The ZXDU68 S501 is an integrated rack-mounted -48V DC indoor power system incorporating AC/DC distribution, intelligent monitoring, and high-efficiency 50A rectifiers up to 300A capacity.
Need to confirm a model, specification, or project configuration? Our team can follow up by email or phone.
Built upon an intelligent digital control infrastructure, the system accommodates up to six 50A hot-swappable rectifiers (such as ZXD3000), integrated AC input switchgear, battery disconnection contactors, multi-branch DC distribution breakers, and a central supervisory unit (CSU) supporting SNMP/Web management.
Eliminates operational vulnerabilities associated with footprint constraints in dense indoor equipment rooms, excessive power dissipation from low-efficiency rectification, and inadequate battery health diagnostics.
Tailored for telecom operator central offices, cellular macro base stations, enterprise transmission hubs, and utility control sites demanding dependable -48V DC power.
