Product Description:
The SE2105 is a DC motor controller built by Kollmorgen and supplied within the SE2000 DC Motor Controllers series. The unit converts single-phase AC power to regulated DC armature output so that permanent-magnet or shunt motors can be speed-controlled in automated conveyors, winding stations, and similar duty cycles. By monitoring tachometer feedback, the controller maintains set speed under variable load, making it a core component in closed-loop industrial automation systems. Its chassis package mounts easily inside control cabinets alongside contactors and process I/O.
Electrically, the drive accepts a nominal line of 230 VAC and operates on a single-phase supply, with an input window of ±10% to tolerate typical facility voltage swings. A built-in two-pole circuit breaker disconnects the mains and protects downstream components, while operation is rated for continuous duty without thermal cutback. When short surges occur, the power section can deliver 150% for 1 min, allowing acceleration of high-inertia loads. Closed-loop control using a tachometer reference holds speed to within ±0.5% of the setpoint. These figures describe the electrical margin, protective capacity, and regulation precision expected when the controller is paired with correctly matched motors and line reactors.
Mechanical parameters guide cabinet layout. The aluminum chassis is 11.75 in tall, 9.5 in wide, and mounts on a back-panel plane 10.25 in above the enclosure base; mounting slots measure 0.218 in in diameter and are spaced 8.75 in apart laterally. With these clearances, airflow keeps the heat sink surface below a maximum chassis temperature of 55 °C at the specified ambient. Using tachometer feedback, the speed loop spans a ratio of 50:1, giving slow-crawl positioning as well as full-speed throughput within the same installation. The physical footprint and broad speed range support compact integration in conveyors, mixers, or machine tools where panel space and precise low-speed torque are both important.
