Traction Power Rectifier Units

Train rectifier units are responsible for AC and DC power conversion. These items are common to find on light rail, transit system applications and on subways. CP traction power rectifiers are responsible for a natural convection assembly that prevents overloads and manages power within the train.

Most transit system applications work within air-cooled power silicon assembly. A series of silicon diodes are installed and tested to be field-proven for years of use. These diodes are directly responsible for preventing overload capabilities.

Most traction power rectifier units are responsible for delivering 12 pulses direct current or six pulses direct current. Depending on the power ratings of the Traynor vehicle that they are installed on, the device will be responsible for managing a full load of up to 1500 V DC at 100% capacity. Most of the power ratings on these devices range up to 5000 kW and there are heavy-duty units available to handle specialty vehicles.

Standard features include surge protection, door interlock support, the current balance in, diode fuse monitors and diode fuse replacements. Optional features can also be included on these devices including custom cabinet lights, DC Ammeter, annunciator, DC voltmeter, and a structure ground relay device for enhanced monitoring.

A traction rectifier unit needs to be built with quality to monitor power conversion tasks and to ensure that the quality of the power within the train can be verified. With a wealth of additional features that can be added into these units as well as standard features that are responsible for managing power tasks in a wide range of vehicles, these are systems that can be crucial to operating subways, trains and more.
