MAKELSAN UPS SOLUTION FOR RAILWAY INFRASTRUCTURE

In recent years, more and more countries are giving more importance to sustainable mobility, investing in public transport, and encouraging citizens to reduce the use of the most polluting cars. In this context, Makelsan aligns itself with the greater demand for sustainable mobility as uninterruptible power supplies play a fundamental role for companies that must offer citizens an impeccable service and avoid interruptions and therefore delays. Makelsan’s three-phase online UPSs offer low voltage power grid solutions that ensure maximum performance for even critical applications, such as railways.

The development of the railway system has brought convenience to people’s lives, and reliable and high-quality power resources are essential for the modern railway system because even minor disturbances in the power supply or quality can create major network disruptions. Network disruptions in the railway system are not just inconvenient; they are also serious threats to health and safety. To avoid power disruption in the rail network, reliable UPS backup power is needed.

Makelsan’s transformer-less and transformer-based products with adaptability to different power sources (single-phase, three-phase, with or without neutral) are able to meet the most complex requirements. Also because Makelsan UPS has the following three characteristics, it is suitable for railway industry applications

1. Reliable

It has an N+X parallel redundancy design, where the total load demand is met by all the UPS sharing the load between themselves equally. If one of the UPS fails, the remainder can continue supporting the load, which helps achieve higher availability and MTBF (mean time between failure) lowering the threat of power failure.

2. Easy O&M

It’s hot-swappable so removing or adding modules will not affect the general operation. Additionally，the internal power modules are independently controlled. Therefore, a problem with one of the modules will not affect the operation of the whole machine. While a traditional UPS power supply fails, it must be repaired by professional technicians.

3. Money-Saving

In the preliminary planning, customers usually underestimate or overestimate the ups capacity. Makelsan UPS power supplies effectively solve the problem by modular design， allowing you to build and invest in stages to reduce the initial purchase cost. You can increase the load & power module as your business grows. With high power density, small size, lightweight, it also has the advantages of convenient transportation, installation, and material saving.

Over the years, Makelsan has delivered rail-specific power protection solutions for many years, and has extensive experience designing, delivering, and supporting standard and specific UPS solutions for above-ground and underground rail installations around the world.
