Core Functions & Specifications

• AC-DC-AC Power Conversion:

• Input/Output Parameters: Accepts 3-phase AC input (380V–480V AC, 50/60Hz; optional 200V–240V AC variants) and converts it to stable DC power (via a 6-pulse rectifier) with a DC link voltage of 540V–670V. Inverts DC power to variable-frequency 3-phase AC output (0–500Hz) for motor speed control, supporting both V/f control (for simple applications like fans) and vector control (for precise torque demands like compressors).

• Efficiency & Power Density: Boasts a maximum efficiency of 98% (at 75% load) and a compact design (180mm × 250mm × 100mm typical), saving cabinet space and reducing heat generation—critical for dense industrial control panels.

• Sinamics G220 Compatibility & Integration:

• Drive-Specific Matching: Designed exclusively for Sinamics G220 inverters, connecting seamlessly to G220 Control Units (e.g., CU250D-2 PN) via Siemens’ proprietary backplane bus. Supports "parameter cloning"—automatically inherits drive settings from the control unit during installation, eliminating manual configuration and reducing setup time by 60%.

• Load Adaptation: Integrates Siemens’ "Energy Optimizer" algorithm, which adjusts switching frequency (2kHz–16kHz) based on load conditions (e.g., reducing frequency at light loads to minimize switching losses). Also supports "Dynamic Torque Control" to handle sudden load spikes (up to 150% rated torque for 60 seconds), preventing motor stalling in applications like conveyor jam recovery.
