NT66XX Transformers

Transformer-low power-T/J hybrid units for relay and SSI signalling systems 650V/230V/110V/50Vd.c.

Signalling transformers provide the interface between a 650V or 230V power system and a 110V signalling system. Outputs include multiple 110V / 135Va.c. and 50Vd.c. for signalling or 230V for telecoms, all depending on part number chosen.

The transformers comply with NR/L2/SIG/30007 and allow system compliance with Electricity at Works Regulations and NR/SP/ELP/27243.

They provide 8kV minimum impulse withstand voltage in compliance with BS7671 to provide additional protection against ground potential rise in areas with d.c. or a.c. traction systems.

NQ66xx Transformer/Rectifiers
Transformer/Rectifier for relay and SSI signalling systems 650V/230V/120Vd.c.
Signalling Transformer/Rectifiers provide the interface between a 650V or 230V power system and 120Vd.c. points machines. Versions are available for multiple 120V points machines. The number of points machines that can be driven by one transformer/rectifier depends on the transformer/rectifier part number chosen and the type of point machine.
The construction of the transformer in the transformer/rectifier allows system compliance with Electricity at Works Regulations and NR/SP/ELP/27243. The internal transformer complies with NR/L2/SIG/30007.
The internal transformers provide 8kV minimum impulse withstand voltage in compliance with BS7671 to provide additional protection against ground potential rise in areas with d.c. or a.c. traction systems.
