MDPM Series

The MDPM series is Minarik Drives’ response to the growing demand for custom drives specific to an OEM’s application. We’ve designed a microprocessor-based regenerative PWM platform that will run brushed, brushless and AC motors. The MDPM series is the DC brushed version of this platform, with the MDBL and MDVF as the compliments.

The benefit of a single platform is that it allows for quick customization with most of the changes occurring in the microprocessor’s programming. With circuit boards and components being utilized across multiple platforms, the economies of scale allow us to pass the savings on to you.

The MDPM contains a unique feature to the DC brushed world: the “doubler mode”, something only found in the AC world. It can operate in three power modes: 115 in – 130 out; 230 in – 240 out; 115 in – 230 out. The configuration is done through making the AC line connections to different terminals on the drive, eliminating the need for switches and jumpers. PWM drives are also preferred over SCR drives when running a 90/130 VDC motor off a 230 VAC line, making this drive a one-stop solution for OEMs who manufacture for different line voltages or use a wide range of motors.

The MDPM also has the circuitry required for the hookup of an external dump resistor, eliminating the need for a separate dynamic braking module.

  • Microprocessor based: Allows custom programming for OEM’s.
  • 4Q Reversing: Regenerative/4 quadrant drives have the ability to preform quick and contractor less reversing on-the-fly.
  • Speed range, regulation, and form factor: 1% of base speed regulation with a 100:1 speed range and a 1.05 form factor over the entire range.
  • User adjustable calibration pots: Minimum Speed, Forward Maximum Speed, Revers Maximum Speed, Motor Torque, Regen Torque, IR Compensation, Forward Acceleration and Reverse Acceleration.
  • Diagnostic LED: LED for power and status (undervoltage, overvoltage, short circuit/current trip, heating warning/trip).
  • Thermally protects: Drive recognizes when overheated as a result of overload. It first flashes a warning code on the status LED and will eventually trip if the condition persists.
  • Stopping modes: User can decelerate, regeneratively brake, or coast the motor to a stop.
  • Dump circuitry: Internal circuitry for the hookup of an external dump resistor.
  • Quadrature encoder option: For OEM applications, the drive can be programmed to follow quadrature encoder feedback without any circuitry changes.
  • Auto-ranging power supply: Can accept 90-240 VAC or 80-340 VDC as an alternative to an AC input. Connection will vary.
  • RoHS: All MDPM series models are RoHS compliant.
