Gigabit Ethernet Switch for Power Substation

Gigabit Ethernet Switch for Power Substation

IEC 61850-3





The IPS-G803SM Managed Gigabit Ethernet Switch is designed to meet the demands of power substation systems and is fully compliant with the requirement of IEC 61850-3 and IEEE 1613. The switch provide a variety of redundant functions to increase the reliability of your communications system, including redundant and isolated power supplies (24/48 VDC) and 110/220 VDC/VAC), STP/RSTP/MSTP and ITU-T G.8032 Ethernet Ring Protection Switching (recovery time<50ms). It is compatible with other switches in the network for ring protection. The proprietary μ-Ring (with recovery time of less than 20ms) can work with a variety of our industrial managed switches for ring protection. The switch also provides many functions, such as Web management, SNMP, IGMP, VLAN, LACP, QoS, Security, IPv6, bandwidth control, port mirroring, cable diagnostics and Green Ethernet.
