Frequently Asked Questions
Q What is the model number of this power module and what is its rated output current?
A The model is 230D20NZ-D. It features a rated output current of 20A with a total power of 6KW, making it suitable for high-demand industrial charging and power supply applications.
Q What input voltage range does the 230D20NZ-D module support?
A The module accepts an AC input voltage ranging from a minimum of 323VAC to a maximum of 437VAC, with a typical operating voltage of 380VAC, suitable for standard three-phase industrial power grids.
Q How does the automatic current limiting and short circuit protection work?
A When an overload occurs, the module automatically limits the output current to no more than 110% of the rated current, preventing infinite current growth. In the event of a short circuit, the module activates self-protection and is self-recoverable once the fault is cleared.
Q Does this module support hot swapping and remote monitoring?
A Yes. The 230D20NZ-D supports hot swapping for easy maintenance without system shutdown. It also features a standard RS-485 interface and CAN interface, enabling full “4-remotes” functionality (remote sensing, remote signaling, remote control, and remote adjustment) for seamless integration with automation systems.
Q What is the efficiency level of this power module and how is current sharing managed?
A The module achieves a high efficiency of ≥94%. It uses isolation automatic current sharing technology to ensure balanced load distribution among parallel modules, with a current share imbalance of no more than ±3%, ensuring stable and reliable system operation.
Q What are the operating and storage temperature ranges for this module?
A The module operates reliably within a working temperature range of -10℃ to 40℃ (typical 25℃). For storage, it can withstand temperatures from -40℃ to 60℃, making it suitable for a wide range of industrial environments.
