DIN rail type AC-DC power supply for railways
High-performance DIN rail power supply "TDR Series" supporting stable operation of railway signal equipment with three-phase input compatibility.
In the railway industry, signal systems require extremely high reliability and stability of power supply to maintain operational safety. In particular, signal equipment is designed for long-term continuous operation, and fluctuations in voltage or unexpected troubles can have serious consequences. The TDR Series supports three-phase AC input from 340V to 550V and allows for direct power supply without the need for conversion equipment, contributing to simplified wiring and reduced design workload. It also supports two-phase input, providing a highly reliable design that supports stable operation of equipment even in the event of trouble. 【Usage Scenarios】 - Power supply for railway signal control panels - Stable power supply for signal equipment requiring high power - DIN rail installation in limited spaces 【Benefits of Implementation】 - Reduction of conversion equipment and simplification of wiring structure due to three-phase input support - Reduced risk of equipment downtime through redundancy provided by two-phase input support - Space-saving within control panels achieved through a slim design
