Non-source adjustable constant electronic load circuit
In power supplier industry, the electronic load is the necessary R&D or production equipment of all manufacturers, most electronic loads in the market are very expensive, and they need the power supplier to work. This article supplies one kind of circuit scheme, so that the readers can make the CC mode passive adjustable electronic load by themselves, the input voltage range is 3 to 30V, the input current range is 0.01A to 10A. The circuit is as shown: S1 is the load switch, you can disconnect the whole load by S1. N1B is the quasi-constant current source circuit, the N1B can make the 432 toproduce the1.25V standard and it can also make the current of 432 unchanged even if the input voltage changes. In the CC mode, R8 is the current sampling resistor to feedback the current and make the load current constant. Resistance R6 is the coarse adjustment resistor, resistance R7 is the fine adjustment resistor.
