The 150D Series from Dart Controls sets a new standard for SCR drive design. The 150D Series was developed specifically with the OEM in mind, with standard features and convenient options required for most applications. The 150D Series is also a drive designed with the future in mind – a development platform which will soon incorporate new features not found anywhere else in the market. The 150D Series is a superior choice for new and existing applications – it will directly replace other drives on the market without changing mounting dimensions or wiring terminations.

The state-of-the-art Surface Mount Electronics offers a circuit that is flexible and responsive, with high power density in a small footprint. Dart’s adjustable HP design eliminates the need to manage clumsy HP resistors. In the open chassis model, two wiring terminations are available – spade terminal (standard) and euro-style terminal strip. Fusing options allow for fusing AC line, motor armature, or both; all at the user’s discretion. For OEM’s with ex-US sales, some models offer 90VDC output with either 120 or 240VAC supply voltage. The printed circuit board has been designed to add components to support single or multiple fixed speeds using a switch input. PCB board sockets allow for the development of specific, custom options the OEM may require. Board mounted LED’s verify the presence of supply voltage, and whether the drive is in an over-current condition.

The -HSK auxiliary heat sink doubles the HP capacity when larger motors are used. An important feature of the -HSK is it uses the SAME mounting hole pattern as the base control, with a modest 4.25″ x 4.25″ space conscious footprint.

Please call Dart Controls to order your no charge, no obligation sample of the 150D Series. Our application specialists are always available to discuss your specific drive needs.

Dart Controls continues its investment in the development of rugged and dependable DC drives. The 125DV200E is the latest example. The cast aluminum powder coated enclosure available in both black and white is rated NEMA 4X for wash down, outdoor and food/sanitary applications. One drive will handle both 120VAC and 240VAC source power for motors from 1/4HP through 2HP. Dart’s standard auto-sensing voltage circuit means no jumper settings or wiring changes are necessary. The drives are fully adjustable across their HP ratings – no extra resistors to purchase or keep track of. Options include adjustable linear ACCEL and DECEL; voltage and current follower isolated inputs.

A compact, cost-efficient, reliable control for PM, Shunt Wound DC motors and Universal motors. The 125 Series variable speed control incorporates up-to-date design and engineering into an amazingly small package. Installation and field adjustment are facilitated using a barrier type terminal strip and large, easily adjusted trimpots. Adjustable horsepower range – 120VAC, 1/50 through 1/8 HP and 1/4 through 1/2 HP; 240VAC, 1/25 through 1/4 HP and 1/8 through 1 HP. Standard features include an inhibit circuit for start-stop operation and 1% speed regulation over a 50:1 speed range. Dual voltage 120/240VAC or 24/36VAC models are available. Long life and quality are assured by 100% full load testing. The 125 Series is ideal for applications such as: office machinery, conveyors, packaging equipment, printers, process equipment, centrifuges, and exercise equipment.

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.

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.

Dart’s top of the line DC speed control is reliable, versatile, and economical. Rated to 3 horsepower, it provides many standard features typically offered as options. The Dart 500 Series control combines advanced engineering design, careful component selection and rigorous quality control to deliver an excellent off-the-shelf SCR control. Dependable, time-proven circuitry offers performance characteristics previously available only in more costly controls. While providing a wide range of standard features, many options quickly and easily extend the 500 Series capabilities to meet specific application requirements. An integral part of a distinguished line of quality products, the 500 Series is representative of Dart’s continuing effort to provide reliable, versatile controls to the OEM, distributor, and the industrial market.

The Dart VSI2 (speed signal isolator) permits the user to control the output of a variable speed motor drive from any external grounded or ungrounded DC input signal. A single model accepts a wide range of input voltages (0-5 through 0-25VDC or 0-25 through 0-250VDC) AND 4-20mA. The VSI2 incorporates Dart’s unique feedback circuit, which virtually eliminates output changes due to the thermal drift of logic components. The VSI2 is packaged in an aluminum chassis mount housing and contains an on-board power supply for its logic circuit. An electrical isolation rating of 2500Vrms is achieved by the use of an optically isolated IC package. The Dart VSI2 can be used with virtually any motor speed control that has a speed reference circuit of +5 to +15VDC and an input impedance greater than 47K ohms. The output of the VSI2 is a filtered, pulse width modulated signal that is directly proportional to the input speed signal. The wide input range allows the VSI2 to follow signals as low as +0-5V logic levels and up to the 180VDC levels present at the armature leads of a 180VDC motor. By simply connecting the input terminals across the armature leads of a “master motor”, you can use the VSI2 for master/follower operation. The addition of a scaling pot will provide for proportional follower operation.
