Power supply systems for signalling equipment, code transmitters, flashers and battery chargers.
Our modular power supply system can feed the various types of signalling loads according to their requirements. Its system design keeps the quality of the supply free from disturbances on the AC mains feeding the equipment. If the equipment or a part of it fails, interchangeable modules keep troubleshooting time short, and supply continuity and quality are maintained during replacement. The system is built from functional subsystems that can also be used on their own.
The equipment generates and monitors the coded 75 Hz supply voltages used to feed track circuits and radiating cables. In its full configuration it generates all codes used by the Hungarian railways. It continuously checks the codes sent to the track and the correctness of the coding, and regularly tests its own circuits. Its design has been proven to meet the safety requirements.
The MATÜA-01 code transmitter interrupts (codes) the 220 V / 75 Hz primary supply of 75 Hz track circuits. It replaces the earlier group of three separate units (code transmitter, code follower, power supply) that performed this task, and also meets additional requirements that could not be met with the earlier code transmitter.
The MÜA120-01 electronic code transmitter – an add-on unit for the MATÜA-01 block code transmitter – generates the 120 km/h track information (the so-called 4* code) in the 75 Hz track circuits of signalling equipment, which is needed to operate EVM-120 train stop equipment.
The MA-BL-24/16 DC flasher unit supplies the 24 V DC flashing lights in the signalling equipment of MÁV.
The SAT switched-mode battery chargers are designed for charging sealed (gel) batteries.
