The features of the NW-25200:

• As with the single zone NW-25100 system, the NW-25200 is may use a programmagle logic controller as seen in the photo immediately below or with industrial temperature controllers as seen in the following photo.
• Amtrak and transit compliant HEP Main Breaker for 480 volt power coming from the head-end power system.
• Five 480 volt, three phase circuit breaker positions (six including the HEP main breaker).
• Three-phase power monitor equipped on older units and can still be supplied of desired, but in most recent systems this has been moved to the air conditioning condenser as that is the most critical piece of equipment to protect from incorrect phase rotation.
• Forty-Two 120 volt, single phase circuit breaker positions, which may be combined into 208 volt single phase or 208 volt three phase circuits.
• HVAC Control Panels are the same as used on the NW-25100 package. This provides ease of use and conformity in appearance with single-level cars that use that Northwest Rail Electric control package.
• Control for four HVAC stages in each zone:
  • Air conditioning and heat capacity staging may be adjusted to suit the needs and system desired. For example, several stages of heat and a single stage of air conditioning. Dehumidification and separate baseboard heat control for a separate heating zone may also be added.
  • Where necessary, a short-cycle timer may be added to prevent the air conditioning compressor from starting too frequently.
  • Various configurations may be built to custom order.
  • Blower speed is reduced during heat stages to increase passenger comfort while still delivering full air conditioning capacity when needed. A single speed blower option is also available.
  • Current Temperature and Set Point Temperature Display
  • Switches and indicator lights provide easy selection of control functions and show system status.
• 24 volt control voltage circuit breaker
• Two Emergency lighting circuit breakers and relays are provided for automatic operating of emergency lighting system. There is one zone of emergency lighting for each control panel.
• Custom-made engraved plastic circuit breaker labels may be made to order for whatever electrical loads are in the car. The standard color is black text on a white background, but various other colors are possible if custom ordered ahead of time.
• 120 volt (or 480 volt as required) to 24 volt transformer supplies all low voltage electrical equipment on the NW25-200. This transformer may be either built in to the panel or come as a separate supply with a plug connector, as required by space constraints. On systems with a programmable logic controller, the power supply for the system is 24 volt DC.
• All panel covers are powder coated (not painted) to provide a high-quality, long-lasting finish.
• A hinged cover over the control components allows for hands-free access to the interior components.
