TPG2233 UniPower Hot-Plug Power Supply Module

The UniPower TP Series Hot-Plug Power System is a switching hot-pluggable power system with N + 1 redundancy. The standard system consists of (3) hot-pluggable power modules in a 3.5-inch high by 19-inch wide chassis. The chassis mounts in a standard 19-inch rack.

In N + 1 redundant operation this system can provide up to 1200-watts for a single output or up to 1000 watts for a triple or quad output. For non-redundant operation, the power levels are 1800 and 1500-watts respectively. A six-module system, consisting of two stacked three-module systems, can provide up to 3000-watts N + 1 redundant or 3600-watts non-redundant.

There are (34) standard hot-plug modules in the UniPower TP Series. Each module can supply up to 600-watts for a single output or up to 500-watts for a triple or quad output. The modules have built-in output isolation diodes, and each module is individually fan-cooled. High reliability hot-plug connectors are used in the modules and the chassis. For N + 1 redundant or for non-redundant operation, the outputs must be externally connected in parallel by the user; the current share terminals must also be connected together. The system can be manufactured with customer-designated backplane connections.

The UniPower TP Series Hot-Plug Power System incorporates a number of important features such as active current sharing, N + 1 redundant operation, remote sensing on all outputs, Class A EMI input filter, electronic inrush current limiting and thermal protection. An additional feature is no load operation which permits any output to be operated down to zero load. Options include input autoranging, DC input (42-60VDC) and extra mounting brackets. Control and supervisory signals include high and low margining, output inhibit, power good, and DC OK.
