The company says its new multiplexing system utilizes a combination of advanced hardware and software to provide controls of multiple motors from a single vfd. The company says its new system can be applied to multi-pump or multi-fan systems wherein system flow or pressure can be satisfied by a combination of constant-speed and variable-speed operation. The company explains its multiplexing system utilizes special motor sequencing software to enable a single vfd to operate one of several ac motors at variable speed in response to system demand. When demand exceeds the capacity of the one pump or fan, the Multiplexer System transfers the motor from the vfd to ac line power, it says.
