MDB778WP-CAN

21mm, Brushless, Low Profile, High Voltage, High Torque, Steel Gear Actuator (7.4V)  

The MDB778WP-CAN is a 21mm low-profile brushless servo actuator engineered for high-performance UAV, drone, and industrial applications where compactness, reliability, and digital protocol support are non-negotiable. Featuring a brushless motor, magnetic rotary encoder, dual ball bearings, and hardened steel gears, the MDB778WP-CAN delivers precision motion control with minimal electrical noise and maximum longevity compared to traditional cored servo designs.

With an IP-67 waterproof and dustproof rating, the MDB778WP-CAN operates reliably in demanding field environments — including aerial, marine, and industrial installations subject to moisture, dust, and contamination. Operating at 4.0–8.4V and delivering 3.2 kgf·cm torque at 7.4V via CAN 2.0A/B and DroneCAN (UAVCAN v0.0) protocols, the MDB778WP-CAN integrates seamlessly into modern UAS architectures and autonomous systems requiring reliable digital actuation.

The CAN bus interface enables multi-servo daisy-chaining, real-time telemetry feedback, and precise control in complex multi-actuator systems — making the MDB778WP-CAN a trusted solution for defense contractors, drone manufacturers, and UAS system integrators navigating NDAA supply chain compliance requirements.

Fully programmable via the DPC-20 or DPC-CAN programmer, parameters including end points, fail-safe, dead band, soft start, and overload protection can be customized for any installation. Backed by Hitec's ISO 9001:2015 certification and 50+ years of servo engineering expertise.

IMPORTANT INFORMATION > DPC-20 PROGRAMMER 
  • Hardware Type: PC USB-C to 3-pin (PWM/TTL) and 4-pin (RS485/CAN) interface.
  • Capable of configuring and testing HITEC digital servo actuators.
  • Compatible with various control methods (PWM, RS485, CAN), offering a seamless transition from legacy DPC-11, DPC-485, and DPC-CAN units.
  • Different servo actuator series require dedicated UI programs due to variations in communication protocols.
  • Ensure you connect the appropriate power supply to the DPC-20 for the connected servo actuator.
  • For servo actuators (5/7 Series, 9 Series, D/MD Series), connect to the 3-pin port on the DPC-20, and connect the power supply to the BAT- and BAT+ pins on the 4-pin port, paying careful attention to polarity.
  • DPC-20 Wiring Diagrams are located on the DPC-20 UI HUB DOCUMENTATION.
