22 kW 525 V Variable Speed Drive, 36.8 A, Three-Phase

Description

Overview

This 22 kW (30 HP) variable speed drive is made for pump sets on a 525 V three-phase supply, and it is rated at 36.8 A. By altering the frequency to the motor it lets a large pump run at the speed the duty needs, rather than at full speed all the time. 525 V is the voltage you meet on many mines, so the drive saves you the trouble of stepping the supply down.

A drive on a 525 V pump set soft starts the motor and follows demand, which reduces wear and cuts power use at part load. For the same power on 380 V use the 22 kW 380 V variable speed drive, and for a 30 kW motor on 525 V the 30 kW 525 V drive is the next size up.

Key features

• Rated 22 kW (30 HP) at 36.8 A on a 525 V three-phase supply
• Controls motor speed by changing output frequency
• Soft start limits mechanical shock to the pump and column
• Saves electricity when the pump runs below full load
• Suits 525 V pump sets and constant-pressure systems
• Confirm the supply voltage on site before you order

Where it works

Mines in Mpumalanga, Limpopo and the North West run 525 V reticulation, and large pumps for dewatering, process water and tailings feed are the typical loads. Deep borehole sets on big farms and water schemes that share a 525 V supply also use drives of this size. Explore our other pump controllers and VSDs to match each motor on the site.
