Speed controller used for energy saving

In a pumping or ventilation installation, the motor, supplied direct from the mains, rotates at its nominal speed. The flow rate can be regulated with manual valve or speed controller. The speed controller enables significant electricity savings to be made, which is not the case of the manual valve. MAQ-WATT demonstrates this phenomenon by comparing the consumption in the two situations.
Educational objectives
• Energy savings by speed controller demonstrated.
• Creation of the configuration of a speed controller with software.
• Using an energy measuring unit.
• Using a clamp ammeter.

2 types of operation are offered:
• Direct supply of the pump with a contactor and regulation of the water flow with manual valve.
• Supply of the pump with controller and regulation of the flow rate by variation of the speed of rotation.
A measuring unit compares, among other things, the 2 powers absorbed.
A float provides a visual indication of the flow rate.
