BLDC driver BLD‑20DIN is a device designed to control 3‑phase DC motors with Hall sensors. BLD‑20DIN controls motor speed, acceleration and deceleration, direction. The design of the driver includes internal braking resistor for recuperative energy consumption during deceleration of inertial loads. BLD‑20DIN is designed for DIN rail mounting. BLD‑20DIN has inputs for external signals (clean contact): - signal START/STOP for start and stop of the motor motion - signal DIR for control of rotation direction - alarm stop signal Speed control: - to adjust motion speed there is an internal potentiometer and inputs for connection of an external potentiometer. Analog voltage signal 0..5VDC also can be used for speed regulation.

BLSD‑20Modbus is a brushless DC motor controller for 3-phase motors with Hall sensors. This intelligent controller can be pre-programmed according to the system demands and work as a standalone drive, can operate as a slave in RS-485 network or operate as a simple DC brushless motor controller for speed control. BLSD-20Modbus provides position control based on Hall sensors information, speed regulation, current limiting function. Thanks to the current limiting function, BLSD-20Modbus protects the motor from overloads. Maximum rated current can be limited according to the brushless motor model (up to 20A). This controller is used for DC brushless motors 24V, 36V, 48V with rated power up to 1000W. BLSD-20Modbus can be used as a standalone unit or can be controlled by a master device in RS-485 network. The controller is programmable, the programming software is easy to use and free of charge.

BMD‑20DIN are speed drivers for DC brush motors. Speed, acceleration and deceleration time are adjusted by the internal potentiometers on the frame of the driver. Speed also can be adjusted by an external potentiometer or by an analog proportional signal 0 ‑ 5 VDC. Direction can be changed by external signal (clean contact) “DIR”. For safety reasons the drivers provide adjusting of a maximum continuous motor current, this function protects motors from overcurrent. There is an emergency input HARD STOP in the drivers. It is intended for mechanics protection - the motor stops immediately in case the protection circuit is broken. Adjustment of a threshold of operation of protection is carried out by a potentiometer of "Current adjust". With its help maximum permissible current for each specific engine controlled by the unit is set. The limitation current value can be set precisely. Exceeding of this current during no more than 5 sec will lead to transition to emergency operation.
