About This Product
Students set the output with the potentiometers and switch through the 16 internal load steps to test the regulator's performance, then use the same board as a stabilised supply for an external circuit. Test sockets on the panel give access to the waveforms, and operating instructions cover the object, theory, design procedure, report suggestions and book references. The SCR Regulated D.C. Power Supply can be dispatched from India to Maldives, United States, Vietnam, Saint Lucia, Georgia and Tunisia.
