Product Overview
The ZTE ZXDU98 B601 (V5.0) DC power supply system is based on modular design, combining a basic unit, a DC distribution extension unit and a rectifier extension unit, and supports mixed use of 50 A and 75 A rectifier modules. The basic unit provides six rectifier slots with a full-configuration capacity of 300 A (6 x 50 A) or 450 A (6 x 75 A), while the busbar is designed with 600 A capability so the system can be expanded up to 600 A (8 x 75 A or 12 x 50 A) by adding extension units.
As a complete embedded power system suited to tower-company sites and phased investment, the B601 supports intelligent battery on/off control (scheduled connection, exemption periods, disconnection by backup duration, battery voltage or battery capacity), hybrid operation with solar power by adding PU and PV modules, and intelligent peak shaving of load consumption to limit mains capacity requirements.
The basic unit measures 5U x 482 mm x 360 mm and extension units are only 1U-2U high, keeping the footprint compact in standard 19-inch cabinets. Three-phase 85-295 VAC input, module efficiency >= 95.5% and system efficiency >= 95% (40-90% load) deliver carrier-grade performance with MTBF >= 3.2 x 10^5 h.
