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 ...
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 measured is more than the preset maximum temperature, relay RL1 de-energises and the heating...
This project is working well. But need some changes according to my application.
In this circuit Heating element Off and On similarly when the temperature greater than set temperature and
less than the set temperature.In my application, I need only one command which is;
"If the measured...
I attached here with the c-file and circuit and the working principle is given below;
