System Architecture & Signal Flow
The PFC0750-3AH-N operates as a boost-topology active PFC front-end. Three-phase AC input is rectified and then processed through a high-frequency switching stage that shapes the input current waveform to follow the input voltage sinusoid, achieving near-unity power factor. The regulated ~400 VDC output bus feeds downstream isolated DC/DC converter modules.
Typical System Block:
3Ø AC Mains (200–480 VAC) → EMI Filter → PFC0750-3AH-N (Active PFC + Boost Converter) → 400 VDC Regulated Bus → TDK-Lambda DC/DC Modules (e.g., i7C, EFE, HWS Series) → Load (Servo Drives / PLC I/O / Sensors)
This architecture ensures that the downstream DC/DC stage operates from a stable, pre-regulated bus, maximizing overall system efficiency and simplifying output regulation design.

Technical FAQ
Q: Can the PFC0750-3AH-N operate on single-phase input?
A: No. This model is designed exclusively for three-phase AC input (200–480 VAC). For single-phase applications, refer to TDK-Lambda’s PFC400 or PFC600 single-phase series.
Q: What is the inrush current at startup?
A: TDK-Lambda incorporates soft-start circuitry to limit inrush current. Refer to the official datasheet for peak inrush values specific to your input voltage.
Q: Is the output voltage adjustable?
A: The DC bus output is internally regulated to approximately 400 VDC. Fine adjustment capability depends on the specific variant — consult the datasheet or contact Konmask.com for clarification.
Q: What downstream TDK-Lambda modules are compatible?
A: The PFC0750-3AH-N is designed to interface with TDK-Lambda’s i7C Series, EFE Series, and HWS Series DC/DC converters that accept a 400 VDC bus input.
Q: What is the warranty period?
A: TDK-Lambda standard warranty applies (typically 3 years from date of manufacture). Konmask.com provides additional after-sales support for the duration of the warranty period.
Q: Do you provide export documentation for international orders?
