From power switching to power management

摘要

It was eight years in development and represented one of the biggest investments in a single product by ABB - the SACE Emax 2 is described by the company as an air circuit breaker turned power manager, capable of controlling the sequencing of loads in the most complex of automated networks - and saving huge amounts of energy in the process. Les Hunt reports. Emax 2 is targeted at those applications where the protection and control of large amounts of energy is undertaken in a low-voltage environment. Claimed to be the first low-voltage circuit breaker with integrated energy management functions, an Emax 2 retrofit has the potential to save significant amounts of energy; indeed, ABB claims that for a typical building, you could expect a reduction in peak power of up to 15 percent.
