Two digital panel meters (LED). Constant voltage and current operation. Output switch off function (output standby). Overload and reverse polarity protection. High power density. Use the Dual 48 VDC power supply to power your Datacom Systems’ network taps, multi-link aggregators and SPAN port regenerators. The Dual 48 VDC power supply accepts connections on terminal block connectors for 48 VDC plus (+), minus (-) and ground connections. DC power jack cables are provided for connectivity from each power supply to the network tap, multilink aggregator or SPAN port regenerator. Each DC input terminal block connector provides a 5 Volt output. The dual power supply can be used for fault tolerant redundancy. Dual 48 VDC inputs. Dual 5 VDC outputs. 2 (two) 5 VDC cables included. Includes convenient rack mount ear. Optional 1U rack mount holds 3 power supplies.
