The MRServo-3HV is a variant of our popular MRServo-3 switch machines that can handle a wider range of supply voltages (8VDC up to 26VDC) with high efficiency.  We've replaced the standard 7805 linear regulator in the design with an economical switching power supply module to provide high efficiency power conversion.

Dimensions

1.7"(L) x 1.2"(W) x 0.9"(H)

Customization

Need a slower or longer throw than the conventional MRServo design offers? We are able to customize the MRServo software to some extent and can provide custom-programmed units for a small fee. Email us and let us know your requirements, and we will be in touch about what we can do.

Instruction Manual
Schematic

The latest MRServo hardware design files and source code are now available at GitHub!

Note:  The MRServo HV versions substitute a Recom R78-E-5.0-0.5 regulator for the 7805 in the schematic, allowing for up to 28VDC power supplies.

Typical Quiescent Current @ VDD=12V, servo not moving:

50mA (CNTL = GND)
2mA (CNTL = 12V or Floating)
