INTEGRATED POWER SUPPLY SYSTEM
The IPS systems provide complete power solutions from one system to all signalling circuits. This SMPS based IPS system is extensively used in critical railway signalling applications. The IPS Systems meet the requirements of RDSO/SPN/165/2012 (Version 3.0).
There are three panels on the IPS
AC Distribution Panel (AC Panel)
It is a combination of Inverters, Step-Down Transformers and Constant Voltage Transformer (AVR) regulators.
DC Distribution Panel (DC Panel)
This consists of DC-DC converters with different ratings. 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.
FRBC Panel (SMPS Panel)
FRBC Panel consists of maximum of 5 Switch Mode Rectifier Module (SMR) which are AC to DC converters (Rectifier module). Each module rated for 110V/20A. 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 DC Panel and AC Panel.
