An intelligent method for Dynamic Inrush Restraint

•   Makes secondary switching (one PDU

transformer) reliable.

•   Eliminates the need for complex inverter control

schemes.

•   Maintains true independence between UPS

systems (higher reliability).

•   Keeps inrush value lower than 1.2x.

•   Exceeds the ITIC and CBEMA curves standards

for critical loads, see figure 4 above.

•   Smoothly transfers the load without creating

unnecessary voltage discontinuity and

disturbances to the load.
