Frequently Asked Questions
Q
What is the cooling method used in the BZA-110D40ZZ-3 rectifier?
The BZA-110D40ZZ-3 uses natural cooling via a radiator instead of a fan. This design eliminates noise from forced air cooling, improves reliability, and makes the unit suitable for a wide range of operating environments without the mechanical wear associated with fan-based systems.
Q
What is the rated output voltage and current of this rectifier module?
The rectifier provides a DC output voltage range of 95–150 VDC (nominal 110 VDC), with a default output voltage of 117 VDC. The rated output current is 40 A, and the maximum output power is 6000 W.
Q
Does the BZA-110D40ZZ-3 support hot-swap replacement?
Yes, the module supports hot-swappable operation, allowing maintenance personnel to replace or install the unit without powering down the entire system. This feature significantly reduces downtime and simplifies maintenance procedures.
Q
What protection functions are built into this rectifier?
The rectifier includes comprehensive protection and alarm functions: input under/over voltage protection, output under/over voltage protection, output current limiting (at 105% rated current), over-temperature protection, short circuit protection, and phase loss protection. LED indicators and LCD fault codes provide real-time status monitoring.
Q
What are the operating and storage temperature ranges for this unit?
The working temperature range is -10 °C to +40 °C, making it suitable for most indoor telecom and industrial environments. The storage temperature range is -40 °C to +60 °C. The unit also supports operation at altitudes up to 2000 m and humidity up to 95% RH (non-condensing).
Q
What communication interface does the rectifier support, and can it be used in a redundant configuration?
The BZA-110D40ZZ-3 is equipped with an RS485 communication interface, enabling remote monitoring and control. It also supports a modular N+1 redundancy design, meaning one or more backup modules can be added to ensure system continuity in the event of a single module failure.
