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 for low-voltage applications) and converts it to stable DC power via a 6-pulse rectifier (DC link voltage: 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 loads like fans) and vector control (for precise torque demands like compressors).

• Efficiency & Power Density: Delivers a maximum efficiency of 98% (at 75% load) and features a compact design (200mm × 280mm × 110mm typical)—saving 30% of cabinet space vs. legacy modules and reducing heat generation, which lowers cooling system costs.

• 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 "auto-parameterization"—automatically detects the control unit and loads optimized settings, eliminating manual configuration and cutting setup time by 65%.

• Dynamic Load Handling: Integrates Siemens’ "Adaptive Torque Control" to manage sudden load spikes (up to 150% rated torque for 60 seconds) and "Energy Optimizer" to adjust switching frequency (2kHz–16kHz) based on load—minimizing switching losses at light loads (e.g., 30% energy savings for partial-load fans).

• Protection & Safety Features:

• Multi-Layer Fault Shielding: Equipped with overcurrent protection (trip current: 125% rated current), overvoltage protection (DC link cutoff at 750V), undervoltage protection (DC link cutoff at 350V), and overtemperature protection (shutdown at 85°C module temperature). Includes short-circuit protection for input (line-to-line) and output (motor terminal) circuits, preventing module and motor damage.

• Safety Compliance: Integrates "Safe Torque Off" (STO) function meeting SIL 2/PL d standards—cuts motor torque without disconnecting main power, enabling safe maintenance and avoiding unintended startup in high-risk areas (e.g., food processing washdown zones).
