TX Matrix Plus Power Specifications
Table 1 lists the power system electrical specifications.
Table 1: Power System Electrical Specifications
Item | Specification |
|---|---|
DC input voltage | Operating range: –40 to –72 VDC |
DC system current rating | 191.6 A @ –48 VDC (nominal) (9200 W) |
We recommend that you provision a circuit breaker for each DC power supply input rated for at least 125 percent of the continuous current that the system draws at –48 VDC.
Table 2 lists the power supply electrical specifications for the seven-input 420-A power supply.
Table 2: Seven-Input 420-A Power Supply Electrical Specifications
Item | Specification |
|---|---|
DC input voltage | Nominal –48 VDC, –60 VDC Note: If the input voltage from the DC power source drops below -37.5 to -39.5 VDC, the router automatically shuts down. During automatic shutdown, the circuit remains active. When the input voltage returns to –43.0 to –44.00 VDC, the router automatically starts up again and the system returns to normal operation within 30 minutes. No operator intervention is required. |
Input DC current rating | 48 A @ –48 VDC (nominal) (2304 W) |
