Product Description:

The MMC-SD-3.0-230-D smart drive is a standalone servo amplifier manufactured by Kollmorgen and assigned to the MMC Standalone Smart Drives series. It converts three-phase 230 V mains into a controlled, low-ripple output for servo or induction motors used in conveyors, indexers, and packaging stations. A built-in DC bus, relay contacts, and control logic allow the module to handle axis power, braking, and I/O tasks without external components, which helps simplify panel layouts in industrial automation.

The drive can supply a continuous motor phase current of 10.6 A RMS, which is the heat-limited load it can support continuously. For brief accelerations, it delivers up to 30 A peak, which sets the maximum torque available during rapid starts or directional changes. Incoming power requirements reach 3.0 kVA on a balanced three-phase line, so the feeder circuit and protection devices must be sized accordingly. Internal protection opens the DC bus if its voltage rises beyond 420 VDC, which helps prevent semiconductor damage during regenerative events. Energy is smoothed by a bus capacitance of 1880 µF, which lowers ripple and stores charge for transient current demands.

A nominal mains draw of 14 A RMS reflects typical running conditions, while startup is limited by an inrush peak of 70 A peak, which guides the selection of line contactors and fusing. The power stage can continuously export 3 kW to the motor yet dissipates only 90 W as heat, indicating high conversion efficiency and modest cooling needs. The housing measures 246.13 mm in height, 119.05 mm in width, and 155.56 mm in depth, allowing installation in shallow enclosures. The aluminum chassis weighs 2.59 kg and carries a form-C relay rated for 24 VDC control at 831 VA switching power, enabling direct interfacing with brakes or contactors.
