IEC 61850-3 and IEEE 1613 (power substation) compliant, Up to 4 Gigabit uplinks ports, Modularized design for flexible and scalable networks. The IT-PSS-8217 series are modularized advanced managed gigabit L3 switches. They comply with industrial standards such as the communication network of IEC 61850-3 and IEEE 1613. Hence they fully meet the requirements of intelligent substations. They can provide 24/48 VDC or 110/220 VDC/VAC redundant power input, which make the power supply on-site more flexible. Rear panel cabling design can meet the requirements of power system so that they can be widely applied in the industrial fields such as electrical power, transportation and energy.
