Power Supply Module
Redundant power supply module
(NP1S-22/NP1S-42)
Redundancy of the power supply has been realized by supplying the power from multiple (up to 3) power supply modules. The redundant configuration of the power supply section with the highest failure rate can improve the system reliability.
Small capacity power supply module
(NP1S-81/NP1S-91)
The use of the 100V AC or 200V AC small capacity power supply module (single slot) on the 3-slot and 6-slot basis allows effective use of one slot.
