INTRODUCTION
The SETEC models BCE4 and BCE5 (battery charger/eliminator) provide a power
output of 140 watt at 13.6 and 27.2V respectively. The nominal input mains may be
200V to 240V and 50Hz or 60Hz (a 100 to 120V version is available, consult the
factory for details).
The BCE4 and BCE5 have been designed specifically for telecommunications
applications demanding high reliability, low noise, fully automatic battery backup,
battery protection and full protection of the output. Many other applications will be
able to take advantage of these features. Features include
• Light compact design
• High Efficiency
• Battery over discharge protection with automatic reset
• High reliability with conservative thermal design allowing continuous full load
operation with convection cooling
• Alarm for low mains and reverse battery connection
• User accessible battery fuse
• User accessible output voltage adjustment
• Low noise output, ideal for telecommunications applications
• 3 modes of operation
• Convenient output connector
• Flexible mounting options
• Full protection for the power supply, load and battery
• Local technical support

OPERATION
Safety
Correct installation is the most critical factor in ensuring the safe use of
the power supply. If every consideration in the Installation section of this
manual has been satisfied the power supply will be safe to operate.
Operating Modes
The BCE4 and BCE5 have three main operating modes:
• As a battery eliminator it may be used to power equipment requiring
12V –14V at 10Amps. (24 –28V at 5Amps for BCE5). It is fully
protected against overload and short circuit as well as incorporating
over voltage protection.
• As a lead acid battery charger it will provide safe and convenient
method to restore discharged batteries. Fully charged batteries can
be left connected to the unit indefinitely with no adverse effects on
their lifetime.
• The full features of the unit are realised when both a battery and a
load are connected so that it operates as a power supply with power
fail protection. Under normal conditions an internal switch connects
the battery in parallel with the load. The average load must be less
than the capability of the power supply to ensure there is a remainder
available to float charge the battery.
When a mains failure occurs, the power supply no longer provides
power. The battery now supports the load without interruption of the
load. Restoration of the mains restarts the power supply which will
resume support of the load and charging of the battery.
During extended mains failures the unit disconnects the battery
before it becomes excessively discharged. The battery is
automatically reconnected when the mains recovers. This feature
contributes to long battery lifetime and allows unattended operation of
a system.
Protection
The power supply incorporates the following protection features
• Reverse polarity connection of the battery will not cause damage to
the power supply or the battery and the output load will remain
unaffected.
• Battery fusing is provided in series with battery connection to protect
the load and power supply when it is powered from the battery.

• Accurate current limit protection is provided for both load and battery.
Automatic recovery from short circuit is provided with no current
tailing in short circuit operation.
• Over voltage protection provides shutdown of power supply.
• Inrush Surge limiting at turn on.
Battery LVD Operation
A low voltage disconnect (LVD) is provided to prevent deep discharge of
the battery.
When the mains has failed and the battery is supporting the load the
battery must be disconnected if its voltage falls below 10.2V ±0.2V (20.5V
±0.6V for BCE5) for longer than approximately 800mS.
The battery will reconnect in such a case when either;
1. The mains has recovered and the battery voltage is > 9.5V or;
2. The battery voltage has recovered to greater than 11.9V ±0.3V
(23.5V ±0.7V for BCE5) for longer than approximately 2 seconds.
The BATTERY output has protection incorporated against a reversed
battery connection. A reversed battery is left disconnected so that the
LOAD output can still run the load from mains power.
The quiescent current drain on the battery when the main has failed is
less than 30mA.
Indicators
A green LED (located next to the output connector) is illuminated during
normal operation. An alarm condition extinguishes the LED.
Alarm
A green LED and a pair of normally closed, floating relay are provided to
indicate alarm conditions. The LED is illuminated and the alarm relay
contacts are open during normal operation. An alarm condition
extinguishes the LED and closes the relay contacts. Alarm conditions are
defined as any one or more of the following events:
The mains fails, or drops to below nominal input.
The battery has been connected backwards.
Output Voltage Adjustment
The output voltage is adjustable through the side of the power supply.
Use a flat blade pot adjuster to adjust the output voltage. Clockwise
rotation increases the output voltage.

When adjusting the output voltage, measure the voltage at the output
connector with the battery disconnected. Failure to disconnect the battery
can result in incorrect output voltage setting, and over charging of the
battery may result.
The output voltage is factory set to 13.65V (27.20V for BCE5)
