The AGA155 series is a family of 220VAC Central-i remote power amplifiers. AGA amplifiers are controlled by AGM series Central-i master, which gets encoder reading and current samples from each amplifier, performs control loops calculation and generate PWM commands to each amplifier. Fast Central-i fieldbus is used to communicate between AGA amplifiers and AGM master, that allows 16kHz sample rate motion profiler and all servo loops. The AC powered remote amplifier is capable of driving motor up to 10 Arms continuous and 20 Arms peak current. The amplifier comes with heat sink and cooling fan, is ideal for high power motors, including big direct drive linear and rotary motors. Similar to the DC powered AGA10x amplifiers, the AGA155 amplifier also comes with digital and analog I/Os sufficient for a typical actuator and application. The isolated digital outputs are capable of sourcing up to 300mA or sinking up 500mA. This is sufficient to drive most external devices, end effectors, etc, hence, eliminated the need to have an external relay circuit.
