Basic information model: A5E02268102
Device type: Siemens MM440 series frequency converter surge filter/rectifier absorption board
Compatible models: MM440 45kW, 55kW, 75kW (380-480V, compatible with current of about 90A-150A power module)
Core application: Suppress surge voltage on the grid side, absorb rectifier bridge shutdown spikes, protect the power module and control circuit of the frequency converter, and improve the EMC performance of the system
Electrical parameters Operating voltage: three-phase 380-480V AC, compatible with 50/60Hz power grid
Surge suppression level: line to line: differential mode 10kV, line to ground: common mode 15kV
Absorbing element: High voltage non inductive capacitor (about 10 μ F/1200V)+silicon carbide varistor (MOV) combination
Rated current: Continuous operating current 10A (peak value under surge conditions can reach 2000A/2ms)
Interface type: three-phase input terminal (compatible with MM440 standard incoming copper busbar), DC output terminal (connected to the DC side of the rectifier bridge)
Protection functions: overvoltage protection, overcurrent protection, component overheating protection
Physical and environmental parameter structure form: onboard installation, compatible with MM440 standard power unit card slot
Protection level: IP20 (to be installed inside the frequency converter cabinet)
Working temperature: -10 ℃ -50 ℃
Storage temperature: -25 ℃ -70 ℃
Cooling method: Natural heat dissipation (relying on the air duct inside the inverter cabinet for auxiliary heat dissipation)
Dimensions: Approximately 220mm x 150mm x 40mm (width x height x depth)
Weight: Approximately 0.8kg
Adaptation and functional adaptation components: MM440 series 45kW -75kW power modules, rectifier bridge components
Functional features: differential/common mode surge suppression, rectification peak voltage absorption, EMC filtering, contactless signal output in fault state
Installation requirements: Installed between the input side of the frequency converter and the rectifier bridge, the wiring should be tightened to avoid looseness and heat generation
