4QD Pro-160 Controller, High Current
4QD - Packed with advanced features yet simple to set up and operate, the Pro-160 delivers professional-grade motor control without the complexity. All settings can be adjusted directly from its built-in keypad and display—no programmer or PC software required—giving you all the performance and flexibility you need without a steep learning curve.
The LCD display lets you keep an eye on voltage, current, temperature, and more at a glance. Multiple input options make it easy to connect radio control, temperature and speed sensors, dead-man’s handles, and limit switches etc.
Important Note: ISP components must be fitted to each motor to protect the controller.

With its full H-bridge programmable PWM design, the Pro-160 eliminates the need for reversing relays—ensuring long-term reliability.
The standard version is ideally suited for motors up to around 2kW and the high current version up to 3kW. The standard maximum voltage is a nominal 48V, but we also have high voltage variants that can go to 84V.
Features
2 line LCD display makes this not just a controller, it’s a full information system for your installation, it can show:
Battery voltage [now with battery “fuel tank” via coulomb counting in 2.5.3 software].
Motor and battery current [you’ll be surprised how different they can be!]
Controller temperature, [+2 external temperatures with optional extra sensors] .
Throttle position.
RPM & speed [with optional speed sensor]
Can be mounted conveniently to provide information to the driver.
Built in radio control input.
Easily adjustable control over many features including:
Acceleration and deceleration.
Maximum speed.
Maximum drive current.
Regenerative braking current [variable “on the fly” in 2.3.4].
Dynamic braking in joystick mode – pull back to brake [in 2.3.3].
Low voltage alert and “limp home mode” to protect expensive lithium batteries.
Dead-mans handle input.
15 profiles for storing different configurations, 1st 9 pre-programmed for the most common applications.
A single switch to toggle between any 2 profiles e.g. RC and hand control, or fast and slow. Ideal for training new drivers.
Top speed limiting [with optional speed sensor]
Overheat warning and cut-out , also overheat warning for 2 motors with extra sensors.
12V to 84V without adjustment, * depends on version.
Peak current 200A, * depends on version and heatsink [not enough? our Pro-360 can handle 360A].
Datalogging to uSD card [needs 2.5.3 or later software].
Coulomb counting, provides an accurate measure of battery life remaining [needs 2.5.3 or later software].
Input learning feature allows:
Single ended or joystick [wig-wag] operation.
Fine tuning of pot or RC stick positions.
Voltage control.
Safety contactor driver.
Parking brake driver for vehicle applications.
Push button mode.
Other inputs:
Emergency stop.
2 x limit switches.
Speed sensor.
Software updates via uSD card
Based on a specialised Infineon microprocessor with deadtime control to prevent shoot through mosfet failures.
