FAQ
Q1: Can this module charge lithium batteries directly?
A: Yes. The output voltage and current can be continuously adjusted, and custom charging curves for floating / equalizing charge are supported. We recommend using it together with a matched BMS battery management system for battery safety.
Q2: How many modules can be connected in parallel? Does it support hot swap?
A: Multi-module parallel and N+1 redundancy are supported. Hot-swap function is available. Modules can be replaced online without system shutdown, ideal for non-stop critical computer rooms.
Q3: Is the input single-phase 380V or three-phase?
A: Three-phase 380VAC input only. It does NOT support single-phase 220VAC. Three-phase five-wire connection is required.
Q4: Is remote monitoring available?
A: Yes. It comes with communication interface to connect with the monitoring host. Remote voltage/current adjustment, alarm checking and remote on/off control are supported.
Q5: What is the warranty period? How about after-sales service?
A: Standard warranty is 12 months. Free repair or replacement for non-human damage within warranty period. Lifelong technical consultation, fault diagnosis and spare parts supply are available.
