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 ...
