ACBT
The ACBT (Auto Traditional Track Circuit) is a device designed to safely power and manage single-escape track circuits.
It supplies 50 Hz or 83.3 Hz current with PSK modulation, distributing controlled power to minimise the need for frequent calibrations.
It features LED indicators and a test button for immediate on-site control, reducing intervention times. Thanks to its compact architecture and limited power output, it ensures safety and operational stability in all conditions.
- Operating frequencies: 50 Hz / 83.3 Hz
- Minimum guaranteed shunt: > 0.8Ω
- TC length: 36 m to 700 m
- Signals: Front LEDs and test button
- Dimensions: 150 × 100 × 300 mm
- Power output: < 40 J
ACBT cabinet
The ACBT cabinet is a compact, modular solution designed to house and manage up to 12 ACBT devices within a single structure.
Designed to simplify installation and optimise space, the cabinet integrates the necessary cabling, protection systems and a fan drawer for cooling and diagnostics.
