GPC 系列直流電源供應(yīng)器是一部攜帶式可調(diào)整的多功能儀器，特別設(shè)計(jì)應(yīng)用在電源操作的放大器，邏輯線路，正負(fù)電壓誤差非常小的精密儀器系統(tǒng)的追蹤上，或需要用到三組獨(dú)立電源的單體線路上，可稱得上是一部非常實(shí)用又方便的儀器。GPC 系列主要由兩組相同、獨(dú)立、可調(diào)整的直流電源供應(yīng)器組成，從前面板的 TRACKING 選擇開關(guān)可選擇三種模式：獨(dú)立輸出、串聯(lián)輸出和并聯(lián)輸出。在獨(dú)立模式(INDEP)狀態(tài)時(shí)，二組主控(MASTER)、副控(SLAVE)輸出電壓、電流為獨(dú)立分離輸出，而其輸出端子到機(jī)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(dāng)在追蹤模式(TRACKING)狀態(tài)時(shí)，主控輸出端與副控輸出端會(huì)自動(dòng)的連接成串聯(lián)模式(Series)或并聯(lián)模式(PARALLEL)，不需另外從輸出端接任何導(dǎo)線；在串聯(lián)模式時(shí)，調(diào)整主控輸出電壓(+)即有等量的副控電壓(-)輸出；并聯(lián)模式時(shí)，調(diào)整主控輸出電流，則主控輸出端即有二倍的電流量輸出。

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.
