Overview
The Dart Controls 253G-200C is an economical, single-phase DC motor speed controller designed for industrial automation and motion control applications. Rated for motors from 1/8 to 2.0 horsepower, this open-chassis unit provides dual voltage input (120/240 VAC) and delivers a 0–180 VDC output with wide speed adjustment capability. The 253G-200C is part of the Dart Controls 250 Series, recognized for reliability and versatility in variable-speed DC motor applications.
Key Features
- Dual voltage input (120/240 VAC, 50/60 Hz) allows flexibility in power supply configuration
- Adjustable horsepower settings (1/50 through 1/8 and 1/8 through 2 HP) accommodate various motor ratings
- Fully rated to 2 HP with no auxiliary heat sink required—integrated thermal protection
- Packaged power bridge and barrier terminal strip for simplified installation and maintenance
- Speed control potentiometer with knob and dial plate included
- Current limit trim potentiometer eliminates the need for plug-in resistors
- Suitable for open-chassis or NEMA 4/12 enclosure mounting
