Online UPS input 220VAC high cut - low cut filter PCB troubleshoot.

07-19-2024, 01:59 PM

Hi,
This online UPS is not detecting Mains 220V AC input, by observation I found a SMD Capacitor (C6 which responsible to operate the relay next to R27) is burnt in 220VAC high cut - low cut filtering PCB.
Please share me a suitable capacitor value for this circuit.

Thanks

Input Filter Filling: How to Choose Components?

by cheese007

Recently acquired one of those silly Logisys acrylic power supplies and lucked into getting one of the "better" ones (most of an input filter, bridge rectifier instead of 4 diode treatment, OK-sized heatsinks, etc.) and wanted to fill out what I can on the board + get some decent caps on there (especially the primary side since I highly doubt the ones in there are actually 1000uf). My questions are:

1. How do I know what components to install re: the input filter? It seem to be missing an X cap, a resistor, and a Y cap.
2. Where can I find a good heatsink for the bridge...

820-02020 Super Weird Issue: Keyboard Input Character Map "Wrong"?

by ugamazing

So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:

1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.

2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not...

Texas Instruments bq24745 bq24745RHDR bq24745RHDT Battery Charger IC for Laptop Computers Datasheet

by Document Archive

The bq24745 bq24745RHDR bq24745RHDT is a high-efficiency, synchronous battery charger with an integrated input-current comparator, offering low component count for space-constrained, multi-chemistry battery-charging applications. The input-current, charge-current, and charge-voltage DACs allow very high regulation accuracies that can be easily programmed by the system power-management microcontroller using the SMBus interface. The bq24745 charges two, three, or four series Li+ cells, and is available in a 28-pin, 5-mm x 5 mm QFN package.

The bq24745 features dynamic power management...

Help with boom box modification

by Califauna

Hi, this is more of a project help request than a troubleshooting question. I hope I can post it here.

I have a W-King D8 Bluetooth boom box which I'd like to modify with some external speaker output jacks and some buttons to switch the internal speakers on and off.

From factory the specs of the boom box are:

-Power Input: DC 5V
-Speaker Output Power: 2 x 25W ( confirmed by Youtube channel Hartdegen review as 12.5W RMS per channel)
-Drivers:
-2 x Woofer, 70mm, 10Ω, 70mm,15W
-2 X Tweeter, 8Ω, 30mm,10W x 2
-Frequency...

Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!

by momaka

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

https://www.badcaps.net/filedata/fetch?id=3591771

https://www.badcaps.net/filedata/fetch?id=3591772

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:
