This servo amplifier uses pulse-width modulation (PWM) for efficient power delivery, supporting bi-directional motor control with fast response and minimal thermal load. It integrates feedback signal processing and current loop regulation, essential for dynamic performance in closed-loop motion systems. Technical Specifications Model: 709-138 Manufacturer: QMC Technologies Designed for: Universal Instruments automation systems Amplifier type: Switching (PWM) servo amplifier Motor type supported: Brushed DC servo motors Output voltage: Typically ±60 V DC (based on system supply) Output current: Nominal 10 A continuous, up to 20 A peak (model-dependent) Input voltage: ±80 V DC (typical max bus voltage, verify system source) Control mode: Current loop (torque control), velocity loop (via external controller) Feedback supported: Tachometer or encoder input (varies by configuration) Switching frequency: Typically 20 kHz (quiet operation with minimal ripple) Protection features: Overvoltage, overcurrent, thermal shutdown, short-circuit protection Signal interface: Analog input (±10 V), enable/disable logic, fault output Cooling: Convection or fan-cooled depending on installation Mounting: Panel or rack-mountable Form factor: Eurocard or proprietary format (used in Universal Instruments chassis) Connectors: Edge card or ribbon-style depending on vintage Application: Placement machines, pick-and-place arms, precision motion stages Notes This is a legacy component; compatibility is specific to certain Universal Instruments platforms. Replacement may require calibration or firmware alignment with the host controller. Often integrated with motion controllers or CNC backplanes specific to the assembly line equipment.
