Installation and User Guide
ALPHA units have been designed to charge any current type of batteries. Thanks to their simple interface, they
provide all necessary settings as well as simple operation monitoring. Incorporating protections and basic
functions, they are easy and quick to set up. They guarantee a reliable operation and good care of the batteries
that will extend their life even when used in harsh conditions.
It is also possible to set ALPHA unit as a power supply. Optional supervision printed circuit boards convert
ALPHA units in smart systems dedicated to your applications. They feature complex functionalities that are
nevertheless easy to use thanks to a user friendly man-machine interface.

Battery charger mode
ALPHA is delivered in battery charger mode as a factory setting. Output voltage is predefined for VLRA
batteries at 2.27 V per cell, or 13.6 V, 27.2 V, 54.5 V or 136.2 Vdc according to the model. When the desired
output voltage is different, i.e. when using a nickel-cadmium battery with 1.42 V per cell as a recommended float
voltage, it is possible to adjust output voltage by roughly ±5% using U potentiometer.

ALPHA 120V model (for a 60 lead acid cell battery) and 240V model (for a 120 lead acid cell battery) can be set
to 110V (for a 54 lead acid cell battery) and 220V (for a 108 lead acid cell battery) by setting switch 4 of mode
selector in the opposite position (opposite to “normal”).
Power Supply mode
To use ALPHA as a power supply, set switch 1 of mode selector in the “Power Supply” position. Factory setting
is then 12, 24, 48, 120 or 240 Vdc according to the model. Output voltage can be adjusted by roughly ±5%
using U potentiometer.
3 ADVANCED FUNCTIONS
Battery current setting
ALPHA charger possesses two current regulations. This allows to set the charging current of the battery. To
limit the charging current to the correct value (recommended 10% of the battery capacity C10), use IB
potentiometer. Factory setting corresponds to 10% of the nominal current of the charger. One turn of IB
potentiometer equals 5% of the nominal current of the charger. When turning clockwise, current increases up to
nominal current. Note that this affects only the battery output.
Boost function
To faster charge the batteries, it is useful to set the voltage at a higher level for several hours. ALPHA Charger
features a BOOST function that raise the charging voltage by 3.8%. This function is activated by strapping
terminals 10 and 11. Cable shall not to exceed 2 meters. Releasing the strap resumes normal operation.
Static stop command
It is possible to force ALPHA to stop using an external command. Remove factory installed strap between
terminals 8 and 9 (On/Off static stop) and insert a switch or a dry contact. Unit is stopped when contact is open.
Output voltage U setting using external potentiometer
It is possible to set output voltage U from 0 to 125% of ALPHA nominal voltage using an external pot. Before
powering the unit, connect the potentiometer (only use VERTIV Potentiometer kit code 6002928) as shown in
schema. Set switch 2 in position « External setting ». Resume power.
Current IB setting using external potentiometer
It is possible to set current IB on battery output from 0 to 100% of ALPHA nominal current using an external pot.
Before powering the unit, connect the potentiometer (only use VERTIV Potentiometer kit code 6002928) as
shown in schema. Set switch 3 in position « External setting ». Resume power.
Protections
ALPHA contains internal devices to protect itself and to protect the connected load:
▪Protection against reverse polarity (warning, it is mandatory to respect FB and FU fuse ratings, see
table)
▪Protection against overload and short-circuit by output current limitation.
▪Protection against fire in case of internal fault by internal input fuse.
▪Protection against output overvoltage: secure the load in case of regulation loss by stopping the unit.
Overvoltage set to 105% of nominal voltage for more than 2 seconds.
▪Thermal protection against abnormal temperature and heat dissipation.
These two last defaults are reported on the fault relay (dry contact NO + NC terminals 1-2-3, signals a fault in
normal position). To reset, remove power for at least 30 seconds.
Please respect mounting position: vertical position, connectors facing down (side mounting is possible).
Verify that vents are not obstructed. 50 mm required above and below unit.
Verify that nominal voltage corresponds to the application.
Make sure that battery and load are connected to their respective connector.
Verify positive and negative polarity on battery and load.
Verify that metallic assembly is connected to the earth.

4 OPTIONS
Supervision kit Quartz
Supervision kit Quartz (ref. 6 007 981) can be associated to ALPHA charger. This kit includes a supervision
PCB, a display with two lines of eight caracters and a I/O PCB for six inputs and 5 outputs. Quartz supervisor
offers a wide range of parameters for an advanced automatic battery charger. Displays of voltage, current,
alarms, faults of both output and battery grant the user management of the complete system.
Potentiometer kit for analogue control
This kit contains a ten-turn potentiometer (ref. 6002928). It allows a fine analogue setting of the output voltage U
or the current of battery branch IB.
5 TROUBLE SHOOTING
No output voltage and mains present LED off
Make sure power is present at ALPHA input and DJS is closed.
No output voltage and mains present LED on
Make sure there is a strap between 8 and 9 terminals, or static stop command is closed if wired.
Verify if fault relay signals a fault. In this case, remove power for at least 30 seconds. Make sure vents are not
obstructed, and ambient temp is not too high. Power on again.
Output voltage is not the one desired
Make sure you are using the right model (see name plate). Verify position of the mode selector switches (see §
technical data). If you are at less than 5% of the desired voltage, adjust again the output voltage using
potentiometer U.

Note: Charger or Power supply, values in this table are factory settings. Potentiometer U allows adjusting output voltage by roughly ±5%.
When terminals 10 and 11 are strapped, output voltage raises by 3.8% (Boost function).
To avoid any control perturbation, it is recommended:
▪not to exceed 2 meters for cabling the auxiliaries
▪not to bring auxiliaries cables outside charger cabinet
▪to separate auxiliaries cables and power cables
▪to twist auxiliaries cables serving the same function
