Product Overview of ET48600 48VDC 600A Telecom Power System
The 6U 36kW Integrated ET48600 DC Rack Power System represents a compact, carrier-grade DC power conversion solution tailored for telecommunications central offices, mid-to-large scale data centers, and industrial settings requiring uninterrupted DC power. Operating from a single-phase 220V AC without a built-in circuit breaker, it employs rear copper busbars for wiring and provides fine-adjustable DC output ranging from –43V to –58V, with a nominal setting of –53.5V. With a peak capacity of 36kW, the system consistently achieves conversion efficiencies exceeding 96% across a broad load spectrum—lowering both electricity costs and cooling demands.
