Frequently Asked Questions
What are the primary power output specifications of the 230D20NZ-D module?
The 230D20NZ-D delivers a rated output power of 6 kW with an adjustable output voltage range of 176 VDC to 300 VDC (typical 242 VDC) and a continuous output current of 20 A.
Does this power module support parallel connection and N+1 redundancy?
Yes. It features an N+1 hot backup modular design and advanced isolation automatic current sharing technology (imbalance < ±3%), supporting hot-swappable installation for easy expansion.
What communication protocols are supported for remote management?
The module is built with standard RS-485 and CAN communication interfaces, fully supporting automation systems with “4-remotes” functionality (remote control, telemetry, remote signaling, and remote regulation).
How does the automatic current limit and short circuit protection work?
In overload conditions, the module limits maximum output current to 110% of rated value in constant current mode. Under short circuit conditions, the module enters self-protection mode and automatically recovers once normal conditions return.
What is the input voltage tolerance of this rectifier unit?
The module accepts a 3-phase AC input voltage ranging from 323 VAC to 437 VAC (typical 380 VAC), ensuring stable performance during utility grid fluctuations.
What is the thermal management design and cooling requirement?
It utilizes built-in forced fan cooling, keeping the radiator temperature rise below ≤30℃ under continuous 100% Grade I load operation within a working temperature range of -10℃ to +40℃.
