Overview: The Servo Amplifier PMA 90/180 by PML FlightLink Limited is designed to control both brushed and brushless motors, offering a compact design with a small footprint. It features a 40kHz PWM frequency, which is double that of most conventional drives, allowing direct connection to PML motors without an external choke.

Specifications: The amplifier supports brushed DC motors, low inductance printed armature motors, and brushless DC motors up to 750W. It operates with a single power supply ranging from 18 to 180VDC, providing up to 20A peak and 12A continuous current. The device includes adjustable input gain, loop gain, offset parameters, and configurable peak and continuous current limits.

Features: Key features include amplifier enable and direction enable inputs, full motor/drive protection, potentiometer operation for reference signal, and adjustable peak current time from 50 ms to 3 sec. It also offers comprehensive short-circuit protection, an internal fast-blowing fuse, over/under voltage shutdown, and four quadrant regenerative operation.

Benefits: The PMA 90/180 is noted for its small footprint, low cost, and ease of use. It provides high acceleration without sacrificing protection against continuous overloads and ensures no integrator windup during power-up or if the amplifier is disabled.

Supported Motors: The amplifier supports brushless DC motors with 60º/120º commutation, brushed DC motors, and printed armature DC motors.
