Question 1

What are the core electrical specifications, input voltage tolerance, and efficiency ratings of the ZTE ZXD3000 (ZTE-REC-ZXD3000-60A) rectifier module?

Accepted Answer

The ZTE ZXD3000 is a 1U high-density telecom rectifier delivering a rated output power of 3000W and a continuous output current of 60A at a nominal -48VDC (adjustable from -42VDC to -58VDC). It features an ultra-wide AC input range of 85VAC to 295VAC, delivering full 3000W capacity between 176VAC and 295VAC (with linear derating from 176VAC down to 85VAC). Built with active PFC and soft-switching topologies, it achieves a power factor of ≥0.99, THD ≤5%, and a peak conversion efficiency of 96.5% (≥96% nominal), drastically minimizing heat dissipation and operational PUE across telecom central offices and edge data centers.

Question 2

How does the ZXD3000 integrate into power subracks, and what are its hot-swapping and active load-sharing capabilities?

Accepted Answer

Engineered in an ultra-compact 1U form factor (41.5mm H x 132mm W x 300mm D), the ZXD3000 natively integrates into ZTE ZXDU68-series power subracks (such as ZXDU68 S601 and ZXDU68 B201) as well as standardized -48V high-density DC distribution shelves. It features true live hot-plugging capability and intelligent active digital current sharing with an imbalance rate under ±5% across parallel modules. Equipped with high-speed CAN bus communications, the module dynamically interfaces with the Central Supervision Unit (CSU) for auto-addressing, real-time telemetry, remote voltage/current-limit trim, and intelligent modular sleep scheduling for optimized low-load system efficiency.

Question 3

What protection mechanisms and environmental ruggedization standards ensure the ZXD3000's reliability in extreme conditions?

Accepted Answer

The ZXD3000 is hardened for harsh mission-critical environments, operating within an ambient temperature range of -40°C to +75°C (delivering full 3000W output up to +55°C, with linear thermal derating up to +75°C). Cooling is managed by an internal intelligent speed-regulated brushless DC fan with front-to-back airflow. Electrical survivability is fortified by AC input over/under-voltage disconnect with hysteresis, output hardware over-voltage clamp/latch, output short-circuit/over-current self-recovery, and over-temperature shutdown. The AC port conforms to IEC 61000-4-5 surge immunity standards, supporting a demonstrated MTBF exceeding 300,000 operational hours.
