FAQ

Q1: What input power supply does the TH230D30NZ-6 require?
It requires a three-phase 380VAC supply (operating range 323–456VAC, 45–55Hz). Single-phase input versions are not supported by this model.

Q2: Can multiple modules run in parallel?
Yes. Modules can be paralleled with current sharing imbalance ≤±3%, supporting N+1 or N+M redundant configurations for seamless capacity expansion.

Q3: How does the module communicate with the monitoring system?
It supports both RS-485 (Modbus protocol) and CAN bus interfaces, allowing easy integration with your existing DC screen monitoring unit.

Q4: Is the module hot-swappable? What about maintenance?
Yes, it is fully hot-swappable. A faulty module can be replaced online without powering down the system, and protection (short-circuit auto-recovery, OVP, OTP) minimizes maintenance downtime.

Q5: What certifications and after-sales support do you provide?
The module is CE certified. We provide a 12-month warranty, factory-direct technical support, sample orders for testing, and OEM/ODM customization on request.
