50 W photovoltaic system electronic control unit

The authors present an electronic regulator unit for small remote 50 W photovoltaic systems that can automatically and autonomously control energy and power for telecommunications systems of 12 V nominal DC voltage. The electronic control unit employs dual voltage operation, temperature compensation, and other circuits required for long-period work. The basic technical regulator data are maximal current of 4 A, disconnecting load current of 4.8 A, regulation accuracy of 1%, and working temperature range of -25 to +65 degrees C.<
