POWER and automation technology group ABB has announced the release of a new low voltage AC drive, specifically targeted at pump and fan applications.
ABB said it designed the drive to be fast to install and commission for pump and fan applications. Built-in PID controllers are used to vary the drive’s performance in response to changes in pressure, flow or other external data, modifying the performance according to the needs of the application.
A pump and fan control (PFC) feature modulates the speed of the main pump or fan and brings any auxiliary pumps or fans on line as necessary, ABB said.
The drive is also designed to manage switching between pumps or fans to ensure they are all used to the same extent over the long term.
In addition, the drive includes soft pump and fan control (SPFC) which further reduces unwanted pressure peaks in pumps and pipelines.
According to ABB, the drive’s internal fan is controlled by software to reduce losses, further improving energy efficiency.
