Product Description:

The MMC-SDN-7.2-460-D is a standalone smart drive produced by Kollmorgen within the MMC Standalone Smart Drives series. Acting as an integrated controller and inverter, the unit accepts factory mains power and generates regulated three-phase output for positioning or speed loops, allowing machine builders to run servo or induction motors without an external motion rack. In industrial automation, it coordinates torque delivery, acceleration, and deceleration so conveyors, gantries, and feeders can operate with repeatable accuracy.

On the electrical input side, the drive draws an apparent power of 7.65 kVA from a three-phase mains supply. At rated load, this demand corresponds to 12 A RMS on each line when the plant is wired for 480 VAC. The unit is designed for 3 incoming phases, which suits typical factory power feeds. During power-up, the rectifier section experiences a surge limited to 10 A, helping keep upstream breakers within their normal operating range. On the motor side, the inverter can deliver a cyclic crest of 17 A, while its continuous armature channel supports 12 A RMS. These values set the thermal operating point of the connected motor windings and help determine appropriate conductor sizing.

Continuous motor power available at 480 VAC reaches 5 kW, while short-term overloads can be handled up to 12.5 kW without exceeding semiconductor limits. Internal dissipation is held to 153 W, which helps limit added heat inside the enclosure. The device can also reach 42.5 A peak current during brief demand spikes. Housing dimensions are 70 mm wide, 188 mm deep, and 256 mm high, enabling dense installation on DIN rails or backplates. With a mass of 2.7 kg, the unit remains manageable during installation, and the aluminum chassis channels airflow to keep junction temperatures within acceptable limits.
