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 for low-voltage setups) and converts it to stable DC power via a 6-pulse rectifier (DC link voltage: 540V–670V). Inverts DC to variable-frequency 3-phase AC output (0–500Hz) for motor control, supporting V/f control (simple loads) and vector control (precise torque applications like compressors).

• Efficiency & Power Handling: Delivers 98% maximum efficiency (at 75% load) and handles continuous current up to 400A (depending on specific variant), with a compact design (220mm × 320mm × 120mm typical) to save cabinet space in medium-power installations.

• Sinamics G220 Compatibility & Integration:

• Drive-Specific Design: Exclusively compatible with Sinamics G220 inverters, connecting to G220 Control Units (e.g., CU250D-2 PN) via Siemens’ proprietary backplane bus. Supports "auto-configuration"—automatically syncs with the control unit to load optimized parameters, reducing setup time by 70% compared to manual configuration.

• Advanced Load Management: Integrates Siemens’ "Dynamic Power Control" to handle sudden load spikes (150% rated torque for 60 seconds) and "Smart Energy Mode" to adjust switching frequency (2kHz–16kHz) based on load, minimizing energy waste in partial-load scenarios (e.g., 25% savings for pumps with variable flow demands).

• Protection & Safety Features:

• Multi-Layer Fault Protection: Equipped with overcurrent protection (125% rated current trip), overvoltage protection (DC link cutoff at 750V), undervoltage protection (DC link cutoff at 350V), and overtemperature protection (shutdown at 85°C). Includes input/output short-circuit protection to shield the module and motor from damage.

• Safety Compliance: Features "Safe Torque Off" (STO) meeting SIL 2/PL d standards, allowing safe maintenance by cutting motor torque without disconnecting main power—critical for high-risk environments like chemical processing plants.
