Power Supply, 330 W, NEBS 3, Redundant, Universal AC-DC

The JDSU 1U-high power supply shelf contains two 330 W flat-profile power conversion cassettes that generate -48 V output. Each AC-DC unit is cooled by two internal fans and an alarm circuit, with Form C contacts, monitors the output voltage of each card.Mounting options include 19” or 23”, via reversible ears, and ETSI. The unit features front-accessible air filters with airflow direction from
front to back.

Rectangular current limiting protects output, while thermal shutdown and automatic recovery occur in the case of insufficient airflow.
