power distribution module: functionality & power

The POWERPAC High-Power Distribution Module simplifies hybrid and electric vehicle design by protecting all of the high-power hybrid components from power spikes and surges. The Power Distribution Module, also known as a Junction Box and Induction Controller, routes power from the High-Voltage Hybrid Battery to the Traction Inverter, DC-DC Converter, DC-AC Inverter, and other hybrid components.


The high-voltage fuses protect valuable components against inadvertent power surges and are easily replaced by the operator or mechanics. When the user-access panel is opened, the Safety Switch isolates the power from the fuses and circuits in the Power Distribution Module, protecting the operator or mechanic from the electrical power.



The chassis is sealed to IP67 / 6K9K and can be customized by Curtiss-Wright engineers with various connectors based on Vehicle OEM design requirements.



The POWERPAC series is purpose-built for on-highway and off-highway applications. The POWERPAC Hybrid Vehicle Component Series has over 500 million vehicle miles of on-road service in punishing municipal bus and service truck applications, delivering proven technology in the field and on the road.

FAQ: Induction Motor Controllers

What are the types of motor controls?

There are four main motor controller and drive types: 

  • AC
  • DC
  • Servo
  • Stepper

What is a DC controller?

A DC (direct current) controller is a type of electric device that transforms electrical energy into mechanical energy. 


What is the difference between a motor driver and a motor controller?

A motor driver and a motor controller have one main difference:

  • A motor controller is responsible for controlling the speed, torque, and the direction of the motor.
  • A motor driver is responsible for providing enough electrical power to the motor as per requirement.
