The PSE-3000 series power supplies, housed in a compact standard 1U package measuring 1.6 x 4 x 14in (41 x 102 x 356mm) offer a power density of 33.48W/in3, and achieve 80 PLUS platinum level efficiency.
In the PSE-3000-48, the power supply is pre-set to produce an output of 48V DC, with an adjustable output from 42V to 55V. In the PSE-3000-54, the 54V DC output voltage is intended for Power-over-Ethernet (PoE) applications.
Hot-swap blind-docking capability is implemented through the use of a single connector which integrates AC, DC and I/O signals. With a typical efficiency of 94%, the power supplies are ideal for telecom, server and networking applications in which the reduction of energy consumption is of critical concern.
The PSE-3000 power supplies support system communications via the I2C/PMBus™ protocol for control and monitoring of the unit. Stand-by outputs of 3.3V DC or 5V DC at 2A are provided. For maximum flexibility, the units are available in two configurations: with front-to-back airflow, or back-to-front airflow.
The power supplies carry 60950-1 safety approvals, and bear the CE mark. They comply with all applicable EMC requirements to enable worldwide usage. Protections for over-voltage, over-current, over-temperature, and input under-voltage are standard.
An optional 1U 19” power shelf is available to hold up to four power supplies for 12kW parallel operation, 9kW N+1 redundant operation, or dual 6kW A and B output-channel operation. The DC output terminal blocks can be configured to be single or dual polarity.
