NW-GC-500 Revised Generator Control

and Power Selection System with HEP Feed Option

At right is a photograph of the controls of our newly revised NW-GC-500. The NW-GC-500 is a series of generator control systems for passenger car electrical lockers that is designed to allow for selection between accepting power from the HEP trainline, the on-car generator, or yard power on certain models. Additional model variations allow for yard power at either 480 volts, 240 volts, or 220 volts. Automatic controls allow for the generator to start and power the car electrical system automatically in the event that the HEP power fails. If yard power is an option, then the generator control will also automatically operate the generator if the yard power fails. The HEP feed setting of certain models of the NW-GC500 series checks the trainline for control loop completion and if no problems are found will allow the on-car generator to feed the HEP trainline.

An Adobe Acrobat version of the brochure for this product is also available in our PDF Files area. However, the new revision of the system is not featured on the brochure.

Our newly revised version features a new electronic control that integrates engine meters into the engine control unit. This significantly reduces the size of the control panel, and allows for mounting in cramped electrical lockers.

The new engine control also allows for easier programming, so that it is easier to tune the engine control to suit the particular generator controlled by the unit.

The Old Style NW-GC500 is Stil Available!

It is still possible for us to make older style NW-GC-500 series generator controls. However, we feel that many of our customers will appreciate some of the features allowed by the new engine control system:

An alternative system is the GC-135 series of generator controls, which does not have any of the automatic power transfer features of the GC-500. Instead, it is designed to provide power to the HEP power system. It is used in power cars and other cases where only a HEP feed package is desired.
