Overview

Power Range - 45kW - 1.9MW

Global Power Supplies - 200/400/575/690Volts

The Unidrive SP Modular drives range offers the same advanced feature set as our panel mount drives but with additional power system flexibility; the drives may be arranged to provide a common DC bus system with or without an active front end (regenerative, 4 quadrant operation). Very high current motors may be controlled using a multi-drive modular arrangement.

Applications

The Unidrive SP Modular drives are suitable for applications in both commercial and industrial applications where power scheme flexibility and regenerative energy saving provides an operational advantage. Typical applications include:

• Energy saving with very high power fans and pumps
• Metal production and processing
• Large cranes
• Automotive testing such as car, engine and gearbox dynamometers
• Web control and winding
• Conveying and processing of bulk materials
• Pulp and paper processing
• Marine applications
• Photovoltaic
• On shore drilling 

Benefits

Unidrive SP Modular drives enjoy the same advantages as the Panel Mounting drives with the following additional benefits:

• Higher power motors are controlled using Unidrive SP modules connected in parallel. This is an economic and compact solution that simplifies installation and improves serviceability
• Allows you to use a DC bus system to recycle energy between simultaneously braking and motoring drives such as in a winder/unwinder configuration
• Minimise harmonics with 12, 18 and 24 pulse operation to allow you to meet and exceed stringent supply regulations
• Eliminate harmonics and deliver clean power back to grid using an active front end
