易于使用的模擬驅動器提供精確的速度控制和遠程控制能力適合計量，進料和傳輸應用。

10圈電位器，精確的，準確的速度控制。鎖定桿可以鎖定您的確切速度設置。

獨立的速度控制和開/關/反向開關帶慣性中心和綠色LED電源指示燈。保持速度設定開/關而轉向泵。

DB9母連接器背面的驅動器速度控制輸入：4至20 mA，或2至10 VDC遠程控制功能，通過啟動/停止通過集電極開路或觸點閉合。

可逆電機吹掃管之前或之后抽泵流體在任一方向。

1/10-hp可逆電機具有軟啟動和反電動勢為±2％的速度控制。促進運行平穩，使用壽命長。

可堆疊的ABS塑料外殼，IP23防護等級評分液體潑濺，易于擦洗。6英尺（1.8米）的線

這些模擬??驅動器的設計，用理想融入實驗室或過程的應用，需要精確的流量控制的可靠性和易用性。遠程速度控制要求DB9公頭連接器07595-45。使用連接器也為遠程控制啟動/停止通過觸點閉合或集電極開路（5 V TTL）或控制啟動/停止通過腳踏開關77595-35 07595-45。訂單連接器和配件右腳踏下。

Easy-to-use analog drives offer precise speed control and remote control capability—ideal for metering, feed, and transfer applications.

10-turn potentiometer for precise, accurate speed control. Locking lever enables you to lock in your exact speed setting.

Separate speed control and on/off/reverse switch with inertia center and green LED power indicator. Maintain speed setting while turning pump on/off.

Remote control capabilities via DB9 female connector on back of drive—speed control input: 4 to 20 mA, or 2 to 10 VDC; start/stop via open collector or contact closure.

Reversible motor—purge tubing before or after pumping; pump fluid in either direction.

The 1/10-hp reversible motor has soft start and back EMF for ±2% speed control. Promotes smooth operation and long service life.

Stackable ABS plastic housing is IP23 rated for splash resistance and easy wipedown.

6-ft (1.8-m) line cord

These analog drives are engineered for reliability and ease of use—ideal for integration into lab or process applications requiring precise flow control. Remote speed control requires DB9 male connector 07595-45. Use connector 07595-45 also for remote control of start/stop via contact closure or open collector (5 V TTL); or control start/stop via footswitch 77595-35. Order connector and footswitch under accessories at right.
