  • Design Guideline: AAT3190 Positive/Negative Charge Pump
    independent output voltages. The AAT3190 charge pump controller regulates and provides positive (VOP) and negative (VON) voltage bias supplies for active matrix thin-film transistor (TFT) displays, liquid-crystal displays (LCDs), or other applications. The AAT3190 evaluation board can be configured
  • Pump Controls
    and more efficient operation of variable-volume pumps, and reduces the number of valves in a circuit. The basics of electronic pump control are rather straightforward. A programmable controller, PC, microprocessor, potentiometer, or other such device provides a signal to an electronic driver board
  • Pump Control with Variable Frequency Drives (.pdf)
    While the inefficiency of driving a car with the gas pedal to the floor and then controlling your speed using the brake is obvious to any driver, many facilities use that very same approach for pump control. Flow control with throttling or restrictive devices, as is often done, sacrifices energy
  • Danfoss digital display unit simplifies assembly and maintenance of booster pump systems
    A California booster pump integrator has replaced conventional pressure gauges with the MBD 1000 digital display unit and MBS 3000 pressure transmitters, saving costs in assembly, testing, maintenance and service. Danfoss digital display unit simplifies assembly and maintenance of booster pump
  • Cooling Towers and Boiler Controllers FAQs
    the controller even when the power switch on the front panel is turned OFF. The front panel should never be opened before power to the controller is REMOVED. (Top). 3. Why does the controller overshoot the set point?. A. Pump is too large: Calculate the flow rate required. The metering pump should be set

    the rotor to the start position. Then once a capacitor is fully charged, (which takes less than 1 W), the pump starts. This minimizes cycling during unsuccessful starts. Following its programming, the motor controller checks every 3 sec to see if it needs to alter its operating point on the pump's
