What this product is

What this product is

This unit slots into ZTE ZXDU-series telecom power systems (such as ZXDU68 cabinets), converting AC power to stabilized DC and streaming telemetry via CAN bus to the central controller.

What problem it solves

Eliminates analog component drift, electromagnetic interference vulnerabilities, and load imbalance, providing microsecond-level fault response and active overload protection.

Who and where it is for

Engineered for 4G/5G telecom macro sites, backbone transmission facilities, edge data centers, and remote installations facing erratic utility grids.

Core advantages

  • Full Digital DSP Control Engine: Digital PWM regulation eliminates component aging drift and delivers robust electromagnetic interference resistance.
  • Ultra-Wide 80V to 300V AC Grid Window: Maintains continuous operation during severe utility fluctuations, preventing battery over-cycling.
  • High-Speed CAN Bus Integration: Communicates seamlessly with ZTE CSU controllers for dynamic voltage trimming and programmable current limiting.
  • Arc-Free Safe Hot-Swap Design: Ergonomic latching handle and low-impedance connector blades ensure smooth, spark-free field replacement.
