TMEIC ARND-3110J DSP Main Control

Product Description

ARND-3110J is a core DSP main computing control board manufactured by TMEIC Japan, belonging to TMdrive-MVe2 medium voltage high-power inverter dedicated controller series.

It is specially matched with TMdrive large medium voltage frequency converters, receiving analog sampling signals and upper system operation commands from DCS/SIS, realizing vector 

closed-loop speed and torque regulation of high-voltage motors, PWM drive pulse output for power modules, and full-set electrical fault protection logic execution. The board collects voltage, 

current and temperature feedback signals, outputs isolated dry contact switch signals for interlock control of bypass cabinets, cooling fans and contactors, completes overload, overvoltage, 

overcurrent, overheating and IGBT fault protection functions.

Adopts rack slot plug-in structure, front panel LED running and fault status indicators, PCB with three-proof conformal coating, standard internal cabinet subrack installation. It is a key 

vulnerable spare part for thermal power plant boiler fans, circulating water pumps, steel mill rolling main drives, mine belt conveyor medium voltage drive equipment.
