The MC018 high-current controller was released by Danfoss as part of the PLUS+1Ò microcontroller family. The equipment is designed to solve challenges customers face with controlling high-current devices, such as excessive noise, moderate pin/controller power, and lack of intelligent capabilities.
Innovative features enable customers to lower overall system and maintenance costs while boosting the efficiency of their machines. The MC018 High-Current Controller is rated to maximum total current of 160 A and steady state current of 120 A. This higher maximum current allows more devices to be simultaneously powered by one controller, reducing the number of controllers needed and thereby reducing the total cost of the system.
At maximum load, MC018 can run up to 4kHz and up to 20kHz at a reduced load. The higher frequency makes

Control is also improved with the programmability of MC018. As part of the PLUS+1 line of microcontrollers, MC018 is already compliant with the PLUS+1 platform. The pre-engineered function blocks in PLUS+1 give OEMs the opportunity to program functions that would otherwise require extra time or components, or may not have been feasible at all. One of these features includes the “soft fuse” — a programmable fuse that can be set to switch when the current is above a certain value — which provides enhanced safety performance.
An additional safety feature is the separate power supply for the logic circuit. The separate power input keeps the controller running even when outputs have short-circuited, meaning it can continue to provide insights to the master controller. This reduces time in diagnostics and repair and could reduce warranty costs.
The unit is suitable for actuators, windshield wipers, fan drive, lamps, lights, engine starter, and leveling control applications.
