4. Control functions of F/R, enable, speed reference and output functions of speed pulse(PG), alarm. Over temperature protection.

5. Three kinds of reference inputs: analog voltage, PWM, Frequency.

6. Suitable for 3-phase BLDC motors with hall sensors.

7. Use of industrial grade chips.

Model and Specification:

N series 2-Quadrant BLDC Motor Speed Driver:

Driver Numbering Information:

BLSD 12 10 DC -2Q-N-T 

BLSD:       BLDC Speed Driver

      12:       Rated Voltage(VDC)

      10:       Peak Current Limit(A)

     DC:       DC Power supply

     2Q:       2-Quadrant Driving Mode

       N:       N series(normal size and variable parameters)

      T :      -40~+65℃ Ta, Unlabelled=-10~+45℃ Ta

Notice:

1.Select peak current of driver: Ip(A)≧2*Ir(A) or Ip(A)≧4*Pom/(1.414*Vp), Irm=rated current of motor(A) Pom=Rated output power                                                      of motor(W), Vp=AC supply voltage of Driver(Vrms)

2. Driving quadrant: The drivers are only used in I&III quadrant.

3. Interference from leads: The Hall signals can be disturbed by switched current in windings leads when length is more than 3m. Don't                                                         intertwine them together. It is better to use shielded leads.

4. Motor Insultaion:  Hall sensors to Windings/Hall sensors to Motor Cse/Windings to Motor Case

                                   Insulation Resistance＞100MOhm@1500VDC

                                   Dielectric strength＜1mA@1200VAC/50-60Hz/1 minute

5.Safety:       The PE terminal labeled on the driver must be connected to the protection earth point of the supply system.
