Product Description:
The SE2302 is a DC motor controller manufactured by Kollmorgen as part of the SE2000 DC Motor Controllers series. It modulates armature voltage to regulate speed, direction, and braking for automated conveyors, indexing tables, and similar motion axes. By bridging standard AC utility power with industrial DC motors, the unit supplies controlled acceleration and deceleration that help keep production equipment synchronized with process demands. Its operating role suits machinery that needs repeatable starts, stops, and directional changes during normal cycle operation.
Powered from a 230 VAC mains connection, the controller accepts a single-phase input and protects upstream logic through isolated control circuitry. Internal forward and reverse contactors, together with anti-plugging logic, enable rapid direction changes without contact overlap. Closed-loop regulation spans a 30:1 speed window, so low-speed setpoints can be reached without constant retuning as load conditions change. Dynamic braking hardware is built in to shorten electrical stopping time and improve control during deceleration. When short overloads occur, the power stage can sustain 150% for 1 minute before current limiting activates, helping the controller manage temporary demand spikes during acceleration or reversing.
Ambient operation is permitted up to 55 °C, and installation heights can reach 1000 m without derating. The drive is rated for continuous duty and uses the reversing-brake topology required for quick stops followed by immediate restarts. Line protection is handled by an integral circuit breaker, and the dedicated forward and reverse contactors arrive prewired to reduce external wiring complexity. When paired with a shunt-wound or PM DC motor, the isolated design supports orderly grounding and enclosure layout. The controller is housed in a chassis-style enclosure that bolts directly to a panel, which suits industrial cabinets where stable mounting and clear power routing are important.
