Specialists in Rail Electronics

Rugged electronic components provide only part of the solution for the electronics systems used in new rail industry designs and legacy equipment. That is why Charcroft Electronics offers a team of product specialists who understand the challenges of designing, upgrading or maintaining electronics systems in harsh environments and over an extended lifecycle.

Rail-Approved Electronic Components

A strong linecard of products offers rugged components from some of the world’s leading component manufacturers, as well as specialist suppliers. This includes products which are approved to key rail standards such as EN50155, EN50121, EN6100 and EN60695 in addition to BS6853, and a range of NF fire and safety approvals.

Customisation simplifies system upgrades

For upgrade and MRO projects, customisation of a standard product often enables new components to be installed with little or no re-engineering of the legacy system.

Customised Rail Electronics

Customising a standard product can eliminate or minimise the amount of re-engineering required to upgrade systems by replacing legacy components with new alternatives. Examples of previous challenges have included solutions such as:

  • Full-scale product development to small custom modifications
  • Eliminate of re-working of metalwork
  • Conversion of chassis mounting to DIN rail mounting
  • Non-standard output voltages
  • Customised fixings for power supplies
  • Secondary reset circuit added to a power supply
  • Adapted base-plates for circuit breakers
