FAQ
Q1: Can TH48T75NZ-S work in parallel with other rectifier brands?
A: We suggest running same TONHE modules together for stable current sharing. Mixing different brands may cause current imbalance.
Q2: Is this module hot-swappable? Do I need to shut down the whole cabinet?
A: Yes, it supports hot swap. You can replace a single faulty module without cutting off the whole 48V bus of the telecom cabinet.
Q3: What certificates can you provide for telecom tender?
A: We can provide CE, test report, factory ISO certificate, commercial invoice, packing list, CO and Form E according to your destination country requirement.
Q4: Can I adjust the output voltage and battery charge parameters remotely?
A: Yes. Parameters are adjustable via the power system controller through Modbus communication.
Q5: What is the lead time for bulk telecom cabinet orders?
A: Small stock orders: 3–7 working days. Large project bulk orders: 15–25 working days, we will confirm schedule before order.
