Constant current sources are a type of power source commonly used in electronic instruments and equipment. Generally, constant current sources often have shortcomings such as small adjustment range and poor stability. The digitally controlled DC current source designed in this paper can reduce the output error caused by components aging, temperature drift and other reasons.
The current source supports 0-20mA, 0-2mA, 0-200uA three-speed adjustable, output current can be preset, output current signal can be directly displayed, over-voltage and over-current protection circuit, buzzer alarm circuit when disconnected, accurate measurement Resistance and other functions, the accuracy of the current is 0.0%~0.1%, and the measurement resistance error is 0.0%~1.0% ohm. The hardware circuit adopts MSP430F5529 low-power single-chip microcomputer as the control core. The closed-loop control principle is adopted, and the circuit forms closed-loop negative feedback to stabilize the flow, finally achieving high precision, good stability and wide output range.

BIOTEPT NEMA Brake AC motors stop equipment when power to the motor is stopped and are used for applications that require rapid stopping and holding action. They also provide braking as a safety measure if power is cut abruptly. Motors are commonly used on conveyors, door operators, hoists, machine tools, and speed reducers that require quick stops or to prevent equipment rollback
