AMP 2 is a Quad H-Bridge Low Power Drive in a 3U UMAC form factor designed to drive DC brushed type motors, galvanometers, piezoelectric motors, voice coil motors, or proportional hydraulic valve actuators. This amplifier provides four channels of 80 W continuous analog power. The QUAD H-Bridge Low Power Drive may be interfaced conveniently to the PMAC controller via ACC-24E2A or ACC-24E3 (Power only). The maximum bus voltage for this amplifier is 40 VDC and the continuous rating for each drive is 2 A. The amplifiers on this product will output a current that is proportional to the voltage input. The amplifier was designed to be used with torque or current command inputs from the controller but if the controller has microstepping capabilities, the user can also use the product to drive stepper motors.
