The MC10-R accepts 115 or 230VAC input for operation of 90 and 180VDC permanent magnet or shunt wound DC motors (50/100/200VDC field voltage) from 1/8 to 2 horsepower. Included are power and current limit LEDs, line fuses, inhibit pins for remote start/stop and mounted on the front cover are a speed potentiometer and On/Off switch. Setup is easy with trimmer pot adjustments for minimum speed, maximum speed, acceleration, deceleration, IR compensation and current limit and a screw terminal block for easy wire connections.

The MM23011C drive is a reliable and cost-effective solution for controlling your permanent magnet or shunt-wound DC motors in variable-speed applications. It uses SCRs to provide full-wave rectification of the AC line input. This dual voltage drive operates using 115 VAC or 230 VAC, 50/60 Hz, to operate 90 or 180 VDC SCR brush-type motors from 1/20 to 1/4 HP. Packaged in a compact footprint, this user-friendly drive possesses diagnostics and options to accommodate user needs.

The MM301A dual-voltage single quandrant SCR drive controls 90 or 180 VDC SCR brush-type motors ranging from 1/4 Hp through 2Hp. The MM301A has integrated isolation allowing it to precisely follow analog current or voltage signals from external devices or a potentiometer as a reference for motor speed control. This results in significant labor and material cost reduction compared to other systems employing a seperate drive and isolation card. This multi-featured chassis drive accepts optional input for start and stop. Depending on the application, users can run the drive open-loop with armature feedback or closed loop with tachogenerator feedback for enhanced performance. This drive accepts nearly any DC tachogenerator (7-50 V/KRPM), scaleable using an adjustable tachogenerator gain potentiometer.

Minarik Drives has always been a leader in providing low cost PWM motor controls. With the MMXL05-D240AC-PCM, we have done it once again! We have taken a full-featured PWM drive and reduced it down to the standard MM footprint (4.30 X 3.64). Not only did we keep all the features of the larger XL Series, but we even added optical isolation to the speed circuit and the inhibit circuit in the -PCM model. This means that the speed can be controlled with any 0-5 VDC signal and many drives can be inhibited with a single contact closure. The auto-ranging power supply allows the user to apply 120 or 240VAC without adjusting any switches. The full-featured MMXL05-D240AC-PCM is one of the smallest PWM drives on the market today!

The M2-D drive provides the power of two drives in one! Now with one DC drive, you can control two different DC motors either independently or in a ratio mode. The M2-D now has a dual voltage 115/230 VAC input In independent mode, each side of the M2-D can be controlled differently with different trimmer pot settings and different speeds. In speed ratio mode, one speed potentiometer sets the main speed while the other one determines the ratio of the speeds between the motors. In this mode, the drive replaces two single drives and possibly a separate master/follower card too resulting in extreme cost and panel space savings The M2-D drive is easy to set up with simple jumpers to choose the modes speed/torque and independent/ratio. In speed mode where speed is controlled, the external potentiometer sets the speed reference signal and the current limit trimmer pot sets the current limit. In torque mode, the external potentiometer sets the torque reference and the current limit trimmer pot sets the runaway speed limit. Set up parameters are easily adjusted with onboard trimmer pots. For OEMs that have fixed settings, the M2-D drive is microprocessor based and can have the settings or ranges of the trimmer pots and other functions customized without any hardware changes The M2-D drive is ideal for applications with two DC motors that are working together, two motors that run independently but are physically close or simply when panel space is very limited.

Specifically designed for the original equipment manufacture (OEM), the XP10-115AC DC motor speed drive provides high performance at a low cost. This drive is well suited for XL series drive candidates who do not need all of its features. The XP10-115AC takes an AC line input, rectifies it and filters the output to create a DC bus that is chopped by pulse-width-modulation (PWM) circuitry to provide nearly pure DC power to the motor. The result is a form factor of 1.05 or less throughout the entire 80:1 speed range; compared to a 1.37 form factor from standard unfiltered SCR dirves. The near unity form factor results in smooth, quiet, cool and low maintenance motor operation. In addition, the low form factor allows drives to operate lower voltage motors without additional circuitry. The XP10-115AC drive is versatile and can accept any AC voltage between 70 and 130VAC and contain a unipolar power supply, which enables the drive to accept DC (100-160VDC); unlike typical transformer-coupled drives. Depending on your application needs, this drive will provide speed control for motors ranging from 1/4 through 1 HP.

Minarik Drives' standard MM23401C drive is housed in a NEMA 4X enclosure guaranteeing protection from washdown applications, corrosive material, wind-blown dust, incidental contact with enclosed equipment or unwanted external solid objects. The MM23401C provides sound performance for DC brush-type motors from 1/8 to 2 HP. This stand-alone cased drive contains a neon power light, pre-mounted heat sink, power switch, and speed adjustment knob accessible from the front of the enclosure. Using full-wave rectification of the AC line input, this SCR drive provides a 60:1 speed range. Users make all wire terminations at the screw terminal block inside the enclosure. The dual voltage capability allows these drives to operate from 115 or 230 VAC, 50/60 Hz, to run 90 or 180 VDC motors.

Minarik's RG25U, controls brush-type DC motors for applications that require bi-directional variable speed and smooth motoring or braking torque in either direction of rotation. The RG25U is ideal for OEMS: This half-wave SCR drive delivers 1/8 through 1/2 HP. The compact size and low-cost distinguishes it from other regenerative drives on the market. The RG25U drive uses the same chassis as our popular single-quadrant SCR drive, the MM23001C. It is one of the smallest 1/2 HP regens on the maket. Applications with overhauling loads, rapid deceleration, basic positioning and high duty cycle reversing and braking benefit from this versatile regenerative drive. The RG25U drive is ideal for low duty cycle applications.

Similar to our MM23000C series in length and width, the ''piggyback'' design allows for many features in a small package. The MM10-115AC-PCM series drive accepts non-isolated voltage (0-10VDC) or current (4-20mA) signals coming from an in-plant process, programmable logic controller, motion controller, etc. to control speed. A quick connect removable terminal block allows users to quickly detach the drive without disconnecting the wires from the terminal block. Also included is an optically isolated normally-closed stop and normally-open start input. This allows remote starting and stopping of the motor with switches or pushbuttons.

For cost sensitive variable speed applications requiring outstanding performance, Minarik Drives offers the SQ16U drive. This light-weight compact drive controls DC brush type motors ranging from 1/50 to 1/4 HP, without any additional components required.
