Question 1

What are the core electrical performance parameters, AC input range, and power conversion efficiency of the ZTE ZXDU68 B201?

Accepted Answer

The ZTE ZXDU68 B201 is a 5U 19-inch rack-mounted embedded DC power system with a nominal output of -48V DC (adjustable from -42V to -58V DC). Fully equipped with four ZXD3000 50A rectifier modules, it delivers a total capacity of 200A (approx. 11.6 kW). The system accommodates an ultra-wide AC input range of 80–300 VAC (compatible with both 220V single-phase and 380V three-phase grid architectures) with linear derating between 85–176 VAC to maintain uninterrupted telecom operation. Featuring soft-switching resonant topology, the system achieves a peak conversion efficiency exceeding 96.0%, a power factor (PF) ≥0.99, and THD ≤5%, minimizing energy loss and operational OPEX in telecom sites.

Question 2

How does the ZXDU68 B201 subrack handle module compatibility, autonomous current sharing, and low-voltage disconnect (LVD)?

Accepted Answer

The ZXDU68 B201 provides four hot-swappable slots natively designed for ZXD3000 50A rectifiers, enabling seamless N+1 redundant scalability from 50A to 200A. The rectifiers employ high-speed CAN bus digital active load-sharing technology, keeping the current unbalance rate below ±3%. Governed by the CSU502A/CSU500B intelligent supervisory unit (supporting SNMP via Ethernet and RS485/RS232), the subrack integrates dual-level Low Voltage Disconnect: LLVD (Load LVD) for shedding non-critical loads and BLVD (Battery LVD) for deep discharge protection across dual battery branch inputs, ensuring mission-critical carrier-grade uptime.

Question 3

What protective engineering designs allow the ZXDU68 B201 to withstand harsh thermal, surge, and unstable grid environments?

Accepted Answer

The ZXDU68 B201 is built to IP20 mechanical standards and supports an operating temperature range of -40°C to +70°C (with linear derating above +55°C). Rectifier cooling utilizes temperature-controlled brushless fans with an isolated front-to-back airflow channel that protects critical components from dust and corrosive particles. For surge resilience, it integrates a Class C AC SPD rated at In=20kA and Imax=40kA (8/20μs waveform), supplemented by multi-stage DC and signal transient overvoltage suppression. The system also features battery thermal compensation, input over/under-voltage auto-cutoff, and short-circuit hiccup recovery protection.
