Q: How is the ZXDU68 H002 V5.0 engineered to withstand harsh outdoor environments regarding IP rating, thermal design, surge protection, and battery safety?

The ZXDU68 H002 V5.0 utilizes a dual-layer insulated metal enclosure with IP55-rated ingress protection, operating reliably within an ambient temperature range of -40°C to +55°C. AC inputs feature Class C lightning and surge protection (nominal 20kA, max 40kA, 8/20μs), accompanied by robust DC surge and reverse-polarity safeguards. The thermal subsystem employs an integrated heat exchanger to isolate internal electronics from external dust, moisture, and salt-fog contamination. For battery safety, the system incorporates dual-route Low Voltage Disconnect (LLVD for non-critical loads and BLVD for battery protection), along with smart temperature compensation and insulated battery compartment walls to prevent over-discharge and thermal-induced capacity loss.

Question 1

What are the core electrical parameters and rectifier efficiency metrics of the ZTE ZXDU68 H002 V5.0 outdoor power system?

Accepted Answer

The ZTE ZXDU68 H002 V5.0 (SKU: ZTE-SYS-ZXDU68-H002-V5) is engineered for outdoor compact telecom sites, supporting an ultra-wide AC input range of 85VAC to 290VAC (delivering full rated output between 176VAC and 290VAC). It provides a nominal -48VDC output (adjustable from -42VDC to -58VDC) with a maximum system capacity of 150A. Populated with up to three ZXD3000 high-efficiency rectifiers, the system achieves a peak conversion efficiency >95.0%, with a power factor ≥0.99 and THD ≤5%. Driven by the CSU501C centralized supervisory unit, it delivers high-precision bus voltage stabilization and dynamic current limiting to ensure continuous, clean DC feed for RRUs and BBUs under fluctuating loads.

Question 2

What is the slot architecture of the ZXDU68 H002 V5.0, and does it support hot-swap capabilities and active load sharing?

Accepted Answer

The system chassis integrates 3 rectifier slots, supporting hot-swappable installation of both ZXD1500 and ZXD3000 rectifier modules. Rectifier units feature autonomous active load sharing with an unbalance tolerance < ±5%, enabling modules to evenly distribute current across the internal bus even during monitoring unit failure. Governed by the CSU501C controller, the platform provides RS485, CAN, Ethernet (SNMP), and dry contacts for northbound/southbound integration. It also features intelligent rectifier hibernation scheduling, turning off redundant units during off-peak, light-load hours to sustain maximum system operational efficiency above 95%.
