    The Dual Half Bridge (DHB) is a high current amplifier which allows low current auxiliary outputs to drive high current loads such as motors. It contains two high current half bridge outputs enabling it to drive a single motor in two directions, or drive two motors in a single direction. It is also capable of high speed PWM, which can be used for speed control of motors and for other purposes.

    The DHB connects to any auxiliary output of a MoTeC ECU or Dash Logger, which performs the control function, such as PWM speed control, direction control or servo control.

    The fully sealed case makes the DHB suitable for under hood mounting.s.

    Application examples:

    • Servo motor e.g. active wing control, boat trim control, inlet runner length control, variable valve lift.

    • Motor speed control e.g. electric water pump, thermo fan, fuel pump.

    • Solenoid control.
