Product Name: MMC Smart Drive External Shunt Resistor Module (12.0 kW, 460 V)
Product Introduction: Similar to the 8.0 kW version, this is a high-capacity external braking resistor for 460 V servo drive systems, rated for 12.0 kW continuous dissipation.
Detailed content
Technical Specifications:
-
Continuous Power: 2800 W
-
Peak Power: 32 kW
-
Resistance: 25 Ω
-
Max Voltage: 850 V DC
-
Time Constant: 60 sec

Dimensions: Approx. 171 x 430 x 550 mm
Structure: Heavy-duty resistor grids in a protective frame, designed for panel or stand-alone mounting with adequate clearance.
Applications: Very large inertial loads, multi-axis gantries, heavy press deceleration.
Installation & Safety: Requires significant mounting space and cooling air. Terminals are high-voltage; lock out before servicing. Use ferrules on wire ends.
Operating Considerations: Resistor surface temperatures can exceed 200°C during peak braking. Install thermal protection or guarding if personnel access is possible nearby.
