Variable speed drives (VSDs)
Motor control and energy management
AST supplies variable speed drive solutions for applications requiring controlled electric motor speed and torque.
VSDs adjust the electrical supply to compatible motors, allowing equipment to operate at speeds suited to changing process demands. Typical applications include pumps, fans, ventilation systems, conveyors and selected industrial machinery.
Why it saves energy
Correctly selected and configured drives can help reduce energy consumption in suitable variable-load applications, improve process control, support smoother acceleration and deceleration, and reduce mechanical stress.
From selection to fault-finding
AST can assist with drive selection, installation, configuration, upgrades and fault diagnosis according to the application requirements.
Works well with
-
Protect and convert power
Rotary phase converters (RPC)
Run three-phase machinery where only a single-phase supply is available. -
Keep running through interruptions
Water storage
Tanks, pumps and pipework for municipal water or harvested rainwater. -
Protect and convert power
Voltage stabilisers (AVR / AVS)
Keep sensitive equipment within a steady voltage range.
