Learn about the JNP-PWR-3K-AC PSM used on the PTX12008 and its specifications.

The JNP-PWR-3K-AC PSM supports AC, high-voltage AC (HVAC), or high-voltage DC (HVDC) input. The PSM automatically detects whether there is AC, HVAC, or HVDC input and manages the power accordingly. The PSM provides 3700-watt (W) DC output.

Each PSM has its own built-in fan and is cooled by its own internal cooling system. Hot air exhausts from the rear of the chassis.

Each PSM has two independent 24-Amperes (A) rated AC/HVAC/HVDC inlets on the faceplate. Though each inlet provides sufficient input power to provide full output, always connect both inlets to dedicated AC/HVAC/HVDC power sources to provide redundancy.

Each JNP-PWR-3K-AC PSM has a handle, an ejector lever, a power switch with international markings for on (|) and off (O), two AC/HVAC/HVDC inlets, and four status LEDs on the faceplate.

Table 2 shows the physical specifications of the PSM.

Learn about the JNP-PWR-3K-DC PSM used on the PTX12008 and its specifications.

The JNP-PWR-3K-DC PSM can operate with an input current of either 60 A or 80 A. The PSM has two independent pairs of DC input lugs (labeled Input 0, RTN, –48V/–60V and Input 1, RTN, –48V/–60V) on the faceplate of the PSM. Each inlet requires a dedicated DC power feed. You must always connect each of inlet the PSM to a dedicated DC power feed to provide redundancy. Only one power feed is operational at a time. You can configure the input using a dual inline package (DIP) switch on the PSM faceplate.

Each PSM has its own built-in fan and is cooled by its own internal cooling system. Hot air exhausts from the rear of the chassis.

Each JNP-PWR-3K-DC PSM has a handle, a power switch with international markings for on (|) and off (O), a dual inline package (DIP) switch, an ejector lever, an input tray, and four status LEDs on the faceplate.
