Home > Analog SCR Drives > 253G 2HP NEMA DC Speed Control

The 250 Series offers superb flexibility, reliability, and value. A general purpose, economical control rated to 2 horsepower, it provides the ultimate in standard features and versatility including: dual voltage (120/240VAC), adjustable H.P. settings, packaged power bridge, barrier terminal strip, fully rated-no auxiliary heatsink required, and chassis or NEMA 4/12 enclosure. Many options further extend the 250’s capabilities. A logical, easily accessible layout simplifies installation and adjustment. Clean design, quality components and careful assembly are trademarks of Dart Controls.
