Features

• The latest product HQ-SXPWM-X (ultra-wide voltage AC90V-AC260V) input high-power DC motor governor using pulse width modulation technology, selection of today's advanced switching device design and production, with a small size, no noise, high efficiency. And has advanced short circuit, over-current, over-temperature protection, and the armature voltage stability of the output voltage, the armature voltage from zero to rated continuously adjustable,which makes the motor speed is very convenient.
• As a result of high frequency, so as to ensure that the motor at low speed to stabilize the work (that is, there is no crawling phenomenon), is an ideal alternative to SCR power supply products. Widely used in wire, cable, light industry, textile, paper, chemical, printing and dyeing, metallurgy, rubber, drawing, extrusion machinery, medical equipment, food production, printing and packaging industries, small DC motor armature, DC motor to achieve constant torque stepless speed regulation.
• Features :
  1, the use of pulse width technology to make the speed more stable, low-speed efforts
  2, with short circuit, over current, over-temperature protection cut-off device to make the performance more reliable
  3, with soft-start device to eliminate the motor starting current is too large
  4, high and low voltage signal completely isolated, the use of more secure
  
• Attention :
  1, the governor to close the input power, the hands of a minute to prohibit high-pressure touch terminals, there are high-voltage capacitors to prevent electric shock!
  2, for the two lines of the DC permanent magnet motor, two leads directly to the armature M + with M-. Prohibited access excitation!
  
• Instructions for use :
  PWM signal requirements: the default PWM signal level is 5V, the signal frequency 1KHZ above, with a load capacity of more than 0.5MA. 2,5V level without string resistance Input at PWM port, 10V level PWM input from 0-10V port or string 10K resistor at PWM port input, 12V level string 3.9K resistor from 0-10V port input or string 13.7K resistor In the PWM port input, 24V level string 16.8K resistor from 0-10V port input or string 27K resistor in the PWM port input
