I am trying to repair a SF-PW yamabishi make CNC sprintle control power supply.
Now the smps on but,switching transistor C3150 getting too hot.The older transistor was C3148.
I put C3150 instead of C3148. the datasheets are almost same .
anyone have experience about this power supply please...
Attached here with a program file 8051 based.
According to this program, all LED s are direct on when the power switched on.
and off when the button press one by one
I need to change the program, all LEDs are OFF when the power switched on.
and ON when the button press one by one.
A Lithium iron Phosphate battery voltage is 3.2v and capacity is 5000mAh.
what is the charging current if I make a charger for single cell ?
Data sheet said that 1C rating.
if 1C =5 amp for one hour that means a 5amp charger enough ?
I need a charger circuit for 12x 1.2volt,2100Mah NI-MH Batteries .(14.4V)
here what will the out put voltage and current for charging this 12 batteries ?
which switching transformer for suitable this application ?
Can you help?
This is a simple LED on off with a push button program. can you help me to add ; when push the button more than twenty (20) seconds
The LED should be OFF.

I have attached an image of a pepper type reflector for sensing applications.
Can you tell which type of material is this and which type of sensor sutable for
This reflector . If possible make a schematic also.
I am try to repair this SMPS Siemens SITOP 20 .
When I switch on the powersupply Power transistor getting blast.
I changed all capacitors and faulty componants on control board
The original powertransistor they used ON5134 and I trieng BUV48A.
I could not find datasheet of ON5134 ...
I attached here with the c-file and circuit and the working principle is given below;
Set any minimum and maximum temperature with the help of LCD display, by pressing switches S2 and S3. The maximum temperature will start from minimum temperature +10 degrees. If the temperature being...
PIC18F452 three phase inducion motor controller out put fluctuation
I have completed AN843 based 3phase motor controller and its working forward direction
is perfect, but when the reverse function, output fluctuating and fault light also blinking.
when I touch the reverse button or...
I am try to burn a file with G540 programmer and its showing some messages I attached as files.I am Using PIC18F452 micro controller. Hex file loading and burning successfully
but circuit not working. I also attached the hex file.please help
I have some doubt about a 220 volt three phase motor control circuit (micro controller based)
In circuit I gave 220 volt DC for three phase bridge circuit and 15 volt DC for control circuit.
if I give the control ground and power ground is separate (I meant the 15 volt and 220 volt is...
which is a suitable Programmer for P87LPC764 FD
Is it Possible Programming Parallel Programmer?
I have G 540 Programmer but I am so confusing and
Lost so many CHIPS.
program done with G540 but circuit not working.
I check FLASH MAGIC but, not supporting P87LPC device.
I can,t use any other...
