Telecom

General
With the increasing demand for power systems in
the telecommunication sector, and the need for
more efficient use of operating and maintenance
staff, Benning have produced a range of system
monitoring. The Benning MCU 500, MCU 1000 and
MCU 2000+ offer the user a solution depending
on the customer requirements.
BLT 150 and BLT 400 power systems are fitted
with MCU 500 (Optional MCU 1000) monitoring
system.
By means of local indication (13 off LED´s) and
numerical display, the system status can be
quickly assessed.
The MCU 1000 additionally offers direct communication,
via a RS 485 interface, with the rectifier
modules.
As an optional extra the MCU 1000 may be fitted
with a relay box having 8 volt free contact.

The BLT 2500/5000 has the MCU 2000+ monitoring
fitted as standard.
Both MCU 1000 and MCU 2000+ monitoring
systems have the facility to control and monitor
the power system via the public telephone
network.
As an option, the MCU 1000 and MCU 2000+ signals
can be transmitted via modem to a central
control station.
