Description
Technical Specifications: Continuous Output Current: 20A; Input Power: 110/220V AC selectable; Control Modes: Torque mode, Velocity mode; Feedback Support: Tachometer generator, incremental encoder; PWM Switching Frequency: 16kHz; Command Input: ±10V analog differential; Operating Temperature: 0°C to +55°C
Function Features: Adjustable current limit; built-in overcurrent, overvoltage and thermal shutdown protection; gain and offset trim potentiometers; current monitor output signal; inhibit and enable control inputs
Application Scenarios: Converting machinery, material handling conveyors, medical automation equipment, test and measurement systems, retrofitted legacy DC servo systems
Performance Parameters: Current regulation accuracy ±2% of setpoint; speed regulation better than 0.5% with tachometer feedback; response time less than 10ms for 100% step change
Material Composition: Aluminum extrusion heat sink chassis, power MOSFET switching devices, FR4 printed circuit board, steel mounting brackets
Structural Features: Chassis-mount compact design; front-access trim pots for gain and offset adjustment; screw terminal connections for power, motor and control signals; natural convection cooling structure
Working Principle: Rectifies AC input to DC bus voltage; uses high-frequency PWM switching to regulate output voltage and current to DC motor; compares feedback signal with analog command input to adjust output and maintain closed-loop control
Installation Requirements: Mount vertically for optimal natural convection cooling; maintain minimum 50mm clearance above and below heat sink; separate low-level control wiring from power cables; use shielded cable for motor and feedback connections
Usage Notes: Set current limit to match motor rated continuous current; verify heat sink temperature during extended full-load operation; do not operate with open motor circuit for extended periods; power off before adjusting internal trim pots
