In the functionally equivalent card, use of power bricks/modules from reputed suppliers like Vicor, TDK Lambda, Cosel, Recom etc. of different voltage and power level with suitable cooling and protection PROVIDED.

KU A915 POWER SUPPLY CARD

ALG Power Supply…KU A915 B01: ALG power supply occupies 12T width (3 slots) and is made using discrete components and hybrid micro circuits. There have been obsolescence issues with the hybrid micro circuits. The board provides 5 output voltages, viz. +5V DC, +15V DC and +24V DC. While +5V DC is used for the digital circuits, +15V DC is used for the analog circuits and +24V DC is essentially used for powering the voltage and current sensors of LEM make and relays. In the functionally equivalent card, use of power bricks/modules from reputed suppliers like Vicor, TDK Lambda, Cosel, Recom etc. of different voltage and power level with suitable cooling and protection also provided.

IGBT Speed Sensor

The Hall effect active speed sensor is powered by the power supply from the IGBT based traction converter control electronics (8 to 32 VDC) and output pulse amplitude shall be maintained strong under very adverse conditions like ingress of grease, increse of air gap, misalignment of motor shaft etc. This hall effect active speed sensor can sense the speed close to zero speed sensor measures the speed on the hall effect sensing principle and provides very accurate measurement almost till zero speed.The sensor shall be embedded in housing along with its electronics circuitry for pulse amplification and power circuit and signal conditioning. A tooth wheel having 120 teeth shall be attached to the motor shaft. The output pulses shall be open collector type so that it can be fed directly into the IGBT based traction converter electronics.

N2 POWER SUPPLY BOARD

N2 board is designed and manufactured by Traintech Electronics Pvt ltd , Bangalore for use in the Faiveley based Wheel slide protection (WSP) system. The N2 board is totally equivalent to the Faiveley N2 board and can directly replace it. The N2 power supply is a sub-assembly of the WSP system. This provides the required 5V and 15V power supply to the WPS control boards, when inserted into the assigned slot of the WPS Rack system. The N2 Power Supply has a 25-pin sub-D connector through which input power is applied to it. The outputs and various ON/ OFF control inputs are provided at the rear side Back Plane connector.

AS-PERI CARD(XV A987)

The Diagnostic Terminal fault indication is a robust terminal device constructed for harsh environments. A special wide temperature electronic ,a wide temperature LCD (4*40 characters, LED backlight) and switch panel {max 32 keys} with EMI protection are used to meet the EN50155 and the IEC 801-x specification.

Distributed Power Wireless Control System

Distributed Power Wireless Control System (DPWCS) used in 3-Phase Electric Locomotives [of WAG9, WAG9H, WAP7 & WAP5 classes] being operated by Indian Railways. The DPWCS System is designed to increase the throughput of the railway line tremendously without much additional input. DPWCS operation enables heavy haul with minimum coupler forces. Under DPWCS scheme, locomotives are distributed at different points in a long train and controlled through wireless from the master, and slave locomotive crew can be eliminated, if desired.

DPWCS complete system consists:

Control & Communication Unit (CCU)
Brake Interface Unit (BIU)
Driver Interface unit (DIU)
Pressure Sensor Unit (PSU)

1. Control & Communication Unit (CCU)

Control & Communication Unit is the heart of DPWCS. It takes all the commands and status information from Loco-Pilot (LP), Driver Interface Unit (DIU), Brake Interface Unit (BIU) and LOCO through MVB and 485 communication. It processes on the inputs data and transmit/receives depending on the operating modes (MASTER/SLAVE/MAIN/STANDBY).

2. Brake Interface Unit (BIU)

Brake Interface Unit is the unit that takes the Brake and pressure value as input in master mode and injects the master brake value in slave mode. There are two processor modules in the BIU viz. BRAKE MAIN and BRAKE SENTINAL. BRAKE_MAIN does all the controlling function where as the BRAKE SENTINAL monitors the brake status.

3. Driver Interface unit (DIU)

DIU is an interface between the driver and DPWCS. The DIU acts as terminal, simply to receive and display information from CCU (Control & Communication Unit) and send driver input to CCU. DIU has 1024 x 768 resolution capacitive touchscreen along with keypad support for redundancy. It supports ESD/EMD MVB or serial 485 Communication.
