Description
The Haas Servo Amplifiers 93-32-3551J (45 Amp) and 93-32-5550J (30 Amp) are genuine OEM drive modules designed for Haas Automation CNC machines (VF, VM, EC, Mini Mill, and lathe series). These amplifiers interface directly with the Haas Main Control Board / I/O PCB and accept 320V DC link power from the Haas vector drive power supply. They provide closed-loop current control for Haas brushless servo motors (e.g., 3.5 HP / 5 HP / 7.5 HP axis motors depending on axis load). Fully tested units are functionally verified before shipment to ensure drop-in compatibility.
