CrispTech announces the PowerTrans series of products from Moxa which meet the specific demands of power substation automation systems, traffic control systems and railway applications. The PowerTrans products are compliant with the relevant industry standards such as power substation automation systems (IEC 61850-3, IEEE1613), traffic control systems (NEMA TS2) and railway applications (EN50121-4).
Designed to be 19” rack mountable, these switches offer the new Turbo Ring technology with faster network fault recovery as well as Rapid Spanning Tree Protocols. Additional features include fan-less operation at a wide temperature range of -40 to 85C, dual redundant and integrated power supplies for high availability and high EMI noise immunity. These features allow these products to withstand extreme conditions and electromagnetic interference commonly found in power substation automation and rail systems. Maximum flexibility is achieved by modular design with high fiber optic and gigabit port density, along with optional rear or front wiring.
A major obstacle in developing substation automation systems involves interoperability. Often, devices from different manufacturers cannot communicate with each other due to different communication protocols. IEC 61850, an open communication standard in substation automation, is being applied to standardise all aspects of communication protocols between newer devices and legacy devices. The reliable network operation is essential for protection against electrical surge and EMI, extreme temperature variations and other environmental threats. IEC 61850-3 specifically defines environmental and electromagnetic interference (EMI) immunity for communication networks and substations systems.
The first of these models, the PT-7324 (24 x 100BaseX ) and PT7728 (24 x 100BaseX + 4Gb ports) will be released by CrispTech in the next few weeks.
