The Okuma BLII-D75A is a 1-axis brushless AC servo drive amplifier from the BLII-D series (3rd generation), with power unit capacity 75 A (peak/current limit). Compatible with motors requiring 15 A, 30 A, 50 A, or 75 A rated current; supports variable configurations via jumper/switch settings. Input: 3-phase AC 200–220 V; output: variable 3-phase AC for BL/PREX series motors. Features optical interface for OSP CNC controls, PWM control, and high-response servo loop. Forced-air cooled; robust for precision axis feed in Okuma CNC machine tools. [stock available]
