possible that ADC is not sensing AC references at pin_120 and pin_121.

olá tenho uma placa de controle do SURT 6KVA com falha PFC como eu faço pra resolver essa falha

[@AKElectroTech]

Hello Which PFC side is not working. Pl follow these steps Install batteries in ups and apply input voltage to ups. UPS power supply will activated and check DC positive bus on d716 and DC negative bus on d715. Now which bus side is not working on supplying input power to ups.

[@mailsonfreitas3967]

a placa de controle assim que colocar a tensão de entrada ele já dispara o disjuntor da bancada. Não dar tempo de verificar as tensão positiva e tensão negativa no diodo.@@AKElectroTech

[@AKElectroTech]

​@@mailsonfreitas3967 You mean that input circuit breaker tripped when applying input voltage to ups. If this condition appears then check input circuit of PSDR board. Otherwise follow these steps: Connect batteries to ups and connect dmm negative lead to battery black and positive lead on d716. Now switch 'ON' ups on battery and check DC voltage on this diode. Same for d715 diode and check DC voltage. Also check that ups is normal functioning on battery or going to pfc fault state. Then apply input voltage and repeat same procedure. I hope you will find any solution

[@mailsonfreitas3967]

olá amigo!! tenho surt6000kva xli ta com falha DC BUS OVERVOLTAGE eu identifiquei que o problema tá na placa de controle. a tensão no diodo 716 tem 200 volts no diodo no 715 tem 67volts. você pode me ajudar.

[@AKElectroTech]

Dear friend How do you identify control board? Connect batteries and apply input voltage. Now check D716 and D715 for +ve and -ve bus.

[@mailsonfreitas3967]

hi bro, where is connection of cathode of diode 24(D24) that is below 74htc245(ic 19)? this diode of control board was burnt but cathode of that has no connection with everywhere?

[@AKElectroTech]

Brother D23 is used after input transformer on PSDR board and convert AC sensing in to DC voltage and connect it to D24. D24 received 24VDC from D23 and 24V_SW from LV power supply from PSDR board. D24 cathode connected with R182 parrallel with R250. Both R182 and R250 are 100 Ohm.
