Hello, It looks like this schematic: Jan 15, 62 0. Hello, The drawn coil is the loadin your case the lamp. There are no part numbers anywhere on the pot.
So, it’s either I replace the old pot on the board or I just design another board in place of the one already there. Need help to identify lamp in board for LED backlight – sewing machine repair Posted by cdc in forum: Yes, my password is: However I notice an extra resistor in the current circuit for the lamp, is that put in parallel to decrease the voltage drop?
Is this diagram from the circuit you pulled out of the lamp? There are 18 btac suppliers, mainly located in Asia. September – Ed: It also looks like a voltage regulator is on there? No circuit design but a simple explanation of a dimmer switch Without any markings it is impossible to tell what resistance or power rating the pot is.
We are not responsible for any accidents, delays or 400x issues caused by the forwarder. You can ensure product safety by selecting from certified suppliers, including 1 with ISO certification. Non repetitive surge peak off-state voltage. I know the triac but the caps I’m not sure. Does anyone recognize what type of pot that is?

I assume there is a 12v ac signal coming which I input to the pot, but then it looks like there are 2 caps and a resistor in parallel with the pot? As far as component selection, I would try to identify the components on 400 current board and start there.
The ground wire is not interrupted at all throughout the lamp. I myself just went to the hardware store and bought another dimmer, so my experience ended with the website. It used to be available at Radio Shack.
The potmeter will probably be in the range of KOhm. May 6, 8. All products will be tested by 3 times before the shipment. Now I just need to find a replacement. May 4, 7. On-state characteristics maximum values. May 4, 1.
Warranty and Return 1. It is sometimes referred to as Solder Wick or desoldering braid.
You can get 4400c copper braid that will wick up the solder after it is heated. May 4, 3. Surge peak on-state current versus number of cycles. However, STMicroelectronics assumes no responsibility for the consequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use.
Also, I think I’m going to go off the circuit they have on this site http: May 4, 2. Also, is that long metal piece coming off the triac for heat dispersion? Is there anything written on the back side of it?
Sep 25, 1, Apr 5, 18, 3, Analysis of Forward Conducting Diodes In this article, we will learn how to analyze circuits that utilize forward conducting diodes. RMS on-state current versus case temperature full cycle. I actually was just able to remove it.
May 6, How to repair a flickering led lamp Posted by Nicholask in forum: Critical rate of rise of on-state current I.
