A user selectable standby output offers either 3.3 or 5VDC. Up to 3,500W can be delivered from a 230VAC input. Active PFC gives this unit a 0.99 power factor and less than 10% harmonic current. The D2U5T offers true three-wire three-phase operation without the need for a neutral connection and accommodates input voltages in the range 180- 264VAC for 3,500W operation and 320 – 525VAC for 7,000W output.
Packaged in an industry standard 2U format and delivering a 23.1W per cubic inch power density, the D2U5T is designed for use in broadcast, industrial and large data centre applications where high power conversion efficiency is vital. Up to three of these hot-swappable units can be connected in parallel operation and utilise droop current sharing to deliver increased power capacity to the system load or provide N+1 redundancy of supply to the application.
The D2U5T provides a number of features including over-voltage, over-current and over-temperature protection. LEDs give an indication of power supply status and any fault conditions occurring in the input, output or power conversion stages of the unit. Control and monitoring of the unit is also possible using the standard PMBus protocol via an I2C interface.
