UPS Trainer For Electrical Lab Training

The UPS trainer is a very versatile training system,has been designed to explain a very interesting and frequently used switching based power supply - The UPS (Uninterrupted Power Supply). The product is designed keeping in mind that a student can understand each block of UPS in a very easy way. Various test points have been provided so that one can check inputs and outputs of each block contained. Being different from a conventional block diagram internal structure of blocks is also shown. AVR (Automatic Voltage Regulator) is presented in such a way that a student can readily understand its functioning and pin configuration. Since UPS is different from an inverter because its switching changeover time is less than 3 mS which is very less so a computer system doesn't get reboot. In depth explanation of PWM switching technology, which is one of the most important feature of UPS A Low cost product demonstrating all basic concepts of UPS Various test points are provided so that one can easily measures the voltages of different sections Designed considering all safety standards Provided with a detailed Operating manual 2 Years warranty Technical Specifications Input : 190 to 260 V 10%, 50 Hz Output : 230 V Transformer specifications Input : 12 - 0 - 12 V Outputs :  0, 190, 220, 240, 260 V 18 - 0 for battery charging Dimension (mm) : W 365 × D 265 × H 120 Weight : 5 Kg (approx) Experiments than can be performed Study of PWM Technology To understand the overall functioning of UPS Trainer Study of AVR transformer section of UPS To study the UPS circuit in load condition To identify different faults and to study the systematic procedure of their troubleshooting in UPS circuit
