Telecom

With the increasing demands on power
supplies for today´s telecommunications
industry Benning have developed a
wide range of power modules.
Benning power
supply systems
have a modular
structure and
can be adapted
all customer
requirements.

Systems are available with wall-mounted
cabinets and floor-standing cabinets.
Using combination cabinets it is
possible to build in batteries with the
plug-in power supplies.

BLT-Power Supply-Systems
The following switched mode plug-in
rectifiers and BLT-systems meet the
requirements for compact and reliable
power supplies and have the following
principal features:
The modular structure of the BLTsystems
allows adaptation to almost
all requirements. All BLT-systems are
Plug-in Rectifiers
delivered with the monitoring system
MCU 500/1000 or MCU 2000+.
La Defense, Paris; – BENNING , power where it’s needed,
• efficiency ≥ 90 %
• power factor ≥ 0,93 / 0,98
• radio interference suppression to
EN 55022 level B
• noise voltage
≤ 1 mV or 2 mV CCITT
• excellent transient response
• temperature-controlled voltage
characteristic
Rectifier range PDT 400,
PDT 650, PDT 800, PDT 1800
This range is used for smaller power
systems. The mechanical layout allows
the arrangement of 6 plug-in rectifiers
(PDT 400 + PDT 650) side by side in
one 19“ rack. (Only without MCU
interface available.) The units PDT 800
and PDT 1800 are with or without MCU
interface available, 4 plug-in rectifiers
can be fitted in one 19“ rack.
