UPS Trainer Model ETR 052

Sci-tech UPS Trainer Model ETR 052 is a very versatile UPS training system, has been designed to explain a switching based Uninterrupted Power Supply. The product is designed keeping in mind that a student can understand each block of UPS-01 in a very easy way.

Item Description

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. Automatic Voltage Regulator is presented in such a way that a student can readily understand its functioning and pin configuration. Test points allow the analysis and monitoring of the signals in different sections. By using the fault simulation method, it is possible to introduce the most common breakdown and their rectification.
