Stepper motor amplifier JK1545DC - Digital amplifier for precise stepper motor control
The JK1545DC stepper motor power amplifier is a powerful digital controller for 2-phase stepper motors and is ideal for CNC milling, laser systems, engraving machines, positioning systems and automation technology. Thanks to modern microstep technology, the power amplifier ensures one quiet, low-vibration motor running and high precision in positioning tasks.
With a supply voltage of 20 to 50 volts DC and an adjustable motor current of up to 4.5 amps The JK1545DC is particularly suitable for NEMA 17, NEMA 23 and smaller NEMA 34 stepper motors. Intelligent digital power control reduces motor heating while improving torque and smoothness.
The Microstep resolution enables precise movements and fine-tuned positioning for demanding CNC applications. Current strength and step resolution can be conveniently adjusted via integrated DIP switch adapt, which enables optimal coordination with the stepper motor used.
The control takes place via standardized Step/Dir signals (PUL/DIR) and is compatible with many common CNC controls such as Mach3, Mach4, LinuxCNC, PlanetCNC, DDCSV and GRBL-based controls. In addition, the power amplifier has protective functions against Overcurrent, overvoltage and overheating, which ensures safe operation.

Important note – discontinued model
The JK1545DC stepper motor power amplifier is a discontinued model and is only available to a limited extent. As a technical one Replacement item we recommend that DM542EU stepper motor power amplifier, which offers comparable performance data and can be used as a modern successor for many applications.
The DM542EU also supports 20-50V DC supply voltage, a motor current of up to 4.2 A, Microstepping operation as well as the standardized one Step/Dir control (PUL/DIR). It is ideal for NEMA 17, NEMA 23 and NEMA 24 stepper motors and convinced by one quiet running, high precision and reduced engine heating.
Thanks to modern digital signal processing and optimized anti-resonance technology, the DM542EU is a reliable and powerful alternative to the JK1545DC and is ideal for CNC milling, laser systems and automation applications.
