If you're looking for big time stepper performance from a small driver, the MLA05101 is your answer. This powerful microstepping driver provides excellent torque in a compact and low profile encloser. The MLA05101 is also very easy to use. It features rugged terminal blocks, a rotary pot for current settings, and a visible silkscreen for easy installation. Versatile as well as powerful, the MLA05101 has a wide amperage range. It is designed to handle small stepper motors rated as low as 0.75 Amps/phase, mid-sized steppers such as NEMA 23 and 34, as well as larger motors with current ratings up to 5.0 Amps. It operates from an AC voltage of 90-132 Volts, making it a great fit for almost any stepper application. The MLA05101 features optically isolated inputs that are 3.5 - 8.6VDC compatible. The clock input can be set to receive either sinking or sourcing clock signals at frequencies up to 100KHz. The driver also features direction control, motor on/off capabilities, and a built in short circuit and miswire shutdown protection. The MLA05101 is a bipolar type driver designed for use with 4, 6, or 8 lead stepper motors, making it compatible for series and parallel installations. The driver has a 2000 steps per revolution or 0.18° per step resolution,with respect to a 1.8° stepper motor. It also has a motor current reduction feature that will help keep stepper motors cool at standstill, and LEDs that indicate power and pulses being received. Ideal Applications: Automated machinery or processes that involve food, cosmetic, or medical packaging, labeling, or tamper-evident requirements, cut-to-length applications, electronic assembly, robotics, factory automation, special filming and project effects, medical diagnostics, inspection and security devices, conveyor and material handling systems, metal fabrication (CNC machinery), pump flow control, XY and rotary tables, equipment upgrades or wherever precise positioning or speed control is required.
