SMART - Pump

Features

SMART-Pump (SP) variable speed drives are full-featured dedicated drives for parabolic load applications like pumps, fans, and chillers. SP drives have a wide range of integrated features like multi-pump control, dry run protection, sensor-less flow, and energy calculation, pump cleaning, fire override mode, frost, condensation, and hammer effect protections to meet the needs of a pump, fans, and chillers for modern buildings.

SP series variable speed drives cover motors with the following ratings:

- 2.2kW...160kW, 380V - 440V three-phase AC

- 2.2kW ... 45kW, 220V three-phase AC

Benefits

Robustness

- Stable operation under main input voltage fluctuations increases the robustness of the drive-in difficult environment

- Built-in category C3 standard EMC filter ( ≥ 11kW ) helps in better immunity against signal noises and supports longer connection cables

Improved Energy Savings

- Integrated Eco-mode increases energy savings in low dynamic load applications such as pump and fan

- Improved special PID control with sleep mode helps to save more energy for pump application

Special Functions

- Multi-pump control: Control 4 pumps (3 without and 1 with external I/O card)

- Sensorless energy and flow meter: Measure energy and flow without an external sensor

- Pump cleaning function: Clears the blockage in the pump

- Reduces the maintenance requirements

- Fire override mode: Keeps the critical fans and pumps running in case of fire in a building

- Dual Ramp: Separate initial and final ramp ratio optimizes the motor start and stop

Pump protections

- Dry run protection

- Frost protection

- Condensation protection

- Hammer effect protection

- Over-voltage protection

- Over-current protection

- Overload protection

- Phase-loss protection

- Short-circuit protection
