The introduction of new Rolling Stock driven by AC Traction Motors, has resulted in Electro Magnetic Capability (EMC) issues with conventional signalling in the United Kingdom. This can delay the testing and launch of these new trains on key inter-city routes.
Park Signalling Ltd have developed a solution to minimise the effects of this and other electrical surges, on Solid State Interlocking (SSI) signalling systems.
The Isolating Surge Protection Unit (ISPU-E) for SSI Data Links is an improved surge protection unit that incorporates a transformer to greatly enhance immunity to common mode surges and voltages, protecting the Data Link Modules (DLM) from displaying faults or even failing.
Park Signalling’s ISPU is the only ISPU device with Network Rail approval (PADS no. 086/047164).
The ISPU-E SP01 module is designed to meet the requirements of BS EN 50125-3:2003 for equipment housed in a cubicle, (Altitude A1, Temperature Range T1).
All electrical connections are made via the 11 pin (B11A) plug base, in accordance with GS/ES 1937.
