Power Supply Components of System Bays

Power Supply Components of System Bays

The Dorado18000 V3 storage system supports AC power and high voltage DC power. Both the North American and European standards for AC power transmission are applicable to storage systems. All bays of the storage system require the same power supply standard.

AC and High Voltage DC Scenario

Each bay of the Dorado18000 V3 storage system is equipped with two power distribution units (PDUs) on the two sides of the bay's rear end. This enables the storage system to have dual power inputs. Table 2-12 shows the number of PDUs based on each power supply mode.

Table 2-12 Number of PDUs based on each power supply mode (system bay)

Power Supply Mode

Number of PDUs

Single-phase AC: 220 V, 32 A


Three-phase AC: 380 V, 32 A


High voltage DC: 240 V, 32 A


North America three-phase AC: 208 V, 50 A


The appearances of PDUs are as follows:
