The rear of the optional rack has five individual AC inputs supplied through an IEC320 C15 line cord or through optional screw terminal blocks. The PMBus communications interface is connected via two RJ45 connectors, and other control signals are connected to the 40-pin Samtec IPD1-20-D connector. The output is supplied via two sets of bus bars, each of which can provide up to 200A. Up to two racks can be paralleled together with load sharing.
