MSDi 3 Series - Surge Diverter |
||||||||||||||||
|
The MSDi surge diverter is designed to provide point-of-entry
protection against power surges caused by external sources such
as lightning strikes and substation switching. Common-mode
protection is available for sites remote from the M.E.N. point
including industrial sites and rooftops in multi-storey
buildings. The MSDi surge diverters utilise MOV protection for
both differential and common-mode protection. Multiple MOV
devices are used in parallel for primary circuit redundancy. The
status of protective devices is continuously monitored and
displayed using LED bar-graph indicators. All MOV devices are
thermally fused and isolated by ceramic fuses. The MSDi is designed for simple maintenance. Instead of a myriad of modules, wires and connections, the MSD uses a single PCB module with all surge and alarm components mounted to it. Circuit current does not flow directly through the PCB, giving excellent tolerance to overload in the case of series connection. In the event of a surge failure, the whole PCB is simply replaced. MSDi unit are provided with an alarm relay. The alarm function provides a summary alarm output for protection degradation as well as power failure. The alarm may be configured to indicate either partial or total protection failure. The level of protection remaining is indicated by LED bar-graph indicators on the front panel. A summary alarm relay contacts provide remote signalling to remote equipment.
