One Solution for Railway Signaling Circuits

The IPS systems provide complete power solutions from one system to all signaling circuits. This SMPS based IPS system is extensively used in critical railway signaling applications. The IPS Systems meet the requirements of RDSO/SPN/165/2004, with applicable amendments.

There are three panels on the IPS

  1. AC Distribution Panel (ACDP)
    It is a combination of Inverters, Step-Down Transformers and Constant Voltage Transformer (AVR) regulators. There are maximum 3 inverters, 6 Step-Down Transformers and 2 AVRs in one AC Distribution Panel (ACDP).

  2. DC Distribution Panel (DCDP)
    This consists of DC-DC converters with different ratings. There is a provision to accommodate a maximum of 39 converters in one DCDP. All these converters work on 110V DC input which coming from FRBC panel. These converters feed power to different loads such as Axle Counters, Point Machines, Relay Internal and Relay External.

  3. FRBC Panel (FRBCP)
    FRBC Panel consists of maximum of 5 Switching Mode Power Supplies (SMPS) which are AC to DC converters (Rectifier module). Each module rated for 110V/20A. The maximum power rating of each module is 2.7kW. Up to five modules will be working in parallel load sharing mode in one IPS. Output of the FRBC Panel is connected to Battery Bank and to other two panels which are DCDP and ACDP.
