• QC 3000 – The QC 3000 was designed for use as an infeed motor velocity control on a woodworking IC Planer. A current sensor is used to sense the load on the planer motor. As the planer motor load increases, the infeed motor controlled by the QC 3000 will reduce velocity. The opposite is true when the load on the planer motor drops. This maintains constant loading on the planer motor to create a smooth finish without burning the lumber.
• QC 4100D – This drive is a universal DC brush motor velocity control. It is a single-quadrant analog drive (unidirectional), and is available as either a 12 VDC or 120 VAC drive. QCI can supply with or without the speed pot. Rectangular board. In stock.
• QC 4100F – This drive is the most universal DC brush motor velocity control. It is a single-quadrant analog drive (unidirectional). It is available as either a 12 VDC or 120 VAC, or 120 / 230 VAC drive. QCI can supply with or without the speed pot. Square board.
• QC 4400 – This drive is custom designed to mount on an extended housing on the back of a 3” PMDC Brush Motor. It is available in 12VDC and 120VAC models, and is used to control a unidirectional pump motor. In addition to the three speed control buttons it also has an enable / disable input. It is microprocessor controlled so a program change can redefine the use of the buttons and LED indicators.
• QC 4500 – QCI designed this 12 VDC controller for bidirectional control of PMDC brush motors. Originally designed for a mobile 3 axes lift, it is the most flexible multi-axis PMDC brush motor controller available. Direction is signaled through digital I/O on the board, which causes a polarity change via on-board relays to the motor leads. This controller can control two motors simultaneously, with a third motor connected for non-simultaneous motion. Encoder inputs allow synchronization of two motor velocities. A microcontroller is used, so if the hardware fits new applications can be programmed.
• QC 5800 – This 120 / 230 VAC closed loop velocity brushless DC drive was originally designed for high performance athletic and medical treadmills. Closed-loop control eliminates the need for a fly wheel, and provides a higher response to load and speed changes of the runner. It is provided with a CAN Bus interface for communication to the main operator controls, and also allows data acquisition of runner performance if required.
• QC 6200 – This unit is designed for use as an analog 4-quadrant (bi-directional) positioning controller. It uses 24 VDC input power as an analog drive for PMDC brush motors. Originally designed for use with brush motor-style linear actuators, it closes the position loop with analog linear or rotary potentiometers. In stock.
• QC 6210 – This drive is a higher performance surface-mount version of the QC6200. It operates on 10 to 36 VDC, and can provide up to 30 AMP continuous output for larger PMDC brush motors. In stock.
• QC 6300 – This microcontroller-based drive is designed as a fully-closed-loop servo controller utilizing encoder feedback. It offers a full complement of digital and analog I/O and includes a Can Bus network interface option. Originally designed for use to mount inside a custom extruded housing, the drive can be be re-laid out for more general mounting arrangements, and is an ideal design platform for use with common NEMA 23 and 34 brushless DC motors. It can provide up to 20 amps continuous output.
• QC 6400 – The QC 6400 series controllers are available in both AC and DC input power versions, and were originally designed for use with furnace blowers as a single-phase brushless DC motor controller. Available up to 4 HP, they can be mounted on the back of a NEMA 56 motor with the proper mounting hardware (to be supplied by the motor manufacturer).
• QC 120/130 VAC Dual Drive – This 120 / 230 VAC drive was designed to control 2 brushless DC motors at a programmable velocity ratio of one to the other. It was designed to control a dual-chemical dispensing pump requiring a close velocity ratio of one to the other. A master controller, provided by the customer, communicates velocity change (speed and ratio) via a serial interface.
• SPS-100-88-21091 – This 120 / 21091 Frequency Trip Switch – This automatic starter disconnect is used on diesel-powered electric generators. In stock.
