Frequently Asked Questions
Q
What is the rated output current and power of the 230D10NZ-D module?
The 230D10NZ-D delivers a rated output current of 10A and a power output of 3KW. Under overload conditions, the automatic current limiting feature restricts the output to a maximum of 110% of the rated current.
Q
How many modules can be connected in parallel, and how is current balance maintained?
Up to twenty modules can be connected in parallel. The unequal current ratio of parallel connection is kept within ±3%, ensuring stable and balanced current sharing across all modules in the system.
Q
What is the efficiency of this rectifier module?
The module achieves an efficiency of up to 95%–96%, with a minimum guaranteed efficiency of ≥94%. The full bridge rectifying circuit and reactive PFC design contribute to a power factor greater than 0.94, making it highly energy-efficient.
Q
What input and output voltage ranges does this module support?
The module accepts a 3-phase AC input from 323V (min) to 437V (max), with a typical operating voltage of 380VAC. The DC output voltage ranges from 176V (min) to 300V (max), with a typical value of 242VDC.
Q
What protection features does the 230D10NZ-D include?
The module includes multiple protection mechanisms: over voltage protection activates at 320±15VDC; short circuit protection automatically isolates the module from damage and is self-recoverable; automatic current limiting prevents output current from exceeding 110% of the rated value; and reverse connection protection is also built in.
Q
What communication interface does this module support, and what remote functions are available?
The 230D10NZ-D is equipped with an RS-485 communication interface, enabling "4 remote control" functions: remote signaling, remote measurement, remote control, and remote adjustment. This allows seamless integration into centralized monitoring and management systems.
