EM-347 Electromen OY DC Motor Controller, 11 → 42 V dc, 40 A, 42 V dc

Electromen - EM-347 BLDC MOTOR CONTROLLER, 12-35 V DC, 40 A_x000D_ The EM-347 is brushless DC-motor drive for motors with hall sensor feedback._x000D_ The drive has a MOSFET power stage which provides high efficiency and emits very low RF noise making is suitable for sensitive environments_x000D_ The driver can be used with 120° commutation. This driver has true 4Q power stage, and it makes possible to use regenerative braking._x000D_ In this braking method the supply voltage rises, this voltage rising can be controlled with braking resistor._x000D_ If uses battery supply then the braking energy can be leaded back to battery and braking resistor will not needed._x000D_ The unit accepts digital and analogue (0-5V or 0-10V) command inputs to control speed and direction, analogue providing proportional control if required_x000D_ EM-347 has two NPN outputs for fault and overcurrent indication use. Some input and output functions can be modified with parameters._x000D_ Driver includes overvoltage, undervoltage and overtemperature protection and an on board LED can indicate status and fault conditions_x000D_ There are open and closed loop modes - open loop (direct control) sets the motor voltage proportional to the control voltage and closed loop mode uses hall sensor feedback for more accurate speed control_x000D_ Start and stop ramp settings are available in both these modes as well as parameters to control speed range, closed loop rpm range_x000D_ The analogue input is filtered to allow it to accept a PWM signal direct to control speed directly from a PLC_x000D_ Device has also output for a cooling fan option if needed, this is switched on when temperature rises over deg 65C_x000D_ For parameter setting there is 3 options: EM-236 interface unit, EM-268 with Menthol-Lite PC-program and EM-326 with Menthol-App application for smartphone_x000D_ Features and Benefits_x000D_ Three phase output_x000D_ Speed and torque control_x000D_ Open/closed loop modes_x000D_ Regenerative braking with braking resistor output_x000D_ Current limit and trip settings_x000D_ Symmetrical control (rev-stop-fwd) option_x000D_ Fault and overcurrent outputs_x000D_ Control output for cooling fan*_x000D_ Highly efficient with very low EMC emissions_x000D_ DIN rail mountable_x000D_ Max 40A continuous @ 2kHz PWM, 30A momentary (Ta<50°C)_x000D_ * with cooling fan - max current 50A continuous_x000D_ 12-48Vdc, *30-40A continuous, 80-100A peak_x000D_ Open & closed loop control operation with hall sensor feedback_x000D_ Speed, direction, current limiting, soft start/stop and regenerative braking control_x000D_ Compact and DIN rail mountable_x000D_ Symmetrical control (rev-stop-fwd) can be achieved with EM-A1 card option_x000D_ To the motors with HALL sensors_x000D_ Three phase output_x000D_ Speed and torgue adjustment_x000D_ Open/closed loop modes_x000D_ Dynamic braking_x000D_ Control output for cooling fan._x000D_ True 4Q-power stage_x000D_ Braking resistor output_x000D_ Selectable brake mode_x000D_ Current limit and trip_x000D_ Symmetrical control option ±5V or ±10V_x000D_ Fault and overcurrent outputs_x000D_ Good efficiency_x000D_ Low EMC emissions_x000D_ DIN-rail mountable_x000D_ Rpm-pulse output option
