Description

The back plane types BPF1000 and BPD1000 have been

designed for fast and simple set-up of 19" rack mounted

power supply systems powered by AC-DC converters of the T

series. Battery charger systems, telecom rectifiers and

modular power bus systems can easily be configured with

n+1 redundancy if required. Three T Series converters can be

plugged into one back plane providing up to 1.6 kW output

power.

Since for such applications the status of the power bus is of

importance rather than the output status of a single AC-DC

converter, T units with option D should be chosen enabling re-

mote bus voltage sensing.

The back plane concept allows system assembly in next to no

time. When fitted in the rack all input and output terminals are

readily accessible from the rear. The AC input is designed for

single or 3-phase operation. The monitoring signals and the

control signal inputs and outputs are available from a screw

terminal strip. System specific signal combination is possible

with different jumper settings. The back plane fulfills in this

way the function of a controller unit.

The layout of the back plane and the hot plug-in capability of

the AC-DC converters allow system expansion under load

(e.g. from 550 W up to 1.6 kW) by simply inserting further

T units into the rack. Larger system power extension is just a

matter of interlinking the DC output rails and signal outputs of

two or more racks.

The back planes are available in 2 basic versions:

BPD1000: A front-end version, fitted with decoupling di-

odes in each positive line to the DC bus, for systems

with 2 or more T units in parallel or n+1 redundancy.

BPF1000: A battery charger version, in which each out-

put is fitted with a fuse in the positive line to the DC bus,

for battery charging or rectifier systems with two or

more T units in parallel or n+1 redundancy.

For minimum electromagnetic emission at the input, both the

BPD and the BPF versions are fitted with input filters. Should

project specific requirements demand enhanced hold-up

time or lower output ripple (low frequency ripple) than

specified for the individual AC-DC converters, both basic back

plane versions are available with additional output capacitors.

Important: The neccessity to provide a cover over the live

parts at the mains input (High Voltage) or over the DC bus bars

(Energy Danger), preventing accidental contact during instal-

lation, start-up of a system or maintenance, depends on the

final installation as well as on the applicable safety require-

ments. However, it is the responsibility of the installer or user

to provide such a safety cover to assure the compliance with

the relevant and applicable safety standards.
