3 The DX Power Module
The DX Power Module converts the speed and direction signals generated by a DX Remote
into high current outputs. These outputs drive the motors and activate the parkbrakes.
The Power Module must be connected to:
• The DX BUS
• The battery
• The motors
• The parkbrakes
The Power Module is fully programmable for a wide range of powerchair types and user
needs.
3.1 Available Power Modules
Power Module Current Motor type
DX-PMB
60A dual 24V DC
DX-PMB2
80A dual 24V DC
DX-PMB-S
120A single (2x 60A parallel) 24V DC
DX-PMB2-S
160A single (2x 80A parallel) 24V DC
The PMB-S has its two motor and Park Brake channels driven in parallel, for a single motor
output with twice the current of each channel of a standard Power Module. The PMB-S is
used in DX Systems with only one drive motor, such as servo steered powerchair systems.
