MAB Robotics
Power distribution system
The system, dedicated to mobile robotics, allows for managing the distribution of power between components. CANdle ecosystem compatibility provides support for other MAB products series, and stackable, modular architecture makes it easy to scale and customize your projects. The PDS accurately monitors the current, voltage and temperature of connected devices and the RGB power button helps you to recognize whether the board is on or off.

Scalability
The PDS addresses all challenges of power distribution in mobile robotics. Key components of the system are:
-
the control board - the board which manages and acquires data from the other modules and communicates over CAN-FD. It also handles RGB switch and safety inputs, so the whole system can be directly used as a turn-key solution - onboard electronics for any robot.
-
the power stage - a standalone module that handles power delivery to the load, like motor controllers. A single module can handle current up to 50A. It is equipped with isolated voltage and current sensors to monitor power consumption safely. Additionally, on the board, there are high-quality, low-ESR capacitors, which can store regenerative power, decreasing risk of the overvoltages and increasing system efficiency.
-
the isolated DC/DC converter - a module with a reliable power supply for internal robots modules, like computers or sensors, for which galvanic isolation and protection mechanisms are crucial. They are frequently expensive and require a stable power supply, decoupled from, for example, the motors bus to avoid problems during overloads or failures.
-
the brake resistor - it is a complementary subsystem with the power stage module. In systems supplied from bench supplies, and sometimes even in battery-powered systems, regenerative braking can cause destructive overvoltage. The use of a braking resistor protects against such events. The PDS provides high-power, low-profile, and reliable modules which solve this problem seamlessly.
All modules are fully protected against reverse polarity. Modules can be mixed in various configurations, up to 6 per system. After reaching that limit, it is possible to connect multiple systems to one CAN-FD line. To make it easy to integrate the PDS in robots, we provide bus bars dedicated to specific applications.
The system can also be customized to your project for request. Tell us how we can help!
