Product Code : SCL-EELE-12293
Indian Lab Suppliers supplies the SMPS trainer Kit (For Computer) (Product ID: 12293) as part of its electronics engineering lab equipment range. It is a computer-type switched-mode power supply built around an IC 494 PWM controller, on an enlarged PCB for study and fault finding.
Quick Answer
The trainer takes 170-260 V AC, 50 Hz (about 150 W input) and produces +5 V, −5 V, +12 V and −12 V outputs plus a power-good signal, brought out on six pairs of output leads. The IC 494 PWM controller sits in a socket, and a 12 V, 0.14 A brushless fan cools the board. Students trace each section, measure voltages and waveforms at test points and remove components to study faults, using a 3½-digit multimeter, 15 MHz CRO and 8 A variac (not included). The primary side runs at rectified mains voltage, so work with the supply off and capacitors discharged.
