Frequently Asked Questions (FAQ)
Q1: What communication protocols and interfaces does the module support?
The module features a standard RS-485 serial communication interface, supporting “4-remotes” functions. It can achieve automatic control including module switch on/off, charging mode conversion, output voltage/current setting, and SYNC switchover.
Q2: Does the power supply support hot-swapping and parallel expansion?
Yes. It is engineered with a modular design supporting N+1 hot backup and smooth system expansion. The modules are fully hot-swappable with isolation automatic current sharing technology (unevenness <±3%).
Q3: What are the input and output voltage ranges for model 110D20NZ-5?
The AC input voltage range is 323 VAC to 437 VAC (typical: 380 VAC). The adjustable DC output voltage range is 88 VDC to 150 VDC (typical: 121 VDC) with a rated current of 20A.
Q4: How does the module handle overloads and short circuits?
For overloads, the automatic current limit caps the maximum output current to 110% of the rated capacity. In the event of a short circuit, the module protects itself from damage and is self-recoverable once the fault is cleared.
Q5: What is the operating efficiency and cooling method of this unit?
The unit offers high efficiency (over 93%, with parameter rated ≥92%) utilizing resonant soft-switching technology. It utilizes fan cooling, keeping the radiator temperature rise to ≤30℃ under Grade I continuous 100% full-load operation.
Q6: What operating temperatures are supported?
The module operates within a working temperature range of -10℃ to 40℃ (typical: 25℃) and can be safely stored in temperatures ranging from -40℃ to 60℃.
