Core Features

• 10 kW Compact Integrated Design: 60 mm width with all key components (brake chopper, resistor, energy buffer) integrated, saving cabinet space and reducing external wiring.

• High Overload Capability: 250% nominal power for 1 second, ideal for dynamic acceleration/deceleration in high-cycle machinery.

• Low Harmonic Distortion: Optimized charging currents and high effective current percentage minimize THD and reactive power, improving energy efficiency.

• Integrated Energy Buffer: 250 Ws storage smooths DC link voltage fluctuations during peak loads, enhancing system stability.

• Simplified Installation: No external braking resistor required; plug-and-play backplane connection to MXM/MXA modules reduces setup time.

• Advanced Diagnostics: 7-segment display and multi-color LEDs for real-time status, voltage, current, and fault monitoring.

• Comprehensive Protection: Overvoltage, undervoltage, overcurrent, overtemperature, short-circuit, and ground-fault protection.

• Flexible System Expansion: Supports up to 8 standard MXA axis modules, scalable for small-to-medium multi-axis systems.

Typical Applications

• Small Machine Tools: CNC routers, drilling machines, and light milling centers with 2–4 synchronized axes.

• Packaging Machinery: Compact forming, filling, and sealing lines with moderate cyclic power demands.

• Material Handling: Light conveyors, pick-and-place units, and small cranes with frequent start-stop cycles.

• Textile Machinery: Small spinning, weaving, and knitting machines with multi-axis synchronization.

• General Automation: Any 10 kW multi-axis servo application requiring compact, cost-effective, and low-wiring power supply.
