Minarik Drives introduces MDBL Series of configurable controls for brushless DC motors

January 17, 2019 – Minarik Drives has introduced the MDBL Series, a family of configurable controls for brushless DC motors. MDBL drives control motors ranging from 90 to 280 VDC, up to 5 amps/1.5 HP, using either 115 VAC or 230 VAC line sources. On-board trim pots allow operators to set minimum/maximum speeds, acceleration/deceleration rates, motoring and regening current limits, as well as the proportional and integral feedback gains.

An onboard microprocessor allows for custom programming the MDBL Series – for tasks as simple as changing the purpose of a jumper or trim pot, or as complex as programming an entire application-specific routine. The MDBL also integrates PLC-like functionality into operations, eliminating the need for a separate PLC altogether or enhancing systems without PLCs. These controls are positioning-application capable, with feedback sampling rates of 16Khz. Each drive is designed for feedback from 120° hall effect sensors and can be commanded with a range of analog inputs with Minarik Drives’ built-in isolation.

Minarik MDBL Series Highlights: • UL 61800-5-1 listed (NOTE: this standard will obsolete UL 508C in 2020) • NEMA 4X packages available in both steel and plastic • Doubler mode: Able to convert 115 VAC input into 280 VDC output. • Isolated inputs: Accepts floating or grounded signals 0 ± 5 VDC, 0 ± 10 VDC or 4-20 mA • Diagnostic LEDs for power and status (e.g. undervoltage, overvoltage, short circuit/current trip, overheating warning/trip) • Thermally-protected – recognizes when overheated as a result of overload • Hall effect sensors: 120°, 5 VDC, 75 mA combined • SEPARATE current limits for operation and regen braking • 16-bit microcontroller on board, ready for mission-specific configurations
