2.2 kW 525 V Variable Speed Drive, 3.6 A, Three-Phase

Description

Overview

If your small pump runs on a 525 V three-phase supply, this 2.2 kW (3 HP) variable speed drive is the match. It is rated at 3.6 A and controls the motor by altering the frequency, so the pump can be slowed or sped up to fit the duty. Most drives in the shops are made for 220 V and 380 V, so a true 525 V unit saves a lot of searching.

These drives are used on 525 V pump sets and on constant-pressure systems, where they soft start the motor and follow demand. The result is less wear, less shock to the pipework and lower power use at part load. For 380 V motors of the same size, the 2.2 kW 380 V variable speed drive is the right choice.

Key features

• Rated 2.2 kW (3 HP) at 3.6 A on a 525 V three-phase supply
• Controls pump speed by changing output frequency
• Soft start protects the motor and the pipework
• Running slower at part load saves electricity
• Suits 525 V pump sets and constant-pressure systems
• Voltage must match the motor plate, so check it first

Where it works

Look for 525 V supplies on mines and heavy industrial sites around Mpumalanga, the North West and Limpopo, where small transfer, sump and water-service pumps are common. A drive this size handles those smaller duties, while the heavy dewatering pumps need something bigger such as the 18.5 kW 525 V variable speed drive.
