The ETB-185 is a dedicated SMPS (Switched Mode Power Supply) Trainer Kit designed to study, analyze, and troubleshoot the working of SMPS circuits used in computer power supplies (ATX/SMPS units). This educational model provides students, trainees, and technicians with practical exposure to real-world computer SMPS architecture, making it ideal for vocational labs and technical institutions.
The trainer simulates the structure and operation of a standard computer SMPS unit, with clearly labeled functional blocks such as input rectifier, chopper section, pulse-width modulation control, switching transformer, and regulated DC outputs (+5V, +12V, -12V, etc.).
Key Features:
Based on standard computer SMPS circuitry
Block-wise layout: input filter, bridge rectifier, PWM controller, driver, transformer, and output rectifiers
Built-in safety features and test points for live waveform analysis
Fault simulation facility for hands-on troubleshooting practice
Ideal for electronics and computer hardware service training
