Masterflex® L/S® Precision Variable-Speed Drive with Remote I/O

New Product

New Product

Brushless motor for efficient, maintenance-free operation - digital display gives you repeatable control.

Flow rate 0,06 to 3400 ml/min - flow rate depends on drive rpm, pump head, and tubing size
Three digit LED display shows motor rpm - confirm speed setting at a glance
Reversible, maintenance-free brushless motor - purge tubing before or after pumping; pump fluid in either direction
Optional open-head sensor immediately stops the drive motor if the pump head is opened during operation
LED indicators confirm motor direction
Powerful motors let you stack 2 or 4 pump heads for increased flow rates and for multichannel applications
Separate speed and power (on/off) control - maintain speed setting while turning pump on/off
Stackable, splash-resistant ABS plastic housing; IP33 rated
Remote control capabilities via a DB9 female connector on back of drive
Speed control input: 4 to 20 mA or 0 to 10 VDC
Pump direction (CW/CCW) via open collector or contact closure
Start/stop via open collector or contact closure
Membrane keypad for easy up-front control of speed, direction, and start/stop

These accurate analog console drives have powerful brushless motors, speed display, and ±0,25% speed control for precise flow regulation - ideal for metering applications. Remote speed control requires DB9 male connector or cable assembly. Use remote connector for control of start/stop via contact closure or open collector (5 V TTL); control start/stop via footswitch or handheld remote.
