PUMPSMART PS220
Provides the next level in intelligent pumping by using a standard variable frequency drive and directly embedding pump specific algorithms onto the drive. The PS220 drive is a microprocessor based Direct Torque Controlled (DTC) adjustable speed AC drive. Pump specific algorithms combined with the advantage of sophisticated high-performance control of AC motors make it the ultimate variable speed drive solution for any pumping application.

PUMPSMART PS10-PS20
Developed for fixed speed pumping applications, the PumpSmart PS10 and PS20 Pump Load Monitors offer unsurpassed protection for underload and overload conditions that most often result in mechanical seal damage or pump failure.
OVERVIEW
|
Simplicity No external process sensors required Reliability & Safety Protection from dry running and overload conditions means reduced maintenance and downtime Flexibility 110 – 575 AC Voltages Up to 999 FLA Motor sizes |
Details
|
PS10 Pump Load Monitor The PS10 offers single underload or overload condition protection for pumps up to 40 HP (50 Amps MAX). Alarm set points can be entered either manually or automatically set using the Auto-Set functionality during normal operation. PS20 Pump Load Monitor The PS20 offers two underload and two overload condition protection functions (four total) as well as the ability to output pump load through an integrated 4-20 mA output. A six button keypad and LCD readout enables greater configuration and operation options. The PS20 can be applied on motors up to 999 F.L. Amps |
Pump Load Measurement
The instantaneous power supplied to the pump by the electrical motor is monitored by measuring the input power and by calculating the motor power losses with a proprietary algorithm. The value of the real motor shaft power is used to accurately determine overload and underload conditions.
