Applications

• Industrial Automation: Precise frequency conversion control for VFDs (Variable Frequency Drives).
• Motor Control: Manual speed governing for DC motor PWM controllers.
• Testing Rigs: Adjustable voltage/current references in DIY power supply builds.
• Audio Equipment: High-visibility volume or gain control for rack-mounted systems.

Project Evolution

• Past Projects (Prerequisites): If you have used standard 10K breadboard potentiometers or simple analog panel meters, the SD003 is your next logical step.
• Feature Upgrade: This product upgrades your project from "analog guesswork" to "digital precision." It eliminates the need to code an Arduino to read a pot and output to an I2C display—this unit handles the sensing and display autonomously.
• Effort Level: Beginner-Friendly. Simply provide power and connect the signal pins to your motor controller or VFD. No programming required.

Package Includes:

• 1 x Promax SD003 10K Digital Display Potentiometer
  

Frequently Asked Questions (FAQ)

• What is the resistance value of the Promax SD003?
  It has a total resistance of 10K Ohms.
• Can the display show values other than 0-100?
  Yes, the multiplier and decimal point can be adjusted in the internal settings menu.
• Does it require a separate power supply for the LED?
  Yes, the LED display requires 6-30V DC to operate.
• Is the output signal digital or analog?
  The display is digital, but the potentiometer output is a standard analog resistance change.
• Can I use this with a 5V power supply?
  No, the minimum operating voltage for the display logic is 6V DC.
• What is the panel cutout size needed?
  The required cutout is 75mm x 39.5mm.
• Is this potentiometer linear or logarithmic?
  It is a linear (Type A) potentiometer suitable for control applications.
• Can I use this for AC dimming?
  No, this is rated for DC control signals only.
• How do I change the magnification settings?
  Long-press the adjustment button (if equipped) or follow the datasheet for the internal jumper/menu settings.
• Does it remember settings after power off?
  Yes, display range and decimal settings are saved in non-volatile memory.
• Is it waterproof?
  No, it is an industrial panel-mount unit intended for indoor or enclosure use.
• What connectors does it use?
  It uses a combination of screw terminals for power and JST connectors for signal.
• Can it handle high wattage?
  No, it is intended for signal-level control (typically <0.5W).
• What color is the LED display?
  The display features high-contrast Red LEDs.
• Can I reverse the display (100-0 instead of 0-100)?
  Yes, by swapping the outer pins of the potentiometer signal cable.
• Is the knob removable?
  Yes, the knob can be replaced with any standard 6mm D-shaft knob.
• What is the accuracy of the display?
  The display has a typical accuracy of ±1%.
• Can I connect this directly to an ESP32?
  Yes, as long as the pot signal is within the ESP32's ADC limits (3.3V).
• Does it come with the JST cable?
  Yes, the package typically includes the necessary wiring harness.
• Is this suitable for 24V industrial systems?
  Perfectly. It supports up to 30V DC, making it ideal for 24V PLC or VFD systems.
