TDK-Lambda UK has improved load sharing in N+1 redundant powers, claims the Devon-based firm.
"In systems that are required to operate with high reliability, it is often necessary to operate multiple power supplies in parallel," said Lambda CTO Andy Skinner. "Should one power supply fail, a sufficient number of power supplies remain in operation for the system to continue to function - this is known as N+1 redundancy."
