DHMCU DHPS380 Intelligent Servo Driver Board (12V-24V Replacement / Spare)

The DHMCU DHPS380 Intelligent Driver Board is the official factory replacement controller PCB for both 200kg.cm and 400kg.cm DHPS380 series high-torque digital servos. Featuring integrated 12-bit magnetic angle encoding, robust MOSFET H-bridge driver stage, and dual hardware adjustment potentiometers, this board allows field repair, replacement, or custom integration.

Key Features & Technical Specifications

• Operating Voltage: DC 12V – 24V (supports up to 30V max).
• Current Rating & Protection: Built-in 5A hardware overcurrent protection clamping and reverse-polarity protection.
• Position Sensing: High-precision 12-bit contactless magnetic rotary encoder interface (0.087° resolution, immune to dust and vibration).
• Hardware Trimmers (On-Board Tuning):
  • M Key & Trim Potentiometer: Direct neutral center/median position alignment with non-volatile EEPROM storage.
  • A Potentiometer: Adjustable travel stroke from standard angles up to 360° continuous rotation.
• Signal Modes: Standard PWM (3.3V–5.0V logic, 50–333Hz). Switchable between 0.5–2.5ms (360°) and 1.0–2.0ms standard RC mode via 1MS solder jumper.
• Direction Reversal: Solder bridge ZF pad to instantly invert CW / CCW rotation direction.
• Weight: 50 g.
