FAQ
Q1: Does this module support hot swapping? Will it damage the
equipment?
A: It supports native hot-swappable design for non-stop maintenance.
The plug-and-swap process brings stable voltage and no inrush
current, causing no damage to load equipment and fully meeting the
uninterrupted operation requirements of computer rooms.
Q2: Do I need to adjust parameters manually for parallel use of
multiple modules?
A: No manual adjustment is required. The module is built with an
intelligent current sharing function with parallel accuracy ≤±5%.
It automatically balances load after power-on, featuring simple
plug-and-play expansion.
Q3: Is the output voltage adjustable? Can it adapt to different
devices?
A: The output voltage is adjustable from 40V to 58V DC, compatible
with battery charging, conventional 48V communication equipment and
various load scenarios with strong universality.
Q4: Will the module fail in high-temperature environments?
A: The operating temperature ranges from -10℃ to +40℃. Equipped with
intelligent temperature-controlled variable-speed fan and
over-temperature protection, it automatically cools down at high
temperatures and shuts down for overheating protection to avoid
burnout and system failure.
Q5: Does it support remote monitoring and fault alarm?
A: Yes. It is equipped with RS485 and SNMP communication protocols,
which can be connected to the computer room monitoring system to
view real-time data of voltage, current, temperature and load, and
upload fault alarm information automatically for convenient remote
