GPC 系列直流電源供應器是一部攜帶式可調整的多功能儀器，特別設計應用在電源操作的放大器，邏輯線路，正負電壓誤差非常小的精密儀器系統的追蹤上，或需要用到三組獨立電源的單體線路上，可稱得上是一部非常實用又方便的儀器。GPC 系列主要由兩組相同、獨立、可調整的直流電源供應器組成，從前面板的 TRACKING 選擇開關可選擇三種模式：獨立輸出、串聯輸出和并聯輸出。在獨立模式(INDEP)狀態時，二組主控(MASTER)、副控(SLAVE)輸出電壓、電流為獨立分離輸出，而其輸出端子到機殼或主控(MASTER)輸出端子到副控(SLAVE)輸出端子的隔離度(ISOLATED)有 300V。當在追蹤模式(TRACKING)狀態時，主控輸出端與副控輸出端會自動的連接成串聯模式(SERIES)或并聯模式(PARALLEL)，不需另外從輸出端接任何導線；在串聯模式時，調整主控輸出電壓(+)即有等量的副控電壓(-)輸出；并聯模式時，調整主控輸出電流，則主控輸出端即有二倍的電流量輸出。

本系統采用電動機電樞供電回路串接采樣電阻的方式來實現對小型直流有刷電動機的轉速測量。該系統主要由二階低通濾波電路,小信號放大電路、單片機測量顯示電路、開關穩壓電源電路等組成。同時自制電機測速裝置,用高頻磁環作為載體,用線圈繞制磁環,利用電磁感應原理檢測電機運行時的漏磁,將變化的磁場信號轉化為磁環上的感應電流。用信號處理單元電路將微弱電信號轉化為脈沖信號,送由單片機檢測,從而達到準確測量電機的速度的要求。In this system, the sampling resistance of armature power supply circuit is connected in SERIES to measure the speed of small DC brush motor. The system is mainly composed of second-order low-pass filter circuit, small signal amplifier circuit, single-chip measurement and display circuit, switching regulated power supply circuit and so on. At the same time, the self-made motor speed measuring device uses high frequency magnetic ring as the carrier, coil winding magnetic ring, and electromagnetic induction principle to detect the leakage of magnetic field during the operation of the motor, which converts the changed magnetic field signal into the induced current on the magnetic ring. The weak electric signal is transformed into pulse signal by signal processing unit circuit, which is sent to single chip computer for detection, so as to meet the requirement of accurate measurement of motor speed.
