3. ESTEL 48v Telecom Power Supply
A rectifier converts alternating current (AC) to direct current
(DC) and provides the power necessary to charge batteries. With a
focus on continuously improving the total cost of ownership,
ESTEL’s rectifiers, combined with advanced control and monitoring
features, help reduce both capital and operational expenditure. Our
rectifiers boast excellent power density while fulfilling space and
weight requirements. They leave plenty of room for other equipment
and create savings in packaging and transportation costs. In
addition, their high efficiency lowers total energy consumption and
reduces carbon footprint.
ESTEL’s rectifiers are easy to install, as their connectors are
located at the rear and are hot-pluggable. Fan cooling with speed
control renders operating almost silent. In general the rectifiers
include a wide AC input voltage range, protection against AC
overvoltage and optional protection against loss of neutral, which
make this solution very reliable even in the regions with AC
utility network problems.

6. Subrack Installation
Install the subrack to the 19-inch rack, as shown in Figure below.
Ø Step 1,Remove the plug from the package.
Ø Step 2,Push the plug into the 19-inch rack
Ø Step 3,Install the fixed screw (if the mounting hole of the plug
frame ear does not correspond to the position of the floating nut
of the frame,
it needs to be adjusted according to the actual installation).
Install Rectifier/Solar module
Ø Step 1, Take out the module from the package.
Ø Step 2, Hold the module handle on the front panel and put the
module onto the slot.
Ø Step 3, Push the module slowly to the front panel of the module
and flush with the power
distribution panel.
Ø Step 4, Tighten the fixing screw on the module panel so that the
module does not come off.
