Graham Motors and Controls is offering the TECO / Westinghouse lines of AC Drives and Motors.

The Vari Speed® R400 is a full-wave DC regenerative control that provides high performance four quadrant speed and torque control. The R400 solid state controller converts single phase AC line power into an adjustable DC power to control 1/4 to 2 horsepower DC motors.

The Vari Speed¬ A2000 is compact, rugged, reliable and flexible. Available in 1/2 - 3 HP control rating configurations, the Vari Speed A2000 series incorporates surface mount technology to reduce package size and improve reliability.

The Vari Speed¬ S1000 is a high-performance DC motor speed control designed for maximum reliability in 1/20 to 2 HP applications. The surface mount technology incorporated into the design reduces package size and improves reliability.

Graham's Cycletrol¬ Series DC adjustable speed controls provide rapid cycling capabilities, while offering higher reliability and lower maintenance compared to clutch/brake mechanisms.

Rated for 1/8 to 1 HP. One piece construction - motor, controller and operator controls all assembled as one easy to install unit. On/Off switch, speed potentiometer and line fuse mounted on operator's control panel.

Designed for multi-control, master/follower speed control applications for standard permanent magnet or wound-field DC motors.

The 900 Series NEMA 4 is a high-performance DC motor speed control designed for maximum reliability in 1/20 to 1.5 HP applications. The surface mount technology incorporated into the design reduces package size and improves reliability.

A new circuit design concept combines the performance and reliability of high priced controls with the basic control functions that meet the requirements of most application.

Operates standard 90 or 180 VDC SCR rated permanent magnet motors or higher output 120 or 240 VDC PWM-rated motors.

Operates standard 90 or 180 VDC SCR rated permanent magnet motors or higher output 120 or 240 VDC PWM-rated motors.

A new circuit design concept combines the performance and reliability of high priced controls with the basic control functions the meet the requirements of most applications.

Programmable to operate as a speed or torque control. Rated for 1/8 to 3 HP.

The Universal Signal Isolator is a fully stand-alone circuit board used to pass precise analog signals between isolated input and output stages with degradation.

The MOC-1 monitors motor load and provides a latched "alarm" contact if an overload occurs. An adjustable time delay allows the MOC-1 to ignore normal acceleration currents without nuisance tripping.

The Bi-Directional Option adds rapid and reliable reversing to Graham's DC Adjustable Speed Controls. Unique control circuitry is combined with a magnetically latching relay to provide rapid motor reversal with a single quadrant drive.

Graham's permanent magnet DC motors are optimized for rapid cycling use with Cycletrol Series DC controls, All motors are in stock for prompt delivery.

600 PMDC

Designed to easily withstand high-pressure washdown's, high humidity and other harsh environments found in agriculture, marine, transportation and food processing applications.

137 Series is designed for heavier industrial applications.
