求翻译：利用MOS管、运放电路和单片机系统制作一个恒流电子负载，功率小于18W，最大工作电流1A。利用单片机系统进行恒流电流值设置，且能监测系统被测电压电流的实时值，具有过压保护功能。是什么意思？

Mos tube op amp circuit and microcontroller systems to produce a constant current electronic load power is less than 18w, maximum operating current 1a. SCM system, the constant current value is set, capable of monitoring system measured voltage and current real-time value, the overvoltage protection

Use MOS tube, and the circuit and single-chip phone system make a constant flow, power electronic loads, less than 18 W Maximum operating current A 1. Take advantage of single-chip system for constant-current value is set, and can monitor the system voltage and current are measured in real-time valu

Using the MOS tube, transports puts the electric circuit and the monolithic integrated circuit system manufactures a constant flow electron load, the power is smaller than 18W, biggest operating current 1A.Carries on the constant flow magnitude of current establishment using the monolithic integrate

Using MOS tubes, amplifier circuit and single-chip microcomputer system produced a constant-current electronic loads, power is less than 18W, maximum operating current of 1 a. Using single-chip microcomputer system for constant-current current value settings, and real-time monitoring system measured
