30 kW 525 V Variable Speed Drive, 46.4 A, Three-Phase

Description

Overview

Where the pump set runs on 525 V three-phase, this 30 kW (40 HP) variable speed drive is the one that fits. It is rated at 46.4 A and works by altering the frequency to the motor, so a large pump can run at the speed the duty needs rather than full speed all the time. Check your site supply voltage before you order.

On a big 525 V set the benefits are bigger bills avoided: less starting shock, less wear on the column and bearings, and lower power use at part load. For the same size on 380 V use the 30 kW 380 V variable speed drive, and for a 37 kW motor on 380 V look at the 37 kW 380 V drive.

Key features

• Rated 30 kW (40 HP) at 46.4 A on a 525 V three-phase supply
• Varies motor speed by changing output frequency
• Soft start limits shock to the motor and pipework
• Saves electricity when the pump runs under full load
• Suits 525 V pump sets and constant-pressure systems
• Supply voltage must match the motor plate

Where it works

525 V supplies are standard on many South African mines, so this drive belongs on large dewatering sets, slurry and process water pumps and shaft-bottom stations in Mpumalanga, Limpopo, the North West and the Northern Cape. It also suits big borehole sets where the site was wired for mining voltage. Look through our other pump controllers and VSDs to cover the rest of your motors.
