Because the PIM option provides a second output, the Intelligent CableUPS can function as
an N+1 redundant supply system. The PIM also provides programmable current limits for
two output channels, which protects system components by shutting down the load during
overcurrent and short circuit conditions. Adding a PIM to a secondary power supply enables
both power supplies to be connected in a “dual redundancy” configuration to protect two
critical loads.
