A compact, programmable DC speed control with digital closed loop feedback and LED display for DC motors rated to 2 horsepower. An on-board microprocessor with non-volatile memory, coupled with sophisticated internal software, makes Dart's Micro-Drive the ultimate value in accuracy and control. Friendly front-panel field programming permits customizing the MD for specific applications. The MD can be set to display the target speed directly in RPM, FPM, GPM, process time, or any other engineering unit. Programmable parameters include maximum and minimum set speed, decimal points, operating mode (master or follower), and the constant which takes into account motor gear ratios. The Micro-Drive is simple to operate: set the desired RPM, rate, or time in the large 1/2? LED display by depressing the "Up" and "Down" pushbuttons on the front panel. Settings can be one digit at a time or fast sweep. The Micro-Drive settings are exact and repeatable. It will precisely control speed to ±1/2 RPM of set speed, long term. No calibrations of the control are necessary. Industry standard cutout dimensions of 1/8 DIN and 1/4 DIN provide easy panel installation. All wiring connects directly to a rugged screw type terminal strip through the rear panel. The flexibility of Dart's Micro-Drive design makes it uniquely suited for many commercial and industrial applications. This series features dual voltage and adjustable horsepower drives.

The MD plus is a field-programmable closed loop DC drive system employing an advanced velocity-form PID algorithm for accurate and responsive control. The MD plus system also features a unique, isolated 4-20mA input and output for easy integration with existing Process Control systems. The MD plus system is ideally suited for metering pump applications by efficiently combining all of the application requirements into a single compact package. The MD plus system not only accepts a 4-20mA signal to control the pump speed, but it also provides a 4-20mA output signal back to the Process Control that is proportional to the actual running speed. Both the input and output signals are isolated from each other and from the control itself. The MD plus system also has two field-programmable Form C relay contacts that can be set to indicate a wide variety of conditions such as the pump is running, a "fault" condition exists, and many other events. The MD plus system is available in both enclosed and panel-mount versions. The MD50E-420 version comes in a NEMA 4X enclosure complete with an auto/off/manual switch on the cover. The 1/8 DIN MD40P-420 and 1/4 DIN MD50P-420 panel-mount versions come complete with a NEMA 4X rated faceplate, gasket kit, stainless steel mounting hardware, and connections for an external auto/manual switch. This series features dual voltage and adjustable horsepower drives.

A general purpose, economical variable speed control for small DC and universal motor applications featuring: dual input voltages of 12/24 VAC or 120/240 VAC with DC output current rating of 2 Amps, adjustable trimpot settings, and quick connect terminal pins. The 15 Series is available in two compact panel mount styles and a NEMA 4/12 enclosed model. This series features dual voltage and adjustable horsepower drives.

Rated for 10 amps continuous current, the 65E10 is a high performance PWM control for 12, 24, and 36-volt battery powered equipment.

Dart's 65 Series control is designed for heavy duty battery operated PM motors, such as: power floor scrubbers, small personnel carriers, AGV's, agricultural sprayers and a vast variety of portable equipment.

The 130 Series reversing control from Dart Controls utilizes Dart's unique zero-speed detect and solid state dynamic braking circuits. These circuits eliminate the contact arcing and failed braking problems associated with other reversing and dynamic braking controls. Dart's zero-speed detect circuit also eliminates motor plug reversing problems. In the event of a power loss or emergency stop condition, the 130 Series control will drop into a dynamic brake condition to safely and quickly bring the motor to a stop and remain there until power is reapplied and a run condition is recognized. The 130 Series control comes in a compact package and fits the industry standard footprint for both vertical and horizontal mounting.
